    external are both 68 and 73 and usually the axle length is the same, unless its for boost or fatbike or something, probably better to ask in gt section, or drivetrain section for more accurate info.

    I could be incorrect but I believe on current bikes, itís dependent on the bb and crankset you use. I would look at the crank and bb manufacturer.
