The 12x Chorus cassettes for use with the disc or rim brake groupset.
The Chorus groupset is fully compatible with the cassettes from the Record and Super Record 2x12-speed groupsets (11-29 and 11-32) but also introduces a new cassette specification of 11-34.
The 11-34 cassette offers cyclists even more versatility and a greater choice and autonomy in terms of available gears.
Chorus 12-speed now therefore offers a total of three cassette options:
- 11-12-13-14-15-16-17-19-21-23-26-29
- 11-12-13-14-15-16-17-19-22-25-28-32
- 11-12-13-14-15-16-17-19-22-25-29-34
Technologies
- Same width as the 11-speed cassette: Totally compatible with wheels and frames.
- The two bigger sets of three in a single-block piece: It eliminates energy dispersion.
- Surface treatment: It increases durability and improves smoothness
- Same-thickness spacers: Ensures error-free fitting
