i've noticed the pimp move on frames is to have the pivots use needle bearnings. word is, they are smoother and bear stress better. are there any companies out there using needle bearings in their hubs or cranks?
seems to me a needle bearings in either application could allow for a larger diameter hollow axle to save some weight.
thoughts?
