It can/will fit a 130mm rear OLN, either with a bit of brute force and ignorance, or there is a guide somewhere where you can swap one of the washers out to reduce the width needed to 130 proper.
In an ideal world, the rear cable stop needs to be reversed (if you're looking at building up a frame) as a 'regular' gear setup goes shifter(bare cable)>cablestop>covered cable loop into the rear mech, though the Alfline takes bare cable (so if you have your shifter cable covered, it'll need a stop to 'uncover' it)
