  1. Yep....gear gaps but 1x has so many advantages and some newer frames give you no option. It can't be all that hard to make a 2x or 3x rear hub 'transfer box' . This would be a planetary gearbox/freehub combo that would replace the freehub and sit inside the space under the cassette so it can retrofit to existing hubs and wheel standards. Obviously it would be larger diameter than existing freehubs. If one of the ratios is an overdrive, this removes the need for small, inefficient, fast wearing cogs in the 10t to 15t range and frees up some space under the cassette for the mechanism. A second actuating cable would likely be needed but so what. Sent from my SM-G900F using Tapatalk
  2. Reviewer has a bike with CTD suspension, avoids the climb setting on rear shock and then criticises climbing performance .... I maintain a pair of these for friends and they are great bikes for the price. The CTD Performance fork has the FIT damper not the open bath CTD that was so disastrous on the Evolution Series so it works well but had the same stiffness problem mentioned in the review. Found almost no oil in it when doing the first lowers service Changing the bath oil to 20ml Fox Gold each side and tweaking the air pressure / damping to suit the rider's weight sorted all that completely. Happy owners. Strange choice on that particular model to spec SLX shifters with XT derailers. The other way around would shift better. Also, the cassette is SLX and not ideal for conversion to wide range 10spd if you go 1x because the 15t and 17t can't be removed. Sent from my SM-G900F using Tapatalk
  3. I wasn't referring to the bike Myles....Craig82 contemplated sacrificing a body part for one. I was wondering if his personal attachment was clouding his judgement regarding the market value of the jewel in question ...... Sent from my SM-G900F using Tapatalk

  5. Reverb Stealth fitted on my TBLT purchased April 2014. Started getting spongy a few months in. Had it bled, marginal improvement and replaced with a new one under warranty at about 6 months. The replacement was fine for about 9 months but sucked a little air in at some stage after that (lifting by seat or hanging by seat on a rack). Useable but difficult to actuate and slight vertical play. Had it serviced 6 months ago (R1100) and now better than it has ever been. Moral of story - do not (ever) lift or hang the bike from the saddle. The RS literature does not tell you this. Reverbs can apparently suck air into the piston/cylinder assembly if the post is placed under tension. Then the issues begin. 2nd big issue - the standard service kit does not include a replacement piston head ( or some such part) and this is apparently the fastest wearing component according to my LBS - the replacement piston heads are ordered separately and quite expensive .

  6. Purpose of the reamer is a) to make sure the plug will fit and b) to precoat the hole with glue before inserting the plug. The Sahmurai seems to forego the glue bit. Sent from my SM-G900F using Tapatalk
  7. Yeah......and the top guys average well over the 25km/h assistance limit on XC courses so even a fit rider on one of these is not going to challenge for a podium, given that it is at least 10kg heavier than a nice trail bike. Sent from my SM-G900F using Tapatalk
  8. I doesn't move unless you pedal it. Even at maximum assistance I doubt it can put out the wattage that a competitive cyclist would. There is also a low max. speed of about 25km/h beyond which no assistance is given. This is not a trail ripper. It reads the torque you apply to the crank and adds 30% to 100% of that, governed obviously by its own limitations. So at most, it will match the rider's input....providing up to 50% of the total going to the back wheel. As I see it, this bike will help you to climb but you're on your own power at any appreciable speed. Sent from my SM-G900F using Tapatalk
  9. The competition laws are about ensuring fair competition between competing brands. Nothing wrong with e.g. Toyota SA setting a pricing structure for its dealers. But if Toyota made a deal with all the other bakkie suppliers to fix prices and carve up the marketplace into zones............ Sent from my SM-G900F using Tapatalk
  10. Did some training on the competition rules and regs a few years back. The range of seemingly innocent activities that you should not engage in was an eye-opener. For example : You are at a trade conference and an old friend who works for a competitor walks past...you are not supposed to even talk to him, let alone have lunch or heaven forbid, discuss sales figures..... As for attending a meeting, regardless of the topic, just being in a room with a bunch of competitors automatically makes you guilty, even if you never said a word.

  11. Call it 'sweeper class'. They start after the kiddies ride and clean all the litter and tape from the course..... Sent from my SM-G900F using Tapatalk
  12. I could see myself sessioning Renee's Rumble and Bat Outta Hell all day on one these. They need to add regenerative braking to extend battery life. This would need some sort of sensor on the brake levers or a pressure transmitter on the brake lines to trigger it by keepi ng the drivetrain clutches locked in when the brakes are activated.

