I got a new cassette, with an 11t instead of a 12t little sprocket, and it seems to be noisier when spun fast (haven't ridden on it yet). Is this normal? I got a new chain several months ago but was running it with my old cog, which apparently is a bad idea.

Or does it just need to wear in a bit?

Have you still got the same free wheeling hub? Cassette itself will not really make noise but click is from hub.

The cassette came with a spacer, but I already had one on my wheel, and the sprocket seemed to fit perfectly... I wonder if that had to do with it. Probably not.
