This is the Campagnolo Chorus 11-Speed Carbon Rear Derailleur. Chorus™ 11-speed's shifting precision is comparable to its older 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 favourable 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.
QUICKLY TAKE THE LEAD AND LEAVE YOUR RIVALS MOTIONLESS:
The Ultra-Shift™ control by Campagnolo® is regarded by everyone as the fastest and most precise.
Thanks to the Ultra-Shift™ patented system; you can move the chain simultaneously up 3 sprockets and then 5 down.
Furthermore, the lever design allows for an ever lighter shifting, whilst maintaining the "click" sound featured on all Campagnolo® controls.
The Ultra-Shift™ system is featured on 2011 Super Record™, Record™ and Chorus™ 11 Speed groupset ranges.
REAR DERAILLEUR FIXING BOLTS IN ALUMINIUM:
With the same resistance and stiffness, the new two-part system makes it possible to reduce the weight by 53% compared to steel and 22% compared to titanium and prolongs the component life.
ULTRA-SHIFT™ EXCLUSIVE GEOMETRY PARALLELOGRAM:
Maximum derailleur stiffness, fast shifting, precision, reduction of possible play.
COMPLETELY NEW DESIGN:
The new shape of the external components enables the rear derailleur to move according to a different angle and the new internal design keeps the chain nearer the cassette to ensure better power transmission, greater and more secure traction, a better chain/sprocket interface and greater durability of components subject to wear and tear.
The special chainring positioned inside the gear body acts on a rectangular section spring that allows the component to move along a trajectory that perfectly follows the curve of the sprockets, on both the 11-23 cassette and the new 11-29.
FRONT PLATE AND CAGE IN CARBON FIBRE:
Maximum rigidity, fast actuation and reduced friction.
