Hard to find, last generation eight speed version of Shimano’s proprietary UniGlide freehub cassette. UniGlide was fairly short lived and used a locking small sprocket to hold the rest of the sprockets on like the Suntour cassette system, the later freehub bodies were compatible with HyperGlide too. This eight speed cassette will not work with the Dura-Ace rear hub but will work with all other 8 speed UniGlide compatible rear hubs, it is ideal for the 600 (FH-6402) and 105 (FH-1056) hubs.
