I'm overhauling a 1989 Miyata 1400 and was surprised to find what I think is a cassette-style rear hub rather than a thread-on freewheel--none of my freewheel tools are even a close fit. Can someone help me figure out what tool I need to remove this?
I have a 13-21 thread-on freewheel that I was looking forward to installing but I guess that's not going to work here: are these cassettes readily available in different sizes?
