• Has anyone got one of these old Shimano cassettes knocking around? After my rear hub broke, a friend gave me a rear wheel to tide me over while I get a new wheel built up. It has a Shimano 600 FH-6401 hub which I believe takes 7 speed and is uniglide/hyperglide (not familiar with Shimano parts). I don't want to spend very much as it's just a temporary measure, and not too worried about condition. I'm in SE London (Brockley).
