corey, the real reason to go chainless is for the experience :)
as mentioned it teaches you to be smooth and carry speed (e.g. ride seymour chainless, like 90% or more of cbc/pangor you don't need a chain) and i personally believe it can actually help you become a better rider…
plus it's even neat to be without all the drivetrain noise… when i ride w/out a chain i can actually only hear the damping on my shocks… which is kind of cool because normally i can't hear it at all.
yeah anyways
