New Chorus DB 12-speed groupset: the Campagnolo product that combines racing performance with the needs of Endurance.
Designed for unforgettable outings where the entire day is spent in the saddle, the specific combinations of the Chorus 2x12 make it a versatile, simple and high performance groupset, however it's used: from Granfondo rides to adventurous Sunday spins to quick blasts on the bike after work.
The new Chorus DB groupset is launched on the market to expand the range of innovative technological solutions already provided by 12-speed groupsets. The new Chorus DB 12-speed groupset is available with the specific 48/32 and 11-34 combinations, suitable for those who spend hours and hours on the saddle on mixed terrain, while maintaining the racing performance guaranteed by every Campagnolo groupset. As per tradition, the use of different materials and consequent little additional weight, together with a rear derailleur redesigned to house larger cassettes are the main elements that make this new Chorus 12-speed different from the Super Record 12-speed and Record 12-speed groupsets

Description
CHORUS FRONT DERAILLEUR
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.
CHORUS ERGOPOWER DISC BRAKE CONTROLS
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 customizable, the new standard is embodied in the design of the Chorus levers. Apart from 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.
CHORUS REAR DERAILLEUR
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.
CHORUS CRANKSET 12X2 SPEED
The new Chorus crankset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fiber, it is produced directly molded 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 12 SPEED SPROCKETS
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) only compatible with our Chorus 12s drivetran. The new 11-34 cassette in fact offers cyclists even more versatility and greater choice and autonomy in terms of available gears.
CHORUS 12 SPEED CHAIN
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.
CALIPER CAMPAGNOLO
Campagnolo brake calipers: powerful, modulable and reliable..
The flat-mount Campagnolo brake calipers 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 caliper piston, cushions the vibrations during braking.
The different Campagnolo brake calipers were designed to be mounted together with the disc chosen by the rider and to always guarantee the highest level of performance. It is indeed possible to choose the brake caliper with a disc measuring either 140 mm (limited to cyclists weighing no more than 82 kg) or 160 mm in diameter. Careful attention was given to making maintenance and assembly operations easy: the pads have wear indicators and replacing them is facilitated by the absence of physical return springs. Additionally, work was done on the insertion of the disc in the caliper to make changing the wheel easier and faster.
CAMPAGNOLO ROTOR
Campagnolo is dedicated towards offering the best performance solution possible no matter what frame a road racing athlete chooses to ride or the tire he or she chooses to mount. As framebuilders begin to develop frame and fork designs that take advantage of the aerodynamic gains represented by direct mount brakes the Campy Tech Lab™ set forth to produce a pair of direct mount brakes that boast Campagnolo quality and performance standards. This completely new braking system from Campagnolo allows for a completely symmetric and efficient brake application thanks to its self-balancing design.
A high-performance disc-brake groupset must be twinned with rotors of equally high performance. When developing professional disc rotors and brake pads, the key is not only to deliver extreme performance but also to ensure safety, reliability and maximum heat resistance. The AFS-compatible Campagnolo rotors, with safely rounded outer edges, dissipate heat securely and evenly. In addition, they guarantee performance in hot environments that could compromise the functionality of competitors’ products.
Not only do Campagnolo disc-brake rotors maintain performance in extreme heat, they also provide the fastest deceleration with the least manual pressure compared to competitors – both in the dry and in wet conditions.
ULTRA-TORQUE™ CUPS
The Ultra-Torque system aluminium cups ensure maximum fluidity of movement and robustness for the bottom bracket axis. Available in eight different standards, to fit all frames on the market
