Campagnolo Chorus 11 Speed Groupset

The Campagnolo Chorus drivetrain represents the perfect solution for the sophisticated cyclist searching for Super Record performance at a more competitive price.

The 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.

Crankset:

This completely redesigned crankset represents increased rigidity as well as fresh and cutting edge aesthetics.

• Ultra-Torque? axle
• New chainrings
• Differentiated number of pins depending on the chainring combination
• Hollow crank and spider arms with Ultra-Hollow? Technology
• Double standardized bolt circle diameter on all combinations
• X.P.S.S.? Extreme Performance Shifting System
• Bottom bracket included

Shifters:

From any position on the handlebars, the ergonomics of Ergopower? controls enable you to grip the controls more firmly.

• New Vari-Cushion? brake lever hoods with variable density and surface finishes
• Ultra-Shift? ergonomics
• Ultra-Shift? mechanism with differentiated maximum number of upshifting clicks depending on the starting sprocket
• Brake lever hoods and cable housing are available as spare parts in red and white

Rear Derailleur

The Chorus rear derailleur has changed dramatically and offers significant performance enhancements thanks to its revolutionary new design. Campagnolo engineers sought to create a more efficient and better performing rear derailleur and in doing so completely redesigned this component both inside and out.

• Rear derailleur fixing bolts in aluminium
• Ultra-Shift? exclusive geometry parallelogram
• Embrace Technology?
• Front plate and cage in carbon fibre

Front Derailleur

This system is fast, responsive, and precise, and the chain shifts across chainrings without hesitation.

• Special inner cage design
• New cage in light moulded alloy
• S2 System (Secure Shifting System)
• CSD (Chain Security Device)
• Derailleur cable deviator insert
• Derailleur clip clamp
• Front derailleur mounting tool

Brake Set

For a fast descent you need a safe and reliable braking system that is powerful and adjustable. The Chorus system offers a shorter braking distance and complete control of braking power.

• Exclusive brake pad coupling/uncoupling system
• Special compound
• Skeleton brake arms
• Front/rear differentiated braking
• Lighter pad holders
• Dual pivot front/rear version

Cassette

The additional speed led us to devising a new support structure for the last six sprockets in two subsets. The form of the teeth is new and they have been treated to increase duration over time.

• Ultra-Shift? teeth design
• Reinforced mounts for second and third triplets
• Ultra-Shift? synchronisation
• Nickel-Chrome surface treatment

Chain

The new 5.5mm thickness has been combined with new materials and a special anti-friction treatment, which permits outstanding fluidity.

• Ultra-Link? chain link connecting system
• Ultra-Link? chain links
• Special steel links
• Antifriction NI-PTFE? treatment
