I couldn't really see what it is without taking the wheel off. But it started to slip even after I had it in gear. Looking at it now though I can see how narrow the chain is with the teeth barely fitting into the inner plates. Maybe I should get a wider chain. Either that, or get a 10sp chain and use it with my 10sp wheels.

At this point I'll have to say I won't be riding it much. It is still February.
