Identifying Campy cassettes
I was certain that this topic had been covered but, if so, I've been unable to unearth the thread.
I know that in general one can distinguish between upper and lower level cassettes by the number of individual cogs versus those on a carrier, but is there a method for differentiating among the upper levels? Let's initially restrict ourselves to 11 speed. Is it even possible to determine whether this 11-25 I'm holding is Chorus, Record, or SR, and, if so, how? My question also applies to 10 speed but for now I'll be satisfied with an answer on 11. Thanks |

Chorus - all steel, with lots of drilling and two carriers Record - biggest cogs are titanium, rest are steel Super Record - all cogs are titanium I'm more confused about 10-speed and identifying Chorus vs. Record vs. Centaur/Veloce.

I can't say for 11s. But I've ridden Veloce through Record in 10s (and yes, Record with the ti cogs was a waste of money).
Centaur and up have a more grey finish on the steel cogs. Centaur has one set of cogs, the biggest 2 or 3, pinned. Chorus has multiple sets pinned, I think as many as 3 sets of cogs (and I think up to 6 cogs total). Record would have the same number of cogs pinned as Chorus, but the ti cogs are brighter silver than the steel ones. If you somehow got the top half of a Record cassette vs the top half of a Chorus ... I have no idea how to differentiate. I have a feeling that the steel parts were exactly the same between the top 2 groups. Less sure if the steel bits on the Centaur cassettes shared the same manufacturing and finishing process as Chorus/Record, but they did look pretty similar. Veloce is completely loose and the finish looked more rough. But for my money, it shifted and wore about as well as the higher level stuff, and I was completely comfortable riding Veloce cogs on the otherwise all Record and Chorus drivetrain. Furthermore, Veloce cassettes didn't notch the freehub body despite being all loose. |

11 speed:
Super Record: Largest 6 sprockets titanium; largest 6 sprockets riveted to spiders Record: Largest 3 sprockets titanium; largest 6 sprockets riveted to spiders Chorus: All sprockets nickel plates steel; largest 6 sprockets riveted to spiders All others: All sprockets steel; largest 3 sprockets riveted to spiders 10spd Record Ti: All sprockets titanium (except 11 tooth); largest 4 or 6 sprockets riveted to spiders Record: Largest 4 sprocket titanium; largest 4 or 6 sprockets riveted to spiders Chorus: All sprocket nickel plated steel; largest 4 or 6 sprockets riveted to spiders Centaur: All sprockets steel; largest 2 sprockets riveted to spiders Veloce: All sprockets steel; all sprockets separate Notes: Nickel plated steel sprockets are a white-ish silver, galvanized steel sprockets are a greyish silver, titanium sprockets are a yellowish silver. Steel sprockets are strongly attracted to magnets, titanium sprockets are not attracted to magnets. For Record/Chorus 10spd cassettes, 12-23 and smaller cassettes have 4 sprockets on spiders, larger cassettes have 6 sprockets on spiders. Last edited by Mark McM; 07-18-2018 at 02:58 PM. |

Interesting observation. I've wondered about this.

If you get a 10's cassette, make sure you keep the little pamphlet that comes with it...showing where the spacers go. 3 different widths on the loose cog ones....Veloce and Loose cog Centaur (1.6 MM, 2.55 MM, 2.4MM). And he ones with carriers....the spacer before a carrier is different from any of the loose cog cassettes.
On the Centaur with top 2 cogs pinned together....3.05 MM spacer before the cog. And the recent 10's 12-27 and 12-30 "Centaur" cassettes had the top three cogs pinned together on a carrier. Also....they had same 2.5 MM space thru out. I keep the pamphlets/directions for use for all these. Have one for Chorus/Record also. Last edited by Ralph; 07-18-2018 at 06:30 PM. |

Then, I think that for 11s cassettes, H11 (i.e. Centaur and Potenza) and Chorus-SR all have nickel plated steel (insofar as they have steel cogs). |

Chorus, all steel. Record, last 3 are ti. SR, last 6 are ti 10s Chorus/Centaur/Athena/Veloce-all steel Record-last 4 titanium There was an all ti Record 10s cogset..for info

Easiest way to tell the difference? Use them. First to wear out is the Super Record.
