  1. Hey everyone im busy building up a pyga slakline and for the time being I am going to be using 2 pot brakes but I want to upgrade my budget is under 5k any ideas?
  2. Hi Guys Before posting a for sale ad, keen on some technical info - if there is indeed ANY market for a nice set of Shimano XT STI Dual Control combo - (brake and gear lever combo), off of an older SPEZ S-Works Epic? they would work with cantilever brakes, and both my Spez frames have got the brazed on 'BOSS' for cantilever brakes, but I am now running hydraulic disks set up.... Anyone advise me? Are there guys who rebuild/restore period-correct, pre-Disk MTB's? Cheers Chris
  3. Shimano introduces a new drivetrain technology today, Linkglide. It’s designed not to be the lightest weight but to prioritise durability and shift performance. It also represents something of a fork in the road for the brand’s drivetrains. There will still be Hyperglide+, and this will remain the lightweight fast shifting performance range, while Linkglide will sit alongside their current offerings, as opposed to replacing them. Shimano claims that their testing shows that Linkglide cassettes are 300% more durable than prior Hyperglide cassettes, and three times less degradation to the cassette should mean fewer chain skips, more mileage, and better shifting long into the cassette’s lifespan. Linkglide will be available in either 10 speed Deore (RD-M5130-SGS) or 11 speed Deore XT (RD-M8130-SGS).Before we all celebrate too quickly, there is one small catch - the Linkglide technology, while introduced in Deore 1x10 or XT 1x11 speed as a highly durable option, is not cross compatible or retrofittable with current drivetrains due to different gear pitches. All Linkglide components will feature a logo to differentiate them from their stablemates. A CS-LG600-11 11-50T XT cassette, pictured, weighs 780g. The CS-LG600-10 11-43T Deore cassette is slightly lighter at 634g.The teeth of Linkglide cassettes are made from plated steel with a new shape to reduce wear and tear. The teeth feature a thicker and more robust construction to prevent wear in the areas that experience the most degradation over time. Linkglide cassette teeth are also taller and stronger towards the tips to prevent chain skipping and tooth deformation, even as the miles add up. Sprockets 11T, 13T, 15T of the cassettes are replaceable. The Linkglide cassettes also feature a new shifting gate design and position, enabling the chain to move smoothly across the sprockets. These gates aim to reduce pedal shock or jumps during shifting, providing better pedaling fluidity and smoother pedaling performance. The SL-M8130-R XT shifter; the SL-M5130-R Deore shifter is available with an optional shift window.Two new shifters, again Deore and XT, are available. The XT has multiple clamping options whereas the Deore makes do with a simple band. The shifters use a different pull ratio to the rest of Shimano's range so are not compatible with non-Linkglide systems. They are, however, somewhat interchangeable with each other thanks to a linear pull ratio. That means an 11 speed shifter will work on a 10 speed derailleur. Linkglide cassettes are compatible with standard HG freehubs. To accompany the new Linkglide cassettes, there are also new Deore XT and Deore derailleurs and shifters. The derailleurs feature Shimano’s Shadow RD+ low profile design and clutch mechanism. All Linkglide drivetrains use a common chain design, regardless of the number of cogs on the cassette. Existing 11-speed Shimano chains are compatible with Linkglide drivetrains. It’s perhaps also worth noting that all Shimano 11-speed chains are currently e-bike rated or e-bike designed.
  4. I have a choice of the following wheelsets Mavic aksium elite evo ust Shimano rs500-tl Fulcrum Racing 600What wheelset will you pick, or any other wheelset in the same price. https://bike.shimano.com/en-EU/product/component/ultegra-r8000/WH-RS500-TL-R.html https://www.fulcrumwheels.com/en/wheels/road-bike-wheels/racing-6 https://shop.mavic.com/en-be/aksium-elite-ust-rr1147.html
  5. Hi there. I need some advice please. I have Shimano XTR brakes which I have bled (flushed front and rear and added new mineral oil) but it still feels spongy. I have new pads at the rear and measured both the rotors at 1.65mm. Left the bike upright for about a day with the screws open on the levers to let any air bubbles out. Topped up with fluid. Also tried inserting the fluid from the bottom and the top, but neither seems to work. Not sure what to do anymore. Can anyone perhaps assist please? TIA
  6. The partnership will see Shimano leveraging 20 years of neutral support experience and know-how to support all riders in selected A.S.O. races, no matter which drivetrain brand they use, helping them to get their bikes operating at the optimum level. The iconic blue of Shimano will adorn the neutral support cars in all A.S.O. World Tour, Continental and Women’s races, offering all riders assistance to get back on the road as quickly as possible in the event of a crash or mechanical issue. The new agreement complements Shimano’s 20-year old neutral support program which originated at the Spring Classics such as the Tour of Flanders and Amstel Gold, and progressed to La Vuelta, where Shimano already has a strong working relationship with the A.S.O., and latterly to the Giro D’Italia, helping Shimano in its goal of becoming the favoured brand for consumers and customers alike. Taizo Shimano, Executive Vice President said: “In the one hundredth year of our existence we are very excited to start a new chapter in our sports history. We are proud to announce a partnership to support the A.S.O.’s events with neutral support. That means we will be providing first-class support to riders at A.S.O. events to get them back on the road and back in the race. “Shimano’s role is to inspire people to participate in sports and to keep bicycles running at their best. The vital neutral support role, especially at cycling’s most high-pressurized race – and also at one of the world’s most-watched sporting events – will allow us to do just that. “Working with A.S.O. will allow Shimano to provide more support to the sport and more support to athletes to help them perform at the top level. “As a company we take great pride in the quality of work that the thousands of global Shimano dealers carry out. This partnership with A.S.O. is the best example of the service that they provide. Not only do we hope this partnership will inspire a new generation of people to ride their bikes more often, but we hope to inspire people to trust in our product quality.” Yann Le Moënner - Managing Director of Amaury Sport Organisation: "We are incredibly pleased to have extended our partnership with a player as innovative as Shimano. Partnering up on all of our professional and amateur cycling events with a family business and pioneer in the cycling world testifies to our commitment to offering excellent support to athletes as well as all of the cyclists involved in our events. The innovation and consistent level of excellence provided by the brand over its 100 years of existence make Shimano a crucial player in world and everyday cycling and a brand that we are proud to be associated with." Shimano first engagement for A.S.O. this year comes at Paris–Nice starting in Saint-Cyr-l'École, France on Sunday 7th March 2021.
