I'd like a nicer rear hub with more engagement for my 27.5 bike. I have a set of 29er Stan's Arches with 3.30 hubs sitting around. I was thinking about breaking down the rear wheel and relacing the hub to a new rim. Depending on the rim it might cost me $100 or so with spokes and such. Dunno if it's worth breaking down a good wheel or shop around for something built.
