    Hi Hubbers I recently took on a (fun) personal project of finding an alternative to the commercially available cover plates used to cover up the frame mounting space left when removing the high direct mount front derailleur for a 1x conversion. After searching the interwebs I cottoned onto a 3D printed plate through options and ideas from Shapeways and the MTBR forums. Shipping for the Shapeways product made it unreasonably expensive for what it is ($6 for the plastic plate, $20 for shipping), so I contacted a few 3D printing companies in Cape Town to see if someone could help me out. And success! I managed to find someone! Following a bit of trial and error with my design I ended up with a plate that I am pretty stoked with!! I have customised it for my Pyga and I think it looks pretty rad! The finish of a 3D print is not the smoothest, but it's hardly noticeable when viewed from a short distance. Best part is it cost a fraction of anything else out there, amped Thoughts on the outcome are welcome and I'm happy to try help anyone out who would be interested in doing the same for their 1x conversion. By this I mean I can either share my 3D file with you (if you can access a 3D printer) or look at getting plates printed through my own source (limited to black or white) and then take it from there. I assume the design would be a universal fit, but have only managed to test it out on the Pyga frame so far. Given that it is also a very recent addition to my bike I have no idea of durability of the part and how it will stand up to the elements (it's made from ABS plastic) but will post future updates here. Fingers crossed it will have some longevity! Overall though I think the project was a success, win!

    Hi, I want to upgrade my 3x drivetrain to 1x. I want to take my bike to a bikeshop and ask them for advice on how to go about doing it as I tried reading about it but there are to many things to understand. I assume it will cost a penny so I also want to know what cost I'm in for. Any advice on which bikeshop I can go to in Cape Town where i can get proper advice and the most cost effective way of doing it. Thanx

    Hey. I've just bought a 1x11 XT upgrade kit from CWC to replace my current 2x10 XT kit. I plan to run a 32 front blade and it's a 11-42 cassette. The upgrade kit comes with a long-cage RD (SGS), but I think I'd prefer a medium-cage RD (GS) to limit rock strikes and just to keep things a bit neater. Does anyone know of any issues or have any practical experience / advice running a medium-cage (GS) XT RD with a 32 blade and 11-42 cassette? Or should one stick with a SGS when running this set-up? Shot, Dave

    Hi Guys, I have a 32T chainring with 11-46 cassette on my softtail 26er (1x11 Shimano XT). I'm trying to decide between the exact same setup on my 29er hardtail vs the following: 30T with 11-42 cassette (also XT). Bottom line: I do a lot of climbing and I'm not an avid downhill rider. I feel the 32T with an 11-42 cassette might be tough on the steep hills. And the best priced upgrade kits I'm seeing on the hub are with the 11-42 cassette. Do you think the 30T option could be a good one (i.e. comparable to 32T with 11-46 cassette)? Thanks for your help

    Hi guys, Sorry for posting another topic on this issue but I'm still stuck. I'm looking for a press fit BB for my 26" Rocky Mountain. My frame's BB shell width is 83mm. I'm wanting to get the M7000 SLX crankset. But before I pull the trigger, I'd like to know whether there is a BB that will work for this upgrade. Ideally I'd like to purchase it off a local site, such as CWC or Evobikes etc. Thanks again for any assistance and apologies for posting a second topic. Cheers

    I've got a 1x10 setup with 32T upfront, XT rear derailleur, XT shifter, and a Praxis wide range cassette (11-40). I'm thinking of upgrading my current Shimano Deore crankset to the new SLX M7000 11 speed crankset with 32T. Basically, I can't afford a complete 11 speed upgrade right now so I'm just considering the crankset for the time being. My current one has seen better days. Is this possible? Cheers

