  1. Crank itself is compatible with BB30 or PF30 frames, but the bottom bracket that's included is only for BB30 frames. This crank will NOT work in anything other than a PF30 or BB30 frame. We get a lot of people who buy BB30/PF30 cranks who can't use them. Please identify your frame's BB shell prior to purchasing this crank.
  2. N10 is the same as N11. This crank was made prior to FSA releasing 11 speed cranks. Their new cranks are labeled N10/11, which basically means that the chainrings and cranks for either are identical.
