• CHORUS 11-Speed Rear Derailleur Campagnolo claims that the use of light alloy and composite reduces the weight while maintaining absolute operating precision. This is the fulcrum of the 11-speed systems. The 11-speed rear derailleur has a forged aluminum upper body which works on an enveloping and oversized carbon fiber or aluminum outer plate. The new form confers torsional rigidity which is 150% greater than the old design and contributes to the construction of a parallelogram with absolute operating precision. The cage pulleys are now made of a lighter material and reduce vibrations. Weight 192g.

• CHORUS 11-Speed Front Derailleur system is more rigid thanks to the use of the M-brace derailleur body while its life has been increased by the anti-friction treatment of the surfaces. Ultra-Shift front derailleur are more rigid while thanks to the special chain guide fork the operating speed and ease of use and adjustment are enhanced. Weight 76g.

• CHORUS 11-Speed ERGOPOWER™ ULTRA-SHIFT™ Controls Guarantee full braking power even with your hand in the high grip position. Its operation is precise and constant over time thanks to the use of polymer bushings and a new internal mechanism. Maintenance has been reduced to a minimum. The Ergopower Ultra-Shift controls are ideal for the 11-speed drivetrain. Weight 347g.

• CHORUS 11-Speed Cassette the additional speed led Campagnolo to devising a new support structure for the last six sprockets in two subsets. The form of the teeth is modified and they have been treated to increase duration over time. Weight 236g.

• CHORUS 11-Speed Crankset has been embellished by the SPECIAL SURFACE ANODIZATION treatment which renders the chainrings more resistant to wear and corrosion. Its asymmetrical toothing of the innermost chainring and the eight pins on the outside provide shifting immediate. Weight 680g.
