I posted this on the Mech Forum, but I've always had good luck on this one. (Stupid Newbies, while they never learn?) Bought a wheelset that was said to be a Shimano 8/9 speed. When I got it, I tried to put my 8spd Hyperglide cassette on it with no luck. The freehub has uniform grooves all around. I'm assuming that this is a uniglide hub. Is it easier and cheaper to just buy a new Uniglide cassette, or can I replace the Uniglide freehub with a Hyperglide one?
