Dura-Ace 7 speed Uniglide cassette (CS-7400-7), 13-14-15-17-19-21-23.
From the late 80s. Almost unused --- I bought it when I had some 105 UG hubs, not realising that the locking sprocket has a different thread to the rest of the UG cassettes (to allow a 12T sprocket). The 14-23 sprockets have been used once for a downhill MTB race by my son in an effort to look "pro", before he realised that it was terminally uncool to use his dad's vintage kit! So yes, these sprockets work on hyperglide freewheel bodies just fine. If I'd had more sense, I could have used the magic BNIB, but at least I still have the box.
£25 posted.
