Do any of you guys know what kind of hubs these are? I think they are hyperglides but I don't know, I don't really know the difference. They're on a new set of Alex A-Class R 2.0. I wanted to get a Shimano 10 speed cassette to put on them. But I don't know which to purchase, maybe they're all the same. Which will fit?
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
All Shimano 10-speed cassettes will fit on any 8/9/10-speed Shimano compatible freehub. There is a 1 mm thick spacer that goes behind a 10-speed cassette if used on anything but a specific 10-speed freehub. It comes with the cassette so don't overlook it.
