Huh ? The longest cranks I have on any of my bikes are 170mm, and all my fixed gear type bikes have 165mm. However, I can hardly tell the difference unless I'm spinning really fast or racing. Far more important is getting your seat position dialed in and having a smooth efficient pedal stroke. As to pedal strike, BB height is just as significant a factor as crankarm length, and some SS bikes are based on road frames, which have low BB's.
