Description of Campagnolo Chorus Groupset 2x11 - Mechanical Rim Brakes

The Campagnolo Chorus drivetrain represents the perfect solution for the sophisticated cyclist searching for Super Record performance at a more competitive price. Fitting a Campagnolo drivetrain to their bike has always been the ambition of many keen cyclists.

The new Chorus groupset is the optimum choice for those wanting the best results that a mechanical groupset can offer, combined with appeal and Italian design at the best price possible.

The Campagnolo Chorus groupset consists of:

  • Chorus Ultra-Shift Ergopower 2x11
  • Chorus Skeleton Dual Pivot brake calipers
  • Chorus Ultra-Torque Carbon crankset 11-speed
  • Chorus front derailleur 2x11
  • Chorus HO rear derailleur 2x11
  • Chorus cassette 11-fach
  • Chorus chain 11-fach
Hubs and bottom bracket cups are not included. These can be ordered separately.


Campagnolo Chorus Ultra-Shift Ergopower dual levers

You can grasp the Chorus Ergopower controls any way you want: you'll always feel safe and responsive. The ergonomic design of the Ergopower body - now made of a lighter and stiffer material - enables you to grip the controls more firmly. The brake lever with double curvature and the classic double lever of the brake/shifter controls guarantee efficient braking in all conditions and easier operation.

Ultra Shift™ mechanism
with differentiated maximum number of upshifting clicks depending on the starting spocket


This groupset allows multiple shifting (up to 5 sprockets). Rapid positioning on the combination desired when there is a steep increase in the slope or when approaching a bend (up to 4 combinations with chain on the frst 4 sprockets, up to 3 combinations with chain above the fourth sprocket).

Campagnolo Chorus Skeleton Dual Pivot brake caliper

The compounds used yield superior braking performance and the lightened pad holders make pad replacement fast and easy. The dual pivot brakes ensure even more decisive and powerful braking.

Campagnolo Chorus Ultra-Torque Carbon crankset

X.P.S.S.™ (eXtreme Performance Shifting System) is the acronym that denotes one of the most effective and efficient systems ever, with one of the best shifting speed and precision even under load. The Chorus crankset with carbon fibre is the ideal partner for any competition.

UltraTorque™ technology
Pressure on the pedals transmitted efficiently without any power loss


Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.

Assembly is simplistic: one single oversize bolt is enough to integrate the two semi-axles. With regard to torque transmission efficiency, this system is equally as effective as a single piece axle.

Campagnolo Chorus front derailleur

This system is fast, responsive, and precise, and the chain shifts across chainrings with no hesitations. The Chorus 11-speed front derailleur is compatible with standard crank sets and the Compact. The geometry of the fork and the movement of the front plate have been designed and optimized to obtain maximum performance when used with the other Campagnolo components.

S2 System (Secure Shifting System) - optional selectable
The S2 version provides an integrated support for the seat tube. So additional support is possible for frames with a soft and flexible socket (e.g. full carbon socket). The derailleur can not turn away during the switching process.

Campagnolo Chorus HO rear derailleur

Chorus 11-speed's shifting precision is comparable to its higher tier siblings Record and Super Record. The design and geometry of the rear derailleur are exactly the same. The only difference lies in the materials used, which made it possible to keep a favorable price without lowering the performance levels. A groupset dedicated to competition like the Chorus™ 11-speed can't forego showing its true competitive spirit, and the carbon fibre front plate is the proof.

The HO version of the Chorus rear derailleur has been especially optimized for disc-brake frames with with 142 mm OLD. The derailleur mounting link and its design has been adapted to provide an easy mounting and dismounting of the thru axle or rear wheel. Furthermore the teeth of the upper pulley has been extended to guarantee precisely shifting also at high skew.

Campagnolo Chorus cassette

The form of the teeth is new and they have been treated to increase duration over time. The teeth have been designed to optimize the speed and fluidity of shifting. This form reduces stress on the chain which ascends more easily onto the higher diameter sprockets. The large sprockets are divided into sets of three and are mounted on an aluminium frame. Thanks to this, rigidity increases by 180% and the individual sprockets are 70% more resistant to torsion.

Campagnolo Chorus chain

Due to the used materials and the special anti-friction treatment, the 11-speed chain is quieter than ever and has a super smooth operation. The reduced width of 5.5mm with the new spacing and a special material has been envisaged for the outer links. It is necessary to use tool UT-CN300 to fit it.

The Ni-PTFE treatment ensures smoothness and long life. The Ultra-Link fastening system guarantees strength and operation with the 11-speed sprockets.