  7. First off I must stress that I am by no means a qualified bicycle mechanic, I do have little very little experience with them. Secondly I cannot take full credit for this fix, the idea was given to me by a very very generous hubber who’d had offered to fix for me for free. KUDOS @BikeWhisperer and a close friend @gyro for the time Ok, then this is not an avid or shimano appreciation thread, nor an avid vs shimano thread. SYMTOMPS: Pull lever, and it does not return at all or very slow and spongy. If bike in open sun, levers lock up. POSSIBLE CAUSES: Dirt and grime build up in the lever cylinder, as well as on the piston. See below With the dirt and grime build up, when in heat the swelling cause the lockup and no return of lever. TOOLS NEEDED: 2mm Allen Key Star Screwdriver Isopropyl Alcohol Toilet roll/Roller towel Thin Nose Pliers 1 x 3000 grit Sand Paper 1 x 2000 grit Sand Paper 1 x 1000 grit Sand Paper This is from the shimano site, I will make reference to the number here in my photos as well For starters is always good to remove the lever completely off the brake line. Below is an image of a lever I had repaired and one that was going to get repaired, taken as is off the brake system Remove 8 in diagram above like below, there a tricky little rubber cover than can be removed with a thin small screwdriver or pin Push out 5 using the 2 allen key, this will separate the lever trigger from the rest of the lever Use the thin nose pliers to twist and remove the roller connector/part of the lever Using the star screwdriver, remove 6 Turn the lever upside down ie. reservoir facing down and use the screw driver to pop out the plastic roller fitting ..and finally we get to the problem child, this is just to show you how the piston is actually stuck in the cylinder Easiest way to remove the piston and spring is using the 2mm allen key This is your best friend keep on using it throughout the process, clean up all you bits you can, all the none plastic and rubber bits I let sit in the isopropyl alcohol for a few mins …so time for the fix the red blocks is whats needed to be sanded down using the 1000 then to 2000 then smoothen with the 3000, very very lightly and depending on your piston condition very very little too. PS: it may or may not be easier to remove the rubber seals, just be very careful when sanding around them what I do to test I push the spring in with the piston, and see if there’s a “spring” back in the piston by pushing in and out the cylinder And the final product! DISCLAIMER: I am not in any way affiliated to Shimano. I will not take any responsibility for any damage done to your lever or other parts when attempting this fix. I am not 100% sure of the repercussion sanding down the old dirt or grime build up, and will not be held responsible if it does fail. Our scholars tell us, that we have to go out to seek knowledge and whatever knowledge is learnt must be shared so it be beneficial for myself but humanity at large…
  8. Help Needed!!! I am relatively new to mtb and ride and enduro 27.5 650b. I am running a shimano xt 2x10 group set with a Thirteen hub. I want to upgrade to better suite my riding. I have a budget of +-10000 rand but I am not sure what drivetrain/grouplet to go for and am looking for recommendations. I really enjoy the DH stuff but do like the distance so looking for something that does both well. Help would be greatly appreciated.
  9. Hi all, I am at a crossroads here. I broke my one Shimano XT 2x shifter, so the one thought train is to instead of replace with another 2x10 shifter set, to make the jump and upgrade to 12sp. The catch comes in that I have a power tap rear disc hub (G2), a non-boost (QR) frame and I am trying to find a way to minimize the changes required.. The current options are as follows: Sunrace 11-50T cassette (MZ90), which is suited specifically to SRAM drivetrains., and then go SRAM GX? Sunrace 11-51T cassette (MZ903), suited to Shimano drivetrains. I cannot find stock of this in SA. The thought would then be a Shimano SLX drivetrain? I believe the difference is in the spacing they implement on the two cassettes. The 11T at the bottom negates having to change the hub, and will fit a standard Shimano HG freehub or equivalent (Non micro spline hubs). Crank is not an issue, as that can be easily converted. Does anyone have any other suggestions that work or are known to work in this scenario? All suggestions are welcome. For those that have tested SLX and GX, what would be the verdict, considering pricing and spares? Regards.