    Hey Guys First thread on here so take it easy on me haha... I have a Cannondale Trail 29 Hardtail. Used to ride a bit of DH at varsity (I sucked, good at crashing though.) and then focused on paddling and running the last 8-10 years. I decided to get back onto a bike cos it's fun and you can do such a cool mix of long explorey days and cool techy trail rides. Anyway, I bought my budget Cannondale Hardtail with tubeless done and the front derailleur removed by the previous owner as he was just using it to keep miles off his fancy bike for beachfront rides etc. I got it for R 9 500 only a year old in immaculate shape. So its 1x10 SLX and has the Shimano branded but no specific name (SLX / Deore etc) brakes. I manage 95% of the time with the 1x10 as he put on a 40t big cog - spin out on the downs obviously but that's fine. 34t chainring. I've done close to 100km days pretty comfortably and I manage most of the steep tech stuff ok too. I think that 1x11 would obviously be better if I want to do some stage / longer 1 day races. The brakes are also adequate but not much more than that. What sort of price would I be able to pick up a SLX 11 speed rear derailleur and cassette and some better brakes? Happy to trawl the used section of the hub until I can find something! I've put on wider Ritchey bars and a shorter (50mm) stem as it's a large and I'm probably in between M and L frames. Do you think it's worthwhile? I'm happy and comfortable on my bike and riding some pretty decent distances / speeds and technical stuff so don't feel the need to go full sus any time soon due to extra cost and service requirements etc.

    Hi All, Looking to upgrade to 1x11 with an oval chainring.... My question is which OVAL chainring is best right now.... Csixx vs Absloute Black

    I have a confusing question... I'm looking at buying the new XT Di2, but... The new XT Di2 RD is only available as a GS (Medium Cage) and claims to have a max capacity of 35T, which seems normal for a GS RD. However, Shimano markets the XT Di2 as being both 1x11 and 2x11 capable. They say you can use the 11-46 cassette for the 1x11 and either the 11-42 or 11-40 for a 2x11 setup. From Shimano product page for RD-M8050-GS: Series : SHIMANO DEORE XTMaximum Sprocket : "42T(2x11-speed) 46T(1x11-speed)"Minimum Sprocket : 11TFront Difference : 10TTotal Capacity : 35THere's my dilemma. Even if one uses the new shimano 10 tooth difference crank (say 36/26) both the claimed 2x11 setups exceed the maximum capacity of the RD. Using the 11-40 cassette and the 36/26 chainrings (which needs less capacity than with the 42T cassette) this gives us a 10+29 needed total capacity of 39T. The school I went to thought me that 39>35. With a 42T cassette, the needed capacity climbs to 41T. So theoretically the XT Di2 RD won't handle the stated 2x11 setups based on the stated capacity. What am I missing? Do I need to get the SGS XTR Di2 RD for this to work as 2x11? Does this only apply to some programmed SynchroShift which manages the total capacity? So before you ask why not just do 1x11, my other bike is a 1x11, ... I like my short gear spacings for long rides (ex roadie) Any ideas? Anyone from Shimano care to shed some light on this?

    Hi Hubbers, I have been running my SRAM X0 (2X10) setup in the picture below. I've had a few setbacks and would like to move away from SRAM. Is it possible to retain the cranck in some way or form and purchace a XT1x11 groupset and marry the two without spending to much $? New xt crancks are expensive and there is not much wrong with the crank arms. Can anyone propose a product or two that I can use to retain the crank and run XT?
  16. AllAboutRides
    Hi there everyone! I want to upgrade my current mtb groupset and yes as always weight plays a big role. Currently running Shimano XT 1x11 and Simano XT brakes. Best way to upgrade? *XTR *XO1 *XX1 Please share thoughts and is it worth spending that extra money for better groupset?

