Campagnolo Chorus 12 speed has arrived. This is way more than just adding one sprocket. Everything has changed.
Please note unless you specifiy other wise in notes the BB supplied with british threading. See listing text for options. The price will not be altered for a different BB type.
The new Chorus rear derailleur benefits from the same technology and design of top-end Campagnolo products, incorporating the sophistication and performances of the 12-speed Super Record and Record. With just a few changes in the materials used for its construction, like the external plate and derailleur cage in aluminum, the Chorus version produces exactly the same performance as the two more expensive groupsets with the addition of just a few extra grams. Chorus brings with it the same technology as the next level up, like the new optimized trajectory on bigger cassettes and fantastic 3D EMBRACE technology. The latest evolution in Embrace technology not only keeps the rear derailleur vertically aligned in the perfect position for each sprocket, it now makes the upper pulley wheel advance perfectly in the direction the bike is advancing. 3D EMBRACE technology and 12-teeth pulley wheels makes this rear derailleur suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected.
The fantastic ergonomics that over the years have become a sort of calling card for Campagnolo have been even further improved with the latest introduction of Super Record and Record 12-speed transmissions. Not just ergonomic but also customisable, the new standard is embodied in the design of the Chorus levers. The brake lever, constructed in aluminum but with a coating that enhances its finish and its feel, Chorus Ergopower are almost identical to those on the Super Record and Record controls. Ergonomic characteristics, such as the new design of the brake lever hoods, the design of the brake lever and bigger gear levers, team with characteristics that make the shape of Ergopower controls unique for cyclists’ needs. The various positions possible for Ergopower controls mean they adapt better to different hand sizes. Campagnolo’s tried and tested one-lever-one-action philosophy ensures no-confusion control, regardless of the cycling conditions or the cyclist’s position. The internal Ultra-Shift mechanism controls the 12-speed rear derailleur, letting the rider shift up by up to 3 sprockets and down by up to 5 sprockets in a single movement. Chorus controls deliver the same extremely durable, soft shifting performance of the other 12-speed groupsets thanks to the same new cables and their housings.
The precise, extremely fluid movement of the front derailleur is achieved in part thanks to the new cables and their housing and in part because of the design and construction of the 2x12-speed 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 2x12 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.
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).
|Combinations||11-29 •11-32 •11-34|
|Weight||306 grams (11-29 version)|
Versatility and extreme results in terms of transmission are here teamed with brakes that offer powerful yet modular braking performance, ensuring excellent levels of control. Chorus levers guarantees safe, powerful, modular braking performance.

In order to guarantee impeccable, reliable performance even with bigger cassettes, precision shifting by front and rear derailleurs has seen design of a 12-speed chain entailing huge research and development efforts to make it as reliable and long-lasting as an 11-speed chain, despite being narrower than the latter. The new 12-speed Chorus groupset benefits from a new Chorus 12 chain that ensures the same reliability and the same performance levels as that of the Super Record category, its 110 links weighing only 241 grams.
The new Chorus crankset comes with new options. Technically advanced thanks to unidirectional construction technology in carbon fibere it is produced directly molded without any surface coating and has an Ultra-Torque steel axle like the Record crankset. 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 rings.
|Length||165, 170, 172,5, 175 mm|
|Combinations||32/48, 34/50, 36/52|
|Weight||718 grams (172.5 version with 34/50)|