  10. E-bike components The new KORYAK E-PERFORMANCE MTB handlebar is the world’s first integrated handlebar/stem/grip designed to accommodate an e-bike computer with a recess area in the middle section. The handlebar specifically caters for e-MTB riders who tend to spend more time in the saddle and who are looking to upgrade their e-MTB for improved performance. The KORYAK E-PERFORMANCE MTB handlebar features a recess area for the SHIMANO STEPS computer, positioning the computer safely within a cradle to provide a clearer visual of the data in the blink of an eye. The performance aspect comes from its carbon construction and shaping, offering internal cable routing and compliance in terms of vertical comfort and stiffness in terms of lateral steering direction. The E-PERFORMANCE handlebar has an 800 mm width for assured control, a 65 mm stem extension with a 49 mm reach (due to the backsweep design), plus a sloping 20 mm rise and an 11 degree backsweep to reduce hand pressure. The handlebars can accommodate all current SHIMANO STEPS e-MTB system computers and come with contoured grips to match the switch paddles on the SHIMANO STEPS left hand drive unit mode switch. Mountain bike components The new THARSIS components are designed to follow XC and Down Country trends for stiffer components. The THARSIS 3FIVE 35 mm oversized carbon handlebars now come in five varieties, the THARSIS 3FIVE Flat, Flat Top, Mini Rise (also available in alloy), Rise and High Rise together with an alloy 7050, 9 degree +/- oversized THARSIS 3FIVE stem (available from 60-100mm) for XC racing. Finally two new internally cable-routed Dropper Seat Posts (DSPs) will be released from PRO this autumn. The first THARSIS post is a race-level product featuring a short 100 mm of travel for 27.2, 30.9 and 31.6 mm seat tubes and should be used on XC, Down Country or Gravel bikes. The post is made from 3D forged alloy with a lightweight titanium 2-bolt head design and is 400 mm in total length, weighing 415g in total, saving over 15% in weight compared to existing Koryak posts. The second dropper seat post comes ready for the new standard 34.9 mm seat tubes appearing on Enduro/Trail bikes. The KORYAK 150 mm travel 34.9 mm seat post complements the 30.9 mm and 31.6 mm Koryak 150 mm DSPs already in the range and is designed for riders looking to build a new dream bike or up-spec their current bike. Both new dropper posts come with a serviceable Alloy cartridge.
  11. Press Release The launch of SHIMANO’s new e-bike system, known as SHIMANO EP8, brings the two pillars of e-biking - the hardware and the software – up to a new benchmark in system-engineered e-bike components that can tackle everything from premium mountain biking and competition racing to trail riding, cross-country, casual MTB, trekking and off-road adventuring.

  12. Shimano's second generation e-MTB system is packed full of new features designed to bring EP8's performance standard to the best ever seen in Shimano's e-biking history. Many of the unique features of SHIMANO EP8 come in its more powerful yet lighter weight, smoother pedaling, cleanly integrated and reduced-noise drive unit, which also manages to keep cool more efficiently and provide improved bike handling over its predecessors. As well as this two revamped mobile apps – the E-TUBE PROJECT app and the E-TUBE RIDE app – give riders more display options and more customizable control over their drive unit’s characteristics. The new system follows SHIMANO's long-standing e-biking principles of creating a natural feeling ride with controllable high power when you need it most, wrapped up in a total SHIMANO system package. From the e-bike drive unit to the drivetrain and brakes, it’s the performance level you expect from a brand with almost unrivalled experience in mountain biking. EP8 HARDWARE Drive unit The new EP8 drive unit (DU-EP800) is capable of pumping out 85Nm of torque to conquer the toughest trails and steepest climbs. This 21% increase in power over its SHIMANO STEPS E8000 predecessor comes along with a 300g weight decrease to 2.6kg (10% reduction) thanks to a new magnesium drive unit casing. This low weight and high peak power makes it one of the best-in-class drive units in terms of power-to-weight. The increase in power-to-weight is also complimented by an improvement in battery efficiency. The drag (the friction that comes with a pedal rotation, noticeable in particular when operating the system without power) has been reduced by 36% (vs. E8000) thanks to an updated seal structure and optimized gear design. This friction reduction creates improved battery efficiency when the motor is active, or a smoother ride when pedaling without support (ie when the motor is switched off or when riding above 25 km/h). Together with the friction-reduction is an improved clutch mechanism which provides a smoother cut-off when pedaling above 25km/h. That increased torque is also not at the detriment of noise. In fact quite the opposite, the new EP8 drive unit is quieter, operating at the same level as E7000, so you can cut the distractions and focus on the trail. Added to that, the smaller magnesium drive unit shell features improved heat-conducting properties with redesigned internals (optimized gear structure and new EW-SD300 wires) to aid cooling and improve performance when operating at maximum torque on long, steep climbs. The drive unit case is also shaped more in line with the smooth lines and angles of bike frames which improves ground clearance and, together with internal batteries, makes SHIMANO EP8-equipped bikes impressively sleek packages. All of these factors combine to provide natural and refined power delivery from a lighter, quieter, more compact and more powerful motor with less pedaling drag and a 20% increase in range. Technical features: The EP8 drive unit runs with a 177mm Q-factor) and comes with its own dedicated cranks which are available in a new 160 mm length (also 165/170/175 mm). The system will typically be spec’d with SHIMANO’s new XTR/XT/SLX/Deore 12 speed drivetrain with Dynamic Chain Engagement+ (12 speed) and three chainring options (34T/36T/38T). DU-EP800 uses the same frame mount pattern as DU-E8000 and DU-7000 meaning manufacturers can use the same frame design between multiple SHIMANO drive unit models. SHIMANO EP8 