You guys...what am I looking at to possibly upgrade the bottom bracket and crankset on this thing (ok, shoot me)? I mean in terms of specs...not price. I know nothing about these bottom brackets, etc. for this bike. I know the first question you will ask is "but WHY on earth would you change it out?" I know, if it works, don't change it. If it ain't broke, don't fix it.

I agree, but....just wondering. I hear you....whoever that was who just told me to put down the wrench and step away slowly. Might even tinker with the brake set - got a guy locally who has a set of new-ish 105 6700 brakes. Could be a fun experiment. Purists calm down, not letting go of any original components. Just feeling evil.
