servicing a rear hub...
I'm a moderate do-it-yourselfer. I do derailleur adjustments, drive-train removal/cleaning, lube etc...I've changed cranks a few times and even a bottom bracket or two. However I've never touched a hub, and I think I've got one that needs help.
Description: this is a cassette hub, not a freehub (ie, cartridge thingy that accepts 7-speed cassettes).
Symptoms. I noticed this tonight when I was making the change to the crappy winter wheels. As I was adjusting the derailleur, I noticed that if I held the pedals and the wheel was moving (ie coasting) the chain would sag. I pulled the wheel off the bike, and low-and behold the rotation of the cassette body was "lumpy" and stiff. Is this the result of having a crappy hub, cold weather (~30 F) or is it something that can be fixed.
If it can be fixed (without having to rebuild a wheel) is this something to be left to the bike shop guys or is labor enough that I would be well served by trying it myself?
