What brand cassette is it Maxvision? Mebbe it's a bad 'un?
Ya know what...alignment just might be the cause. I changed my rear innertube from a flat the other day, forgot to tighten the axel nuts, went for a short ride and...well, you can figure out the rest. Wheel didn't come off but it sure came out of alignment... Was just about the same angle and the teeth on my gears are now.
Thanks for the post BarelyAWake