  13. I think 27.5 plus will be great for the Kzn coastal guys who ride and train in the sandy trails of local plantations and sugar cane fields. Reckon it would handle wet beach sand at low tide quite well too. Gonna get horribly heavy in mud.... Sent from my SM-G900F using Tapatalk
  14. With you on all points there. My post was not directed personally at you. Sent from my SM-G900F using Tapatalk
  15. All should be aware that Ezemvelo KZN Wildlife manages the park and most of it is a world heritage site. Some areas are declared wilderness. All this means that international treaties are in place and govern, to some extent, the activities that may take place there. Loss of world heritage status, for example, would be detrimental to local tourism businesses. At present very little MTB is permitted within park boundaries managed by Ezemvelo. As far as I know, only Mike's Pass and the old forestry jeeptracks are permitted. Some resorts and hotels have very tame short trails too. There is room for some development of mtb but please lets not have the massive over-utilisation and erosion caused by skiing, hiking and mtb in some parts of the world (dare I mention Morzine and surrounds?). I would be much in support of a responsible attitude to development and for this to be done in consultation with the authorities. From contacts I have, belive me that we are a hair's breadth from an outright ban on mtb in the park because many have pushed the boundaries and not stuck to permitted trails in the past. Please don't be the box that wrecks it for all of us. If you really must adventure in the mountains with your bike then Lesotho is far less regulated and has much more rideable terrain than the Little 'Berg region referred in this thread. One of those pilots mentioned has already trashed at least 1 chopper in the mountains and I have witnessed his approach to flying at altitude 1st hand. As a long time hiker, climber and mtb'er with extensive knowledge and experience of the Drakensberg I am happy to debate some of the issues mentioned here if they seem a bit controversial to you. Yes we would all like to see mtb access improved but understand that this environment is very sensitive and critically important to the water supply of KZN. There are many forces at play and access will have to be negotiated carefully to avoid a hardening of attitude by authorities who have limited budget for developing and monitoring a new activity. It is easier for them to just say no. Sent from my SM-G900F using Tapatalk
  16. I have an idea the bolt is alloy and the bearing obviously steel. With a little water getting in corrosion may have occurred and the corrosion products build up in the joint making it very difficult to remove. It will be difficult to heat the bolt and bearing differentially but you could try this: 1) heat the bolt and bearing up to around 180 degC in an oven. Grease in the bearing may smoke or burn. 2) remove from the oven using pliers to hold the bearing. 3) touch either the head or end of the bolt to a piece of ice for a few seconds to cool the bolt 4) try to hammer or press the bolt out again Sent from my SM-G900F using Tapatalk

    Dopers suck

    Agree with this approach. A sporting federation can only ban future participation of cheaters. The ban should be proportional to the severity of the offense. However, these offenses need to also be seen as fraudulent activity, especially when unfair acquisition of winnings and sponsorships is involved. I agree also that the offender should pay back all benefits and costs. But when the ban, reparations and any criminal sentence is served....he/she can come back and race....and should expect to be monitored very closely....and some cold shoulder....and maybe some sledging.....

  18. If they are pre-assembled and the hoses not too long then it is a simple bolt on job. But if you need to shorten hoses or route internally through the frame then you'll need to disconnect hose and bleed after. Not sure what you're expecting. M615 to M675 is not going to give a significant performance upgrade unless the old brakes are poked. M615 are good reliable brakes but the SLX brakes will be lighter and a bit more adjustable.

  19. Those checkers tend to overestimate the chain wear. If it indicates wear by dropping in then remove chain and measure by hand for an accurate result. The chain checkers are only good for a quick screening test. I have one too. Mine reads 0.5% when the actual wear is 0.25% Sent from my SM-G900F using Tapatalk
  20. You don't have the other half of that spline part by any chance? I'd like to make one too. I quite like my DT 350 hubs and they use the same circular sawtooth ratchet mechanism. Sent from my SM-G900F using Tapatalk

  22. Yes when it is bright you may need an ND to slow the shutter but there are workarounds. Definitely try the small aperture first and in a pinch, a polarising filter works as a weak ND and you can adjust it to polarise or not as you wish. Sent from my SM-G900F using Tapatalk
  23. Actually, coveting your neighbour's camera while on a shoot is quite OK. And getting them to say 'sex' instead of 'cheese' works a lot better. Sent from my SM-G900F using Tapatalk
  24. If you must you can leave one of them on the rear. Get something more grippy up front. Lots of options 'cos almost anything is more grippy Sent from my SM-G900F using Tapatalk
  25. He he he.... it's a bike shop. They sell chains. Guaranteed they will say its worn even if not. But in this case it was probably way past 0.75. Don't re-use a chain pin. Once pushed out they are finished, especially on the narrow chains. Re-use in emergency only. Rather use a new pin or a powerlink. Powerlinks can be re-used but rather fit a new one with each new chain so they wear in with the chain. Some types need a tool to loosen them ( or some clever tricks).
