Today I have decided that I have a downright hatred for surly hubs. Yes they are sealed hubs, but use a threaded on shoulder instead of an axle with a fixed shoulder, on a mtb disc hub instead of a axle for a mtb, they use a 9x1, the bearings in them are not 6000 series, they are 7091 series sealed bearings(small). I've been having an issue with the front bearings, though it was just the threaded on shoulder nuts just working loose, but take the axle out to find out one had 3mm of slop in the bearing on the one side and the inside race one the other side of the hub came out with the threaded on shoulder nut. Wheel was built back in december and did not suffer any hard front impacts. When it was quick release I had the same issue of the wheel feeling like it worked it's way loose on the 2nd ride. So I was pretty much sent a hub with defective bearings. One more issue, and I am seriously going to just get of the wheels and build up a new wheelset with anything but surly hubs.
