The new Chorus groupset is fully compatible with the cassettes launched with the Super Record and Record 2x12-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.
The two bigger sets of three in a single-block piece, eliminating energy dispersion.
New surface treatment increases durability and improves smoothness.
Same thickness spacers ensure error-free fitting.
25-29-34 set of three available as a spare part, allowing users to upgrade from the 11-32 to 11-34 cassette.
