hi listers , i have seen bent axles on kids and adult cycles... i think in most cases cheapo imports and axles that are not sufficiently tempered or are made of inferior steel, a friend had a problem with a Raleigh back in the day and the answer from Raleigh... whose bracket axles were bombproof ,usually ,was that it hadn't been through the full hardening process, they had a batch like this which got missed and put into cycles, all sorted under warranty. lots of kids bike esp bmx type suffer when they add those stunt pegs which bend the axle, when they are added onto a cheapo bmx.. Colnago afficinados ,my younger brother has unearthed a neat colombus slx 57c/t C'nago in Edmonton, Alberta... which is where he lives these days... needs help with identifying said machine, model; etc perhaps one of you would mail me offlist , from what i can see in the shots he sent me it is on topic and has s/record gear., if he was closer i would buy it myself.. willie carton from coleraine n. ireland ...enjoying an indian summer september day 20deg..

I took apart many of my friends bikes and my own and my brother's. I never saw, or think I never saw a bent wheel axle nor a bent crank axle. After all, the difference in weight between a skinny teenager and a bulbous adult is only on order of 1 to 2 at worst. (130 lbs vs. 260 lbs give or take). The difference in power output is probably about the same for all participants in casual cycling too.
This last year I found a bent rear axle and a bent crank axle on another bike. Neither bike looked abused and neither bike was ridden by anyone outside of the above parameters I would imagine. How can we explain a bent axle then? I could understand it on a mountain bike that is ridden so that the rider regularly takes on ten foot drops but both these bikes were lightweights that are ridden on road, not on lunar landscapes or by Evel Keneivel types.
