also, the dura ace road cranks are hollow. they are no good for fixed gear, especially if u plan to ride on the street. they WILL snap or crack at some point. It's also very difficult to get a straight chainline with the octalink bb type crank arms. the bb's dont come in many sizes, there is a fixed version of the dura ace bb but its about £60 i think. basically dont get thre road cranks!
