New 12x Chorus cassettes for use with the disc or rim brake groupset.

The new 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 new 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.
