. . . my bike hubs this weekend. The rear one was making some weird noises so I learned how to pull them apart and regreased with some marine grade water resistant stuff (which is supposed to be good down to -40). Also had to replace the bearings as a couple of them were cracked. Then, as I was on a roll I replaced my chain (starting to stretch too far), took apart and cleaned the cassette, re-aligned the brake pads, and tightened up some loose spokes.
I'm excited for my next ride now!
