Just ordered a frame with a 142mm rear end. I already have a couple 135x12 hubs, and a lathe. Since I'm cheap, I'd rather just make 2 3.5mm spacers to fill out the gaps on each end than buy new axles. Yes, I know installing the wheel will be annoying.
Question is, what is the OD of the shoulder on a 142mm hub?