is also compatible with mechanical shifting (9/10/11/12-speed) gear systems, Di2 (11-speed) systems and internal hub gear (11/8/7/5-speed) systems. In particular EP8 is fully compatible with the recently introduced NEXUS Inter-5 making high power Shimano internal hub gear City & Trekking bikes a true reality. A new chain device (CD-EM800) is also available. The new mud-shedding design provides additional chain managemnt and is compatible with 11-speed and 12-speed SHIMANO STEPS set ups running 56.5mm or 53mm chain lines thanks to an adjustable space between the guide and chain. The system can be turned on via buttons on the computer, the battery, or an in-frame button (EW-SW300) usually located on the top tube. Handlebar controls: Computer and switch The EP8 computer display (SC-EM800) shares many external similarities with the highly-praised E8000 computer display, but with a new feature allowing riders to switch between customisable profiles. It has a 1.6” colour screen, readable in bright sunshine, with a compact and low-profile body to suit demanding mountain biking trail conditions.The SC-EM800 computer communicates wirelessly with SHIMANO’s E-TUBE PROJECT app via Bluetooth allowing riders to change drive unit characteristics on the fly. The SC-EM800 can also communicate with 3rd party cycle computers via ANT to display gear and battery information. To operate the drive unit riders can use EP8's new drive unit assistance switch, SW-EM800-L. This allows riders to toggle between ‘Off’, ‘Eco’, ‘Trail’ and ‘Boost’ support modes plus Walk Assist mode. The switch has an improved shape featuring concave buttons with wider input area to make them easier to push and control. The switch comes in SHIMANO’s I-spec design standard making it compatible with the dropper post levers (eg SHIMANO’s SL-MT800-IL). Alternatively the drive unit assistance switch can be removed completely if riders prefer to change support modes via their EW-EN100 toggle switch. However, removing the switch completely removes the possibility for the very handy Walk Assist feature found on all SHIMANO STEPS systems. This has been updated for EP8 Mechanical systems to create an intelligent Walk Assist mode, which means riders can hop off and walk their bikes with assistance from the drive unit. A double push of the drive unit assistance switch causes the pedals to turn and the bike to move forwards at 4km/h, regardless of which gear the bike is in. Batteries The battery options include the new batteries SHIMANO released in May 2020, the two 630Wh batteries, the downtube BT-E8016 and the internal BT-E8036 battery, or the smaller but faster charging 504Wh internal battery, the BT-E8035-L. Like their predecessors, all SHIMANO STEPS batteries are extremely long-lasting, taking up to 1000 full charge cycles before they drop to 60% of their original capacity, which in many cases is longer than the average ownership of a bike. EP8 SOFTWARE Refinements to EP8’s software is the other half of SHIMANO’s formula for a more natural feeling e-mountain bike. That has been achieved through adjustments to the way the three support levels perform, along with the customizability of those modes.BOOST mode now tops out at 85Nm of torque, reached with low rider input torque. TRAIL mode also tops out at 85Nm but it is also more responsive to a rider’s inputs, either saving battery at low input torques or quickly ramping up the power delivery to provide the maximum 85Nm output at approximately 60Nm of input torque. This is much sooner than its predecessor and it’s this smarter assist ratio algorithm that makes TRAIL mode so versatile that mode switching can, for the most part, be forgotten about. ECO mode tops out at 30Nm, reached in a similarly responsive manner. Aside from increased riding range, ECO mode of course can be used for riders to get a workout when they want it. What's more, all of this is highly customisable, both at home or on the fly via the E-TUBE PROJECT app, giving riders greater control over how and where they ride. BOOST, TRAIL and ECO modes can be customised with 10 different levels, the torque can be set anywhere between 20-85Nm, there are five levels of start assistance available, and these can be set for different rider profiles for different types of rides (eg high-performance/extreme riding, casual endurance ride, etc) or different riders. All of this information can be saved as preferences in rider profiles, for example a battery-saving commute mode and high-power technical singletrack climbing mode, and riders can easily switch between these modes via the computer display Meanwhile an updated E-TUBE RIDE app can be used by e-bike riders to monitor all their riding information in a smart phone display. Screen display options shows riding metrics in ECO, TRAIL and BOOST modes plus newly added functions including ride history, live maps and user-friendly graphical updates.
  13. Shimano today releases its latest 12-speed MTB groupset, the SHIMANO DEORE M6100 series, alongside new 11-speed SHIMANO DEORE M5100 and 10-speed SHIMANO DEORE M4100 versions to bring premium technologies to a new price level. The M6100 series is moulded from the same DNA the top tier XTR, SHIMANO DEORE XT and SLX mountain biking groupsets and is fully compatible with its more progressive companions so you can pick your favourite setup to match your riding needs. Meanwhile the 11-speed and 10-speed versions build on SHIMANO DEORE’s mountain biking legacy, retaining technologies such as HG HYPERGLIDE shifting, 2-WAY RELEASE levers, SHIMANO SHADOW RD+ derailleurs and I-SPEC EV handlebar controls to broaden the versatility of this value-focused group. Shimano DEORE M6100 Series (12-speed) Shimano’s proven 12-speed technologies are inherent in every component at SHIMANO DEORE level. 