I have an XT M730 rear hub with the original 6 speed UG freehub body. My plan is to swap it for a later 7s HG type body. But it's a hub only at the moment and I can't get enough leverage on the bolt to undo it without building it into a wheel. Before I do only to find that for some reason it's incompatible, can anyone confirm if the XT 6s UG body uses the "standard" freehub fitting?
