Thanks, I've changed cassettes several times before, only this time I had the problem. The lock nut wrench I use is Shimano-specific.
This might be one of those "Why didn't you say that in the first place?" moments (
), but when I got the new cassette, one of the spacers was broken, so I took one of the spacers off the old cassette to use on the new one (an identical Shimano cassette, I think).
I really need to get the wheel off and have a close look.
