    as far as i know 168mm Q factor is what you need for a modern full susser. 156 is for old school bikes with skinny frames. I hope i’m right as i’ve just ordered some XX1 cranks in 168mm.

    You need to measure the width of your chain stays to make sure the ccrank arms miss them. 168or156 =inside crank arm to inside crank arm i think
