Specificatii tehnice:
The Chorus 2x12-speed groupset is fully compatible with the cassettes launched with the Super Record and Record 2x12-speed groupsets (11-29T and 11-32T) and it introduces a new cassette specification that will benefit the entire range of 12-speed mechanical drivetrains. The 11-34T 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).