    Need some help!!! Trolled the net to death, but not able to figure out the differences between the 1x11 and 2x11 SRAM GX rear derailleurs? Yes you get two versions, never expected it: https://www.sram.com/sram/mountain/family/gx http://www.chainreactioncycles.com/za/en/sram-gx-1x11-speed-rear-mech/rp-prod135897 http://www.chainreactioncycles.com/za/en/sram-gx-2x11-speed-rear-mech/rp-prod135898 After looking at the SRAM tech docs, it seems that the 1x11 is only avail in a long cage version that makes sense, but apart from that, what is the real world differences, will a 1x11 unit work on a 2x11 setup. As I see it , it is as easy as the rear derailleur should just be able to shift 11 gears. Shimano only has one 11sp Xt derailleur, why does Sram need 2? Looking at GX 2x11 crank + 104bcd single chain ring, 2x11 front derailleur, XT 11-42 cassette (due to XD driver), xt chain, SRAM GX shifters, but the rear derailleur is the Q? The above will enable me to experiment with a 1x11 setup and still be able to change over to a 2x11 setup for the days that you start at the back and need to work your way thru the walkers on the hills, or help to get to the end of the TransBaviaans.

    The simplicity of a one-by chain ring setup has always appealed to me. Less cockpit clutter, no chain suck and, for the weight-weenie in me, some grams lost. When the Kitted Wonder Ring arrived for testing I decided to take the plunge and convert my own steed to 1x10. Click here to view the article

    So I havent been cycling at all this year because of travelling and a new job and today it hit me big time I miss cycling Tooo much so I will have to get back in the saddle, but leaving behind my Silverback storm which I changed to 1x10 and loved I wondered what the feedback is on XX1 and if people do like it. (I may want to build a new bike with it) Also what is the life expectancy on regular use on a cassette. The wolft tooth I had was really good on lasted a long time. Also whats the thoughts on the Shimano 1X11 version? I am itching for a build.....

    I am in the process of replacing chain, cassette, chainring on XX1 and it is damn expensive vs XX (using XT cassette and XT Chain). Any other worth while options that I can consider to make the maintenance cost cheaper on the 1x11 setup (wolftooth, XG1180 cassette, KMC chain)? I bought the bike second hand and the parts were already worn, original owner did not change the chain, so it was unfortunately to late for just a chain swop. Can any of you XX1 riders give me a prediction on the lifespan of an XX1 cassette if I do a regular chain swap?

    Hi Guy's Decided going the specialized route and looking at these two options. Marathon has nice group set and comes with swat included as well as two cages. WC is 1x11 which I quite like for simplicity but not sure if I will miss the 2X 10 combo. Getting back into cycling after two year break and need to build fitness from start again.(big accident) Intentions to ride trails and longer events with stage races about twice a year. Opinions and advice greatly appreciated. WC is slightly cheaper than Marathon.

