Recently got a NOS set of wheels with Campag Record/Chorus hubs and an 8 speed cassette, but it is unlike any cassette I have seen from campag. It's a 21-11t 8 speed cassette and the 11t cog is also the lockring. Is this a 7speed hub and cassette with a Campagnolo converter kit to make it eight speed, or was this a standard 8 speed option as I can find no record of it. The cog/lockring is a genuine Campag part rather than some after market thing (like the TNT cog/lockring). Can anyone help identify what this is?
Cheers,
Pete
