I'm pretty new to bike mechanics and am hoping someone can point me to someplace that I can learn more about bottom brackets and cranks. I just picked up a new bike with Shimano EX400 Exage 170mm crankarms and (I believe) 144mm chainring, both of which I would like to change. Trying to figure out what my options are and such.
Thanks in advance,
Dan
