#!markdown @JoeDick - i don't think it is the diameter that is different, 'cos i just used my standard middle ring bolts for the NSB 30t ring. In fact i may well be using singlespeed bolts not even double ring bolts… @Heckler - Pretty sure that X Sync has a much more refined tooth profile, which 'may' improve retention. Giving how well my cheapy setup is working, i'm not likely to be rushing to X Sync any time soon. And given that King won't be making a XD driver soon i won't be on XX1 either.
