The new Chorus groupset is fully compatible with the cassettes launched with the Super Record and Record 2×12-speed groupsets (11-29 and 11-32) and it introduces a new cassette specification (11-34) that will benefit the entire range of 12-speed mechanical drivetrains from now on. The new 11-34 cassette in fact offers cyclists even more versatility and greater choice and autonomy in terms of available gears. Mechanical groupsets with 12-speed transmission now therefore offer a total of three cassette options (11-29, 11-32, 11-34).

• Same width as the 11-speed cassette
• Totally compatible with wheels and frames
• Smaller spaces – Faster, more precise shifting
• Same spacers – easy error-free fitting
