How do you find your crankarm length? I have a 2014 Felt B16 with a Vero FSA crankset 56/32T 110mm BCD. That's all the information I can find, so how do I know the crankarm length?

Usually labeled on the inside of the crank arm near the threading for the pedal.

Yes, on the crank arm itself, near the pedal. Probably a number like 165-175.

Now I see it. It was etched in so I had to use a flashlight to look. Thanks!

Just curious...I assume you made a typo on the inner 32T when paired with a 56. Is it a 42? You pretty much need the 42 for tighter gearing.

My guess is he switched the 2 and the 6.  He meant 52/36.
