[Crunchy]

I recently had to change my chain as a couple of rings had worn or snapped. It was then that I noticed the rear sprocket had side play, so I took it off. The rear spacer/clip had come loose and the sprocket had worn the hub down so much that it was almost imposible to adjust rear wheel.
It looks like I'm going to have to change the swing arm. You had better check yours ASAP