    An interesting read: Shimano’s Shifting Philosophy We were given a fresh explanation of Shimano’s drivetrain philosophy at the launch, which actually made sense. Shimano divides all available gear ratios into two groups: “Driving gears” and “Challenge gears.” Driving gears, in the case of a two-by or three-by transmission, are in the middle range of the cassette when the rider is in the big chainring. Challenge gears are for the steepest climbs, when the rider is forced to select the smaller chainrings and to use the larger three cogs of the cassette. In the case of a one-by drivetrain, Driving gears are the first eight cogs on the right-side of the cassette. Shimano professes that the smooth, 10-RPM jumps between shifts generated by its Rhythm Step, 11 by 40-tooth cassette, optimize the efficiency of the driving gears that we use most often for both climbing and pedaling on the flats. While the closer gear ratios of Shimano’s XTR cassette provide smaller steps between most of the gearing range, they cannot attain the higher top and bottom gears of SRAM’s XX1 10 by 42 cassette. To achieve a competitive spread, Shimano “strongly suggests” that XTR customers choose its two-chainring option. Before you whip out your calculators, the closest comparison that a Shimano XTR M9000 two-by drivetrain has to SRAM’s one-by is: Shimano 28 x 38-tooth chainrings, two-by drivetrain: Lowest gear 28/40 = 1.42:1 ratio. Highest gear 38/11 = 1:3.45 ratio. (22 gear selections) SRAM 30-tooth chainring, one-by drivetrain: Lowest gear 30/42 = 1.4:1 ratio. Highest gear 30/10 = 1:3 ratio. (11 gear selections) What the above chart demonstrates is how Shimano’s close-ratio two-by option provides a nearly identical gearing spread when compared to a SRAM XX1 one-by drivetrain. By switching to a 28-tooth chainring, the SRAM one-by drivetrain can also match Shimano’s 26 by 36 option, but Shimano also offers a third, 26 by 36 option for its two-by crankset that provides XTR customers a lower granny gear than SRAM can match (Shimano: Lowest gear 24/40 = 1.66:1 vs SRAM: Lowest gear 28/42 – 1.5:1). The bottom line is that Shimano’s choice for trail gearing is a two-by transmission, and it competes directly with SRAM’s one-by offerings. The customer’s choice is: “Do I want 22 shifts and a front derailleur, or do I want 11 shifts and no front derailleur?” What about Shimano’s One-By XTR Option? One-by customers can choose XTR chainrings between 30 and 36 teeth, but the narrower gearing spread of the 11 x 40, eleven-speed cassette means that riders may need to keep a couple of chainrings in their toolbox to match their gearing to the task at hand. Calculating out Shimano XTR’s lowest-available, 30-tooth-chainring option fetches a low gear of 1.33:1 and a high of 1: 2.73. Compare those figures with the options from SRAM and Shimano that we covered earlier in this segment, and they indicate that hills will be harder to climb, or you will probably be spun out on the flats. Shimano’s one-by gearing options are clearly intended for racers and stronger riders who will probably choose the biggest chainring that they can comfortably push and then suffer with whatever low gear is left when the big climbs arrive. What this says, and its from Shimano themselves, is that their "One-By XTR " option is not anywhere near what SRAM can offer. The 10 x 42 option with SRAM makes more sense vs 11 x 40 from Shimano....unless you like suffering!! this tells me that SRAM is the only option for a single chainring as their spread is better. Shimano still needs two up front or you buy extra Chain rings to swop out if the ride is challenging

Shimano’s one-by gearing options are clearly intended for racers and stronger riders who will probably choose the biggest chainring that they can comfortably push and then suffer with whatever low gear is left when the big climbs arrive. What this says, and its from Shimano themselves, is that their "One-By XTR " option is not anywhere near what SRAM can offer. The 10 x 42 option with SRAM makes more sense vs 11 x 40 from Shimano....unless you like suffering!! this tells me that SRAM is the only option for a single chainring as their spread is better. Shimano still needs two up front or you buy extra Chain rings to swop out if the ride is challenging

    Had a really long day at Ironman this year... 5 years of bike hassles in 180kms.... Best be forgotten Nonetheless - this got me thinking. Why does no-one ride a 1-11 setup on a TT bike? Answers to my own questions would be: minimal weight saving (Cabling, derailleur, chainring, shifter etc...dont add up to much) Any weight saving would be reduced by having to add a chain guide Gap between gears is too large. Optimal cadence is in a very narrow range of maybe 5 rpm (not sure what Sheldon Brown says about this) My situation further compounded by running Osymmetric (not Rotor etc...) front rings. Thoughts?

    I have been invited to ride S2S in 2015. I currently Ride a 2 x 10 XT setup with a 38 / 24 front and 36 / 11 Rear. Bike is a BMC TE02 and Medium hard tail. I am upgrading my frame to a BMC TE01 and as my current drivetrain is worn I am looking to change to XTR 2x10 or XX1 1x11. I am 181 cm tall, 83 kg. 39 years old. I am a fit rider as confirmed by VO2 max testing done at the Prime institute in Durban. I race XC marathon and I am competitive in my age category. As far a technical ability I can ride the trails at Karkloof (the difficult options) with my XC Hard tail setup. I am very comfortable on the 2x 10 but the 1x 11 has undeniable advantages. I am going to be racing Sani and have never ridden it so would appreciate any info that you guys could give me. I am obviously concerned of not having a low enough gear for really steep climbs, I also don't want to spin the hell out of my legs to go any where. What can you tell me.... Thanks Ryan
