CHORUS 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.
FEATURES & BENEFITS
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.
Note: the medium cage derailler RD18-CH1M is required for use with the Campagnolo 11-32 cassette
