Product ID: 1131635

Despite having one more sprocket than Campagnolo’s 11-speed cassette, the Chorus 12-Speed Cassette is still compatible with the same wheels and frames without any need to re-dish or change the freehub body.

The range of options should be sufficient to cope with any hill or route, and the top three sprockets can be interchanged with those from another 12-speed cassette so that the ratios can be tailored to the ride.

Please Note: The new Chorus 12-speed 11-34 cassette is not compatible with Record or Super Record 12-speed groupsets.

Campagnolo Chorus 12-Speed Cassette

The Campagnolo Chorus 12-Speed Cassette is the same width as the 11-speed cassette, so it remains compatible with the same wheels, freehubs and frames. The smaller spaces mean quicker shifting, and the surface treatment improves durability and shifting smoothness. The biggest six sprockets are manufactured in two blocks of three for better stiffness and power transfer; this also means that the largest block can be swapped with that from another cassette to customise the cassette for a particular route.


  • The two bigger sets of three in a single-block piece to eliminate energy dispersion
  • Surface treatment: It increases durability and improves smoothness
  • Same-thickness spacers: Ensures error-free fitting
  • Compatibility: Same width as the 11-speed, no need to change or update wheels
  • Smaller spaces: Faster, more precise shifting
  • Sets of three in single-block steel: Stiffness and elimination of power dispersion
  • 25-29-34 set of three available as a spare part
  • Can be converted from the 11-32 cassette
  • Claimed weight: 306 grams (11-29 version)