1x12 Crankset: The SHIMANO DEORE 12-speed crankset (FC-M6100) with its sleek metallic colour shift design comes in single-only (1x12) configuration for drivetrain simplicity. It features the same DYNAMIC CHAIN ENGAGEMENT+ technology as XTR, SHIMANO DEORE XT and SLX cranksets which, with its narrow/wide tooth profile, provides the key to the improved chain retention, smoothness and quietness of the drivetrain. For secure and fast mounting of the chainring the crank is equipped with a direct mount system, making chainring changes a breeze. Options include the choice between 170mm or 175mm crank arm lengths, 30T or 32T chainrings (although there is full compatibility between smaller or larger chainrings at SLX, XT and XTR level), or the choice between three different Q-factors (stance widths), 172mm (for an O.L.D. of 142/148mm), 178mm (O.L.D. 148mm) or 181mm (O.L.D. 157mm). Two alternative non-series SHIMANO DEORE-level cranksets are also available, the FC-MT511-1 (30T, 32T) and the FC-MT510-1 (30T, 32T, 34T). See table below for a summary: Cassette & chain: The SHIMANO DEORE 12-speed MICROSPLINE cassette (CS-M6100) is made from 12 durable steel sprockets and comes in a 10-51T gear ratio. Complete with the unmatched shifting quality of HYPERGLIDE+ technology you can shift both up and down this cassette under load, making SHIMANO DEORE shifting smoother than ever before. The SHIMANO DEORE 12-speed HG chain (CN-M6100) offers a smooth transmission with strong chain retention by extended portions on the end of inner chain plates to combine perfectly with DYNAMIC CHAIN ENGAGEMENT+ front chainrings and HYPERGLIDE+ cassettes to let you pedal continuously, even whilst changing gear under load. Rear derailleur: The 12-speed SHIMANO DEORE rear derailleur (RD-M6100-SGS) enables precise and quick shifting within the 10-51T range. 13-tooth pulley wheels and SHIMANO SHADOW RD+ technology reduces chain chatter and gives you improved chain retention thanks to a stiffer derailleur arm and higher chain tension. Shifter: The SHIMANO DEORE 12-speed right-side shifter (SL-M6100-IR) benefits from the same technologies as XTR, SHIMANO DEORE XT and SLX; I-SPEC EV. This offers you greater ergonomic adjustments like 14mm lateral movement and 10 degrees rotational movement so you can tailor your handlebar controls much more to your liking. Together with the speed of RAPIDFIRE PLUS and a 2-WAY RELEASE feature you can shift up and down the 12 gears of your cassette faster than ever before. Brakes: The SHIMANO DEORE M6100 brakes come in either an XC-specific two piston caliper (BR-M6100) or the trail/enduro four piston variant (BR-M6120), both with a redesigned brake lever (BL-M6100) resulting in a stiffer mount for better feedback and more power. The brake levers are equipped with Shimano’s proven SERVO WAVE technology which results in quicker pad/rotor engagement, improved power and a shorter free stroke. Both calipers can be used with resin or metal pads and are best used with the SM-RT64 or SM-RT54 rotors. Completing the cockpit is an optional seat post lever, the SL-MT500. This allows riders to quickly operate the seat post without sacrificing their hand position on the grip. The SL-MT500 seat post lever comes either in a clamp band or I-SPEC EV variation for a neater handlebar set up. Shimano DEORE M5100 Series (11-SPEED) And M4100 Series (10-SPEED) The retention of a 10-speed SHIMANO DEORE series and the addition of 11-speed SHIMANO DEORE expands the versatility of the SHIMANO DEORE name as a groupset to cover many different riding styles, preferences and budgets. Drivetrains: Unlike the 12-speed version, both series here retain a double drivetrain (2x11 or 2x10) option as well as single drivetrains (1x11 or 1x10). Gone are some of the advanced 12-speed shifting technologies but riders can still achieve great shifting performance with HG cassettes and HG chains, RAPIDFIRE PLUS MONO left hand shift levers and 2-WAY RELEASE performance. Riders choosing an 11-speed crankset will have the option of an 11-51T HG cassette with either a 30T or 32T single (1x11) drivetrain (FC-M5100), or a double (2x11) drivetrain in normal (FC-M5100-2) or Boost spacing (FC-M5100-B2) featuring 36T-26T chainrings and a close gear step 11-42T steel HG cassette (CS-M5100).10-speed riders can pair their 1x10 chainrings (30T or 32T) with a wide range 11-46T steel HG cassette or, for the 2x10 (36-26T) set up they can also choose the close gear step 11-42T steel HG cassette (CS-M4100). Derailleurs: Rear derailleurs are specific to your choice of drivetrain. The SHIMANO SHADOW RD+ RD-M5100-SGS rear derailleur is specific to 1x11 drivetrain chainlines and comes with a low-profile design to avoid damage from rocks plus a chain stabilizer to reduce chain drop and chain slap. It is designed to accommodate the lowest 51T gear on the 11-speed HG cassette. The RD-M5120-SGS rear derailleur also comes with the same SHIMANO SHADOW RD+ low profile and chain stabilizer and is designed for lowest sprockets of 42T (2x11/10-speed) or 46T (1x10-speed). A more affordable M4120-SGS SHIMANO SHADOW RD is also available for 2x11 or 2x10 drivetrains although it comes without the chain stabilizing function. Front derailleurs (FD-M5100/M4100) allow for smooth, quiet and light action front shifting with optimum tyre clearance (up to 2.3” on wide rims). Both options also come in multiple mount positions (D, E or M) to suit different frame designs. Shifters: Whether you choose a single or a double drivetrain the SHIMANO DEORE 10 and 11-speed shift levers (SL-M5100-IL/IR) come with I-SPEC EV positioning to give a simplified connection to brakes and dropper posts, allowing for cleaner handlebars (band-type clamps also available). On the left hand side of the bars the RAPIDFIRE PLUS MONO lever lets riders operate the front derailleur with a single thumb lever for both light and instantly responsive up and down shifting. Meanwhile the right hand side lever features an optical gear display for easily visible gear position. The lever features RAPIDFIRE PLUS speed to shift down three gears at a time whilst the 2-WAY RELEASE feature allows riders to quickly dump gears to approach climbs. Brakes: At 10 and 11-speeds there is one brake lever and two caliper types (2-piston or 4-piston) available. The BL-M4100 lever is compatible with 2-piston or 4-piston caliper designs. It features an additional handlebar contact point design for a stiffer feeling and comes with quicker brake engagement and a shorter free stroke than its predecessor. The BR-MT420 4-piston caliper provides powerful stopping power for resin or metal pads, whilst the BR-MT410 2-piston caliper provides a lighter weight option (resin pad only). Overview This chart quickly shows the single drivetrain and double drivetrain options available at SHIMANO DEORE M6100, M5100 and M4100 levels.

