Description
From the first generation of freehubs produced this Shimano 600 EX UniGlide cassette is a 6 speed, close ratio version with 13 to 18 teeth. Shimano introduced the freehub / cassette system in the late 70s and UniGlide utilised a threaded top sprocket (like the later Suntour cassettes) and is not compatible with HG freehub bodies. This is the wider thread top sprocket so is also not compatible with the Dura-Ace freehubs, your freehub must be a 6 speed version too – complicated I know!
