Identifying Campy cassettes

[cgolvin]

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

My understanding:

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.

Interesting observation. I've wondered about this.

Because no one putting out real power rode them...amiright? :banana:

There was one additional variant (sorry, had to be that guy)--for one year, Centaur 10 speed came as all loose sprockets--no carriers. I was sent one and complained, thinking the box had been switched, but in fact it was Centaur (w. the slightly different finish).

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.

Is it correct to say that Centaur, Chorus, and Record 10s cassettes all had nickel plated steel sprockets, and Veloce had galvanized steel?

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).

Good info about Campag 10-speed freehubs and cassettes.

11s..AND 12s:eek:
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

Good to know, thanks! I've been casually stockpiling 10S Chorus cassettes over the years, didn't know that the spacers vary. I think I may actually have a new one in a box somewhere, will take a look...then I will have to examine the installed cassettes to see where I deviated from the instructions. :)

If you mixed up the spacers, most likely your shifting will be off! :eek:

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