Ok lets say the SRAM Omnium:

paired with a Pake frame (I know, sue me):

It says they both accept 68mm. Now, on the link to the crank with the included BB, it asks me to suggest a length, one being 165mm. Is this the length of the crank arms, or the bolt diameter? I'm looking for some decent frame suggestions, not looking to spend more than 800$ though. \
