    Do I have a Record or Chorus 10 Speed Campy Cassette?

    I've done a bit of research and am still not certain if I have uncovered a Campy Record or Chorus 10 speed 11-23 cassette.

    The details. A magnet is attracted to all cogs. All cogs appear to be the same color. The largets two cogs (21t and 23t) are connected via a titanium spacer (judging by the color) though it could be aluminum. Either way, the magnet will not stick to the spacer. The total weight without the lock ring and including all plastic spacers (and one metal spacer) is 205 grams. Approximately 5 years old.

    Based on the fact that a magnet will stick to all cogs, I'm thinking Chorus. Based on the weight, I'm thinking Record.

    Thoughts?

    The top picture is almost art. Some sort of prehistoric chainring shark.

    I'm pretty sure Chorus has all steel cogs with the larger ones on carriers. Record had either the carrier cogs in Ti or all but the 11T in Ti (the "regular" and "ti" versions of the cassette). Having had all three types in 10s that's been my experience (in various iterations of 11-21, 11-23, 11-25, and 12-25).

    Neither. That's Daytona or Centaur depending on vintage. Apart from the 2009-2010 model years and 14-23 combination which use all loose cogs those have only the largest two cogs on a carrier. Chorus/Record have the four (21/23 ending cogs) or six (others) big cogs in pairs on aluminum carriers (better than titanium for that application since the density is lower and strength high enough). Regular Record uses titanium for the four largest cogs instead of steel as on lower cassettes. Record Ti has all titanium cogs except for 11T starting cogs which remain steel. Chorus/Record also use all metal spacers while the other cogs have all plastic spacers except for the metal 2.5mm G spacer on the 11-23. Veloce and Mirage are all loose cogs. Veloce from 2009 on and Mirage have a galvanized finish which is shinier and more yellow than the unpolished nickel-chrome used on the more expensive cassettes.

    (If you were counting that was six levels of cassettes)

    I've never seen 10 speed polished nickel-chrome cogs like Campagnolo used through the 9 speed era (I didn't start accumulating 10 cog parts until this decade) and remain curious about whether the transition to unpolished happened with the cog count increase or came as a later cost-saving move.

    I think you are right, Drew. I found this. After looking at the bottom of the page, I think it would be hard to argue with you. Oh well. I'll see what I can get for it on eBay.