  15. Hi Hubbers!! Our 2019 Black Friday Sale kicked off today and will run until 29 November. New products are loaded daily so don't miss out! The link to the Black Friday page is here: https://www.evobikes.co.za/black-friday-sale.html
  16. Following a comprehensive research, testing and development process, bringing together global feedback from riders on trails, bridleways, pavement and paths at all levels of competitiveness, Shimano introduces a new component series known as GRX; the world’s first dedicated family of gravel/adventure components built for both fast riding and assured capability on loose surfaces. GRX offers RX800, RX600 or RX400-series components with 1x11, 2x11 and 2x10 drivetrains and mechanical and Di2 electronic shifting options, allowing riders to tailor their mixed surface riding experience and explore beyond their usual limits to pursue a wide range of terrain. Developing the series took Shimano’s development team well outside traditional confines to create a platform that addresses riders’ needs now and into the future. Be it gravel riding, modern adventure road riding, bikepacking, or fulfilling the needs of discerning cyclocross racers, SHIMANO GRX provides options ranging from gravel-tuned gearing ratios to custom ergonomics, from dropper post integration to gravel-specific GRX wheels with wider rim profiles. The components Diving into the detail, GRX includes three crankset options - 1x11, 2x11 or 2x10-speed – plus front and rear derailleurs, disc brake calipers with an in-line brake lever option, and left and right STI hydraulic levers, coming in either Di2 shifting or mechanical shifting options. These components employ Shimano’s class-leading drivetrain technologies from both the road and mountain bike side to deliver the hallmark shifting precision and stability for which the company is known. With GRX the net result is a smooth and quiet-running drivetrain that is specially tuned for the unique characteristics of gravel terrain, riding positions and gravel bicycle designs. For simplicity, Shimano GRX recommends using Shimano MTB (Deore XT, SLX or Deore) or Road (Ultegra, 105, Tiagra) cassettes and chains that already exist in the Shimano lineup. In addition to the category-leading Shimano GRX 800 series, there are also more affordable 11-speed components, a 600-series crank and set of shifters, which can be mixed seamlessly with 800-series parts, and 10-speed cranksets, derailleurs and shifter/brakesets. This means that you can create everything from a light-weight racing-level GRX stead at the premium level to a leisure-riding GRX workhorse at the more economical level. GRX Cranksets: The GRX cranksets are built for tackling different riding terrains and riding styles, all coming with a +2.5mm chainline for increased tire and frame clearance. GRX single ring cranksets offer the simplicity of shifting only on the rear cassette (options include RX800/600 40T cassettes or the RX800 42T cassette) and are delivered with Shimano’s Dynamic Chain Engagement tooth profile on the front chainring to offer increased chain retention over bumpy ground. Meanwhile the GRX double chainring RX810 crankset employs a 17-tooth gap which, at 48-31T, is the company’s widest-ever gear ratio. Together with the additional RX600-11/10 46-30T options, the double cranksets give big enough gear ratios for tackling the steepest climbs and pinning the steepest descents. GRX crankset weights: 1x11: FC-RX810-1: 655g (pictured), FC-RX600-1: 753g. 2x11: FC-RX810-2: 722g (pictured), FC-RX600-11: 816g, FC-RX600-10: 819g GRX Front derailleurs (FD): Complementing the cranksets, the Di2 (FD-RX815) or Mechanical (FD-RX810/RX400) front derailleurs are built with 2.5mm more outbound clearance for wider tires (up to 42mm) to cope with riding on rough roads. This means GRX front derailleurs must be combined with Shimano GRX +2.5mm cranksets. Both RX800-series mechanical and Di2 front derailleurs are built to accommodate Shimano’s widest 17T front chainring 48-31T gear ratio whilst the FD-RX400 10-speed derailleur accommodates the 16T chainrings found on the RX600 46-30T 10-speed cranksets. All front derailleurs provide Shimano’s legendary front shifting performance. Shimano Di2 FD’s can be perfectly adjusted using Shimano’s simple and integrated controls whilst mechanical FD’s bring an extremely light front shifting feeling with an ergonomic power curve, toggle link construction for more cable routing options and an integrated cable tension bolt for precise and easy adjustments. GRX front derailleur weights: FD-RX815-F: 131g (pictured), FD-RX810-F: 94g (pictured), FD-RX400: 95g GRX Rear derailleurs (RD): Adopting the technology introduced in 2018’s RX rear derailleur, the GRX Di2 RDs (RD-RX815/RX817) or mechanical RDs (RD-RX810/RX812/RX600) are designed for silent, smooth and reliable shifting on rough terrain with a chain stabilizing system known as SHADOW RD+ to manage ‘chain chatter’, minimize unnecessary derailleur arm movement and provide uninterrupted shifting performance. GRX comes with the choice of four derailleurs depending on which cassette and gear shifting operation you choose. Riders using an Ultegra, 105 or Tiagra level 11-30/34T cassette will need to use the short cage Di2 RD-RX815 or mechanical RD-RX810 rear derailleur, whilst riders choosing a Deore XT, SLX or Deore level 11-40/42 cassette will need to use the longer cage Di2 RD-RX817 or mechanical RD-RX812 RD, both of which come with a pull ratio similar