I need a Freehub that can be used with a 1990 shimano XT hub. A standard Hyperglide would do it but I don't know if the XT version had a better quality unit than standard Deore/Exage kit.
Ah, Uniglide deffo, check the even slotts around the edge, Hyperglide will have a single wider groove. Uniglide cassettes fit Hyperglide freehubs but not the other way around sadly.
Many thanks for the pic but sadly yours won't work.
