Pro and durable.

The Campagnolo Chorus 11 Cassette is built on the same Ultra Shift platform, with every bit of applicable technology, as the Record 11 and Super Record 11 cassettes you see in the pro peloton. The legendary cog tooth synchronization, shaping, and spacing — they're all here. The only difference is that Record and Super Record incorporate either three (Record) or six (Super Record) titanium cogs in their cassettes. This means they save 29 and 53 grams over Chorus, respectively. But titanium is also softer than the nickle-chrome coated steel used in the entire Chorus cassette, so the cogs will wear more quickly.

If you've been reading up on the 2015 models of Campagnolo's top-end components, then you know that there are compatibility issues between them and previous iterations. The cassette is the one exception to this rule on the drivetrain. All Campagnolo 11-speed cassettes work perfectly with all Campagnolo 11-speed shifters and derailleurs.

The Campagnolo Chorus 11 Cassette comes with a lightweight alloy lockring.

  • Steel cogs on an alloy carrier
  • Alloy lockring included
  • Chorus cassettes compatible with all iterations of Campagnolo 11-speed drivetrains, even the most recent

Two bikes: Custom carbon Super Record complete with 11-25 SR cassette; Titanium cross bike with Record parts and Chorus 12-29 cassette. The knees have reached an age where a 12-29 makes more sense, so here is some data on Campy 12-29
11-speed Cassettes:
Super Record (reported wt) 220 grams, $491. Record (reported wt) 256 grams, $332.
Chorus (actual wt, new) 291 grams, $150.

As best I can tell, the cassettes I own function similarly (very well). After a few miles, they are both covered with chain oil and look the same. For the significant price difference, I decided I could tolerate an additional 1.5-2.5 oz so I went with Chorus. It is beautifully machined and worthy of my carbon bike.


All in my head...

  • Familiarity:I've put it through the wringer

I`m a Campagnolo junky, I love the stuff, I have 2 bikes with Super Record and 1 with Chorus, about a week ago I did the math on the weight difference between the 2 that are the new 2015 version and without the cassette it came out to be like 150 grams and they really are the same as far as looks and more importantly operate equally. The cassette (11/27) is I think 75 grams heavier but after a year of hard use looks like new after its cleaned up, the super record TI cogs do not after half the miles, am I going to replace the super record cassette with another when it`s time...? probably, is that smart or will the bike perform better...? no and probably not, factor in the money.. knuckle head comes to mind...

I changed my 11-25 for this 11-23, now I have a 18 tooth gear which is right on my sweetspot. 19, 18, 17 are my favorite gears. With the 11-25, I had a 10 rpm gap between 17 and 19.

Unanswered Question

Does anyone provide the intermediate tooth numbers of the various combinations for the cassettes?

Is it possible to use this on a 10-speed campy hub? I am looking to be able to go back and forth between current setup. Do i need to take one cog off? Or can I use it as is. I have an 11-24 on their now and moved to an area where there is a lot more hills/climbing.

Best Answer

This will not work on a 10 speed set up, you would have to have an 11 speed derailleur, freehub body, and shifter.

Campagnolo 11 speed cassettes are compatible with 10 (and 9) speed freehub bodies. Per the manufacturer:

However,you would definitely need an 11 speed shifter to make use of all the cogs, and possibly an 11 speed derailleur as well. Some report that a 10 speed Campy rear derailleur will shift properly if paired with an 11 speed shifter, but I can't personally confirm.

Removing 1 cog to "turn this into a 10 speed cassette" is not an option


Its heavier but at the right price

  • Familiarity:I've used it several times

I have 3 bikes on Campy and 2 on Shimano.

The two on Campy are Record and the one on Chorus. I have to say, this is a heavy cassette (naturally) but if you can handle a little heavier, the cassette is flawless and works just as well as record.
