Individual Product Descriptions:

Chorus Ultra-Shift, Ergopower, 11s controls:

You can grasp the Chorus™ Ergopower™ controls any way you want: you’ll always feel safe and responsive.

The Ergopower Ultra-Shift controls are ideal for the 11-speed drivetrain. The ergonomic design of the Ergopower™ body -now made of a lighter and stiffer material - enables you to grip the controls more firmly. It could not be otherwise given the reduction of the working spaces. The right-hand allows you to shift the chain up to three speeds upwards and up to five downwards. The advantage is in the excellent shifting speed in every situation. Operating fluidity has also been improved. Thanks to a favourable lever ratio the force required for actuating the front and rear derailleurs is a lot lower than with the old controls.

Features:

• Large support area
• Mechanisms on bearings
• Carbon brake lever
• Greater support area
• No-Bulge cable passages
• Weight: 337g

Chorus 11s front derailleur:

This system is fast, responsive, and precise, and the chain shifts across chainrings with no hesitations.

Ultra-Shift front derailleurs are more rigid while thanks to the special chain guide fork the operating speed and ease of use and adjustment are enhanced. Furthermore, the anti-friction treatment extends their lifetime. The fastening system has also been redesignedin the clamp versions for improved compatibility with the bicycle frame.

Features:

• Braze-on fitmint
• for double standard and Compact crankset
• Weight: 76g

Chorus 11s rear derailleur:

Chorus™ 11-speed’s shifting precision is comparable to its older siblings Record™ and Super Record™

This is the fulcrum of the 11-speed systems. The 11-speed rear derailleur has a forged aluminium upper body which works on an enveloping and oversized carbon fibre or aluminium outer plate. The new form confers torsional rigidity which is 150% greater than the old design and contributes to theconstruction of a parallelogram with absolute operating precision.
The cage pulleys are now made of a lighter material and reduce vibrations.

Features:

• Redesigned parallelogram
• Forged aluminium body
• Carbon fibre front plate
• Pulleys made of anti-vibration material
• Weight: 186 g

Chorus 11s cassette:

Every sprocket tooth has been designed to achieve the maximum synchronization, shifting speed, and silent operation.

The teeth have been designed to optimise the speed and fluidity of shifting. This form reduces stress on the chain which ascends more easily onto the higher diameter sprockets. The large pinions are divided into sets of three and are mounted on a new aluminium frame. Thanks to this, rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.

Features:

• Special tooth profile for the 11-speed system
• Nickel-chrome treatment
• Light alloy lockring
• Weight: 230g

Options:

11-23, 11-25, 12-25, 12-27, 12-29.

Chorus 11s chain:

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

The reduced width of the chain to 5.5 millimetres, new spacing and a new material has been envisaged for the outer links. The pins are hollow inside to reduce the weight while maintaining strength. 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.

Features:

• 5.5 mm wide
• Ni-PTFE treatment - this is a special treatment that prolongs the life of the chain
• Ultra-Link System - special fastening system developed for the 11s chains with an extremely high retention force of the pins
• Weight: 295 g

Chorus Ultra-Torque Carbon 11s crankset: Standard or Compact size: Your choice of crank length.

X.P.S.S.™ (eXtreme Performance Shifting System), the acronym that refers to the most efficient system ever, lets you shift with extreme speed and incredible precision.

At first glance, the Chorus™ 2011 crankset does not show any changes. But actually there is plenty of news hidden behind the new look.
The chainrings have been completely redesigned. The new teeth design plus the new 8 ascending and 2 descending zones of the chainring enable top-class performance.

Features:

• 39-53T  (Standard groupset)
• Weight: 667g
• 34-50T  (Compact groupset)
• Weight: 667g
• Unidirectional and multidirectional carbon fibre
• light alloy screws
• 8 pins on the large chainring

Note: Record Ultra Torque BB cups: All supplied with your choice of British or Italian BB cups
(Ultra-Torque specific).

Chorus 11s Skeleton Brakeset:

The new compounds dramatically improve braking, and the new lighter pad holders make replacement easier and faster.
Skeleton design. This particular design makes it possible to eliminate the material in excess, thus reducing weightwhile maintaining the rigidity of the braking system unaltered and therefore the braking performance. Differentiated brakes- The front brake provides strong stopping power, while the rear brake serves to modulate braking and prevent the rear wheel from locking
Special compound of the pads- Developed in-house by Campagnolo, this compound has the merit of maintaining a virtually identical braking curve in both wet and dry conditions. Also guarantees excellent modulatability and a good service life.

Features:

• Orbital pad adjustment
• special pad compound
• Lightened Skeleton structure
• Weight: 299 g

Record Ultra Torque BB cups™ 

 BB cups: Supplied with your choice of British or Italian BB cups (Ultra-Torque specific).

• Weight: 49g
• Aluminium cups for use with all Ultra-Torque Chainsets
