Just curious, is your seat-post 0mm setback or something more like 20mm?

ergo, buy short cranks.
Dropping 1cm from 175mm to 165mm really doesn't make a difference for hitting IMO, as long as you're not riding a road conversion frame. Track/Fixed spec'd frames have a much higher BB shell (so does cyclocross) for this very reason. Many people ride the shorter cranks to be able to spin much higher. If you're on an old Schwinn Road conversion, or any conversion really, the length of the cranks would play a bigger role.
