Crank arm length recommendations....Cima Coppi
Aug 28, 2001 10:05 AM
Hello again everyone,

I'm in the final stages of planning my CX purchase and have come across yet another measurement that is stumping me. What crankarm length should I use. On my road bikes, I use 180mm crank arms, as I have an 87cm inseam. Should I go with this length on the CX bike, or should I be concerned about clearance and spinning and drop back to a shorter length.

As always, your opinions and recommendations are greatly appreciated.

no reason to change, you BB will be higher off the ground than your roadie anyway so cleareance is not much of a problem. Use what you are used to.
