roadbikes do not come close to the torque created on a mtb...yet you still sometimes see steel on good mtn bikes. Given aluminum has almost taken over mountain biking...but my point is, if you have torque transfer issues on a roadbike, then that bike was either:
a) designed to be light, in disregard to performance
b) poorly designed
c) meant for a significantly lighter rider (much like me being 220, riding on an ultralight made for a 140-150lb twiglet).
either way, it's a case of the wrong tool for the job.
