I have a 9-speed cassette that came with a Chorus-equipped bike. It's not titanium but how can I distinguish it from a Record unit? Happy to send you pics if you're interested.
The higher end cassettes have the larger cogs fixed in 2's or 3's to a carrier whereas for entry-level cassettes all cogs are loose and fit directly to the freewheel.
OK, here it is. It's a 12-21 and it has a titanium Campagnolo lockring. Condition is used but very good with little to zero tooth wear. Yours for £35 shipped.
