Use one of the on line calculators (Greenspeed), you will probably need 175mm.

172.5 but remember, put 3 people in a room and ask about crankarm length, get 4 opinions. Do ya like the FSA length? Get the same. I agree with FSA tho, not impressed with their offerings.

I concur with Peter's 172.5 for most people at 5'11". If you have extraordinarily long legs you might think about getting 175s, but I wouldn't without an extremely compelling reason.
