well, since you all are so nice about dumb questions...

a) The bike at the gym says my rpms are mostly 70-75 rpm when I'm comfortable.(my real world bike doesn't have rpms) I"m supposed to go faster than that?????? Why? I have aways to build up to then...

b) How do you know if you have a "compact crankset"?


A url/ link is fine if this is too newbie...