to Shimano’s road derailleurs. GRX rear derailleur weights: Di2: RD-RX815/RD-RX817 (pictured): 288/322g. Mechanical: RD-RX810/RD-RX812 (pictured): 251/264g GRX STI levers: GRX shifting comes courtesy of dedicated gravel-specific ergonomic levers (Di2: ST-RX815 or Mechanical: ST-RX810/RX600/RX400, ST-RX810-LA) featuring an 18mm higher axis point, curved brake lever profile and anti-slip textured finish which can be gripped with assurance over rough terrain. To integrate the use of dropper posts in gravel riding, SHIMANO created the GRX mechanical ST-RX810-LA left hydraulic disc brake lever that, when used with a 1x11 drivetrain, can control a dropper post whilst also keeping the cockpit tidy. The integrated cable pulling system has a 9mm lever throw to operate dropper posts with cable heads at the shift lever. SHIMANO GRX also includes 1x11-specific RX800 and RX600-series left side hydraulic disc brake levers with no dropper or shift internals, including the 1x11 Di2 left-hand lever (ST-RX15), which comes with three buttons (two side buttons and a hood top button) for operating ancillary functions such as lights or 3rd party computers. GRX STI shift/brake lever weights: ST-RX815-L/R Di2: 565g, ST-RX810-LA Left side dropper post lever: TBDg, ST-RX600-L/R: 611g, ST-RX400-L/R (10-speed): 613g GRX Braking systems: A primary concern of gravel riders is having enough brake power to control speed on steep and sudden descents. That’s why, at the top tier of the GRX family, one variant of the RX800-series brake levers (ST-RX815) offer Servo Wave technology coming from Shimano’s mountain bike brakes. This provides a stronger braking feeling with greater modulation options for more aggressive riding. If you prefer the RX810 non-Servo Wave version, or the RX600 and RX400-series levers, they still provide an excellent level of disc brake stopping power, akin to Ultegra, 105 or Tiagra road disc brakes respectively. An additional braking option comes with an inline hydraulic sub-brake lever (BL-RX812-L/R) which connects to the main hydraulic line running to the front and/or the rear caliper. The sub-brake lever is designed to be mounted on the handlebar next to the stem offering options for braking when riding with hands on the tops. GRX hydraulic disc sub-brake lever weight: BL-RX812L/R: TBDg The GRX calipers (BR-RX810/400) echo the design of Shimano’s flatmount road calipers to deliver powerful brake performance, taking features like one-way bleeding and ICE TECHNOLOGIES heat-dissipating finned brake pads and rotors to offer efficient cooling and long-lasting brake performance. GRX calipers: BR-RX810: TBDg, BR-RX400: 143g Gravel-specific Wheelset: To complete the experience, Shimano tips its cap to the experimental spirit of gravel with two gravel/adventure-inspired 12mm E-THRU axle wheel sets (WH-RX570-TL-F12/R12). The 700c or 650b (non-Boost) tubeless-ready wheelsets offer an optimal balance between weight, stiffness and gravel durability, bringing a wider 21.6mm inner rim width (comparable with MTB XC wheels) and an off-set rim height of 22mm.GRX wheelsets: WH-RX570 700c: 1600g/pair, WH-RX570 650b: 1540g/pair Overall, with the multiple options and specifications available, GRX has a broad appeal and a broad message to riders of all disciplines.
  17. Hi all, In my attempts to bleed the rear brake, I managed to strip/round the 2mm (hex) head of the bleed screw (Y0C698030) on my shimano ultegra shifter. It turns out (reading online reports) this screw is made of a rather soft metal compound and is quite easy to damage. Now the mission is to locate a replacement in south africa; spoke to a coolheat agent - not only do they not have stock but they've never ordered this part before. 6 months lead time LOL! 2 questions: where else can I can get this elusive part in SA? The shimano manual recommends 0.5Nm - 0.7Nm to tighten this screw. My torque wrench starts at 2Nm. Where can I purchase such a TW in SA? I saw a Gedore brand item on a UK site...Thanks for any tips. Geoff.
  18. Hello hubbers, My bike, Scott Genius 750 (2018), has the ability to switch between 27"+ and 29", and now I'm interested to do exactly that. The reason is mainly because my bike has quite a low BB, and I believe 29er will be able to just add a few needed centimeters. I just want to know if it's possible to trade my current 27"+ wheelsets for 29ers? I have the following: Rims: Syncros X-30s, 32 hole, 30mm Hubs: Front - Shimano HB-M6010-B CL, 15x110mm Rear - Shimano FH-M6010 CL, 12x148mm Tires: Maxxis Recon 2.8" I also have a Shimano CS-HG50-10 speed cassette, which I believe is not compatible with Sram XD hubs, but in the future I'd probably want to upgrade to Sram SX/NX and I don't know if XD hubs and Shimano cassetes are compatible for the time being? What can I expect to get for my wheelset aswell? Thanks in advance!
  19. Hi Hubbers, I hope someone can help me here. My sons bike is giving me some headaches with the gears and the dealer where i bought it cant seem to help me. So the chain broke so I took it in to get a new one but every time you change gears from the small chain ring to the middle chain ring it is as if it doesn't release the chain ( See Pic) so I think that it has been doing this for some time and this caused the chain to snap. Also the bike did not do 300km since I bought it new.
  20. Hi Hubbers! Our LE TOUR SALE is now in full swing! New products are added daily. Head over to https://www.evobikes.co.za/le-tour.html to see what is on sale!
