Motivated

Subtle, but definitely an April Fools joke. The spring pushes on the outer race ... this won't compensate any play. A spring pushing on the axle would not compensate play anyway because the forces from riding are way too high - and if the spring force was high enough, it would cause wear in the radial bearing which is not designed for that.

Adhesive failure means the load bearing capability is very low - it's a binary situation - either very strong or very weak. Basically there is just friction holding the tube in place - this could have failed just riding trails. I have designs (and most importantly the process control developed and defined) in space applications and commercial planes that rely on surface preparation of aluminum for adhesion. We normally use plasma etching, a primer and a curing oven before bonding). The loads and the lifetime requirements are pretty challenging. I guess that on a MTB those challenges are even more difficult ... plus the consequences.

@vinay: I don't think anyone is riding it with no hands. After a second look ... I think it's a medical device for training mobility of the lumbar, not a serious bike.

I bought my 29" x 35mm wide Derby Rims in November 2013. I ride them as hard as I can. They have many scratches, some are more than surface deep, but they look pretty fine. I did rebuild them due to moving to a new bike with new hub standards. They've outlived every other component on my bike. I don't see any reason why they won't last another 10 years.

@Arierep: interesting point regarding balance. A combination of riding mostly narrow hiking trails, riding more technical trails, riding with better riders, and getting older (+50) ... I find that micro balance and precision to hit and stay on the right line is getting harder. I always wear a backpack and have no issue with the comfort, but the high CG might be a the best reason to try a fanny pack instead.

I think it's because the downtube is relatively straight and not a hockey stick.

@motdrawde: according to wattbike - *the* highest watts are produced by BMX and DH pros - even higher than track cyclers because they use very tall gearing (for high speed) that isn't quite optimal for peak watts at the start. We are talking about 2200 watts for ~3 seconds.

I invented this. You can see my previous comments on a moving idler. Enjoy a bottle of Raki in gratitude :-) My next invention is to solve pedal feedback with a freehub clutch, perhaps like a Classified hub, that is only engaged when the cranks are rotating. So, bluetooth crank rotation would send a signal and the freehub would engage. Of course only solves pedal feedback when coasting.

It's a better indicator than the company going bankrupt because no other company sees the upside in the future.

PB ... how do you know it rides like a Session ... when was you last Session bike review?
