Campagnolo Chorus Disc 12-Speed Groupset

Description

Campagnolo Chorus Disc 12 speed Groupset features powerful hydraulic braking, carbon materials and smooth lightweight shifting making this performance groupset one of the best in its class and a competitor to Shimano’s Ultegra groupset options.

Please note, Campagnolo rotors are not supplied with the groupset.

Campagnolo Chorus 12 Rear Derailleur
The rear derailleur is a totally new design. The top jockey wheels sits in front of the cassette and very close too it ensuring maximum chain wrap around the sprocket engaged thus minimising wear and maximising shift speed and accuracy. The cassette range is wider. The shifters are not called Ergos for nothing and the thumb shifter has been positioned so downshifting from the drops is even easier than before (it was never hard).

Chorus Front Derailleur
The new Chorus derailleur incorporates the same design that separates the upper from the lower semi-rod, eliminating the free stroke for more immediate, responsive upshifting. Design of the 2×12 speed front derailleur and its trajectory angle mean wide tires measuring up to 32 mm can be used, while the new design of the cage and dedicated positions for each gear position ensure extremely precise and fluid derailleur performance.

Redesigned Chorus Chainset
The Chorus crankset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fibre, it is produced directly moulded without any surface coating and has an Ultra-Torque steel axle like the Record crankset. It is versatile thanks to its new ring of 123 mm bolts that, while giving it an extreme-performance structure, also ensures a wider variety of use segments.
Available with 165, 170, 172.5 and 175 mm cranks, the new smaller ring of bolts on the Chorus crankset makes it compatible with 52/36, 50/34 chainrings and with the brand new 48/32 crowns.

Chorus Brake Callipers
The flat-mount Campagnolo brake callipers ensure powerful, modular braking in any situation owing to pistons measuring 22 millimetres in diameter. The pad return is now optimised to ensure that there is no friction when the brake lever is released. A special metal plate positioned between the pad and the calliper piston, cushions the vibrations during braking.

Chorus 12-speed Cassette
The 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) only compatible with our Chorus 12s drivetrain. The new 11-34 cassette in fact offers cyclists even more versatility and greater choice and autonomy in terms of available gears.