  21. Hi, sorry if this has been asked before...I did search and could not find any posts on this on the site. So if its discussed elsewhere, please direct me there... Anyway, on to the question: I have been sitting on the fence for long enough to have look at whether this 1x12 thing SRAM started was gonna turn out to be a fad, but then Shimano joined the fray and I think I may be getting to the point where I am convinced there are merits for me to move from 2x11 to 1x12. What would I need to be able to go from 2x11 XT to 1x12 (either SRAM or Shimano)? I have heard that I would need to change to a XD driver body for SRAM (not that I actually really know what that means???) and I assume I would need to do somethin gsimilar for Shimano 1x12. Does changing a driver body mean also a new hub (i.e. a complete wheel rebuild)? I also know that there are aftermarket etsups or conversion kits, but I only want advice on what I need to do to go from Shimano to SHimao or Shimano to SRAM fully OEM and without "'n Boere plan". Thanks in advance...

Shifters: With side adjustment and rotational adjustment options the ISPEC-EV shifters, which bolt neatly to the brake lever, offer solutions for tailoring the riding feel. For riders using a 2x12 set-up, a MONO lever (SL-M7100-IL) on the left shifts the front derailleur both up and down with an extremely light and precise action. SLX M7100 shifters are also available in a clamp band version. Shifter weights: SL-M7100-IR: 121g, SL-M7100-IL: 73g. Brakes: SLX brakes calipers are available in an XC-specific 2-piston version or a Trail/Enduro 4-piston version.The 2-piston version shares the same design as the previous version, which means the previous SLX-level G02S/J02A resin brake pads or G04S/J04C metal pads brake pads are compatible, whereas the 4-piston version is a new completely new construction drawn from the XTR M9100 design, using D03S (resin) or D02S (metal) brake pads pad (compatible also with N03A and NO4C finned pads). The SLX brake levers work with both the XC and Trail/Enduro calipers and come equipped with Shimano’s Servo wave system for quicker engagement, improved power and a shorter free stroke. The brake levers are now angled in two positions against the handlebar for a stiffer brake sensation. The levers also feature a reach adjust dial for simple brake tune-ups on the trail. XC style brake kits (BR-M7100-BL-M7100) with rotors (160 mm SM-RT70) and brake pads weigh 425g and the Enduro style brake kits (BR-M7120-BL-M7100) weigh 444g including rotors and pads. Rotors: The SLX-level ICE TECHNOLOGIES rotors (SM-RT70) are designed to cool rapidly thanks to a sandwiched aluminum core, fused in a durable steel outer layer, resulting in consistent brake performance and longer lasting brake pads. Sizes available are 140mm (121g), 160mm (133g), 180mm (159g) and 203mm (193g). Hubs: Individual SLX front hubs and rear FREEHUBs are available in widths of 100mm and 142mm, 110mm and 148mm, or 157mm. The freehub (FH-M7110) features a cassette body with Shimano’s MICRO SPLINE design. Hub weights: HB-M7110: 142g, HB-M7110-B: 147g, FH-M7110: 350g, FH-M7110-B: 354g, FH-M7130-B: 359g. Main SLX differences to DEORE XT:No free stroke adjust on brake lever One aluminium cassette sprocket Less chainring options No complete wheels No multi release on right shifter No textured padding on either shift levers SIL-TEC coating on chain roller link plates No FREEZA technology on rotors 148g difference to XT in like-for-like specification
  23. New DUAL CONTROL (brake/gear) LEVERS (ST-4720-L/R) replace the previous non-series ST-RS405 units and now follow the pattern set by Dura-Ace, Ultegra and 105 with a slim body to house the hydraulic disc brake controls and increased adjustability for optimum bike control. The TIAGRA 10-speed shifting mechanism within the lever body has also been upgraded from the non-series levers to provide quicker rear gear shifts, allowing riders to rifle through the cassette to gear up for a sprint or gear down for a climb. An optional extra feature with the new TIAGRA Dual Control Levers, also found at 105 and Ultegra levels, is a version with a short reach lever and more outboard profile (ST-4725-L/R) for riders with smaller hands, creating a more tailored and confidence-inspiring riding experience. Meanwhile, a lower 48-34T front chainring combination for the TIAGRA FC-4700 2-piece crankset now appears alongside the existing 52-36T and 50-34T cranksets. This smaller ratio closes the gap to 14T between the big ring and small ring, reducing the number of compensation shifts needed in the rear cassette and making TIAGRA more in line with a wider number of riders. Finally, a new 12mm E-THRU hubset (HB-RS470/FH-RS470) for disc brakes appears at TIAGRA level. When combined with compatible frames, thru-axles increase the rigidity of the wheel and allow for more accurate alignment of disc brakes. This 10 or 11-speed hubset is available for 28H or 32H rims and comes with a disc brake-specific O.L.D. of 110 and 142mm respectively.
  24. Does anyone know where i can find some of these locally for 24mm cranks? I see Token also makes some red Alu ones I installed a Praxis PF30 converter BB for Shimano cranks into a new frame and obviously PF30's don't take spacers like a threaded ones do . I just need to move the drive side out by about 2mm to centre the cranks in the frame. It is pushing my pseudo-OCD next level. Please see the pics attached. Anyone that can point me into the right direction? or where i can have some made even? EDIT:Regarding chainline...i'm good still at 50mm so 2mm extra wont hurt in the boost frame. 2mm will put me smack bang in the middle of a 10 speed cassette in the rear. thanks in advance. Morné
