Here's a new one to me - my rear hub keeps loosening. I get the cones as tightened as possible without impeding rotation, crank down on the nut, put it on the bike, and everything's fine (a little side-to-side play, but nothing outrageous). Yet the next time I check it, there's way more wobbliness than I like. Today, after adjusting and tightening it last night, I did a tiny little skip and heard a noise, and lo and behold, it's wobbly again.
Hub is a Surly. I have another set of surlys that I don't think I've ever had to adjust. It's been in service for around a year, and I've only noticed the looseness in the past month or two. The wheel joined me on a January trip across the hood of a car, but seemed fine thereafter (wasn't even out of true). Any thoughts, junior detectives?
