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.
Campagnolo have also made a created a completely new design for both the internal and external components.
Using new aluminium bolts, Campagnolo is able to reduce the weight by 53% compared to steel and 22% compared to titanium and this also prolongs the component life.
The new external shape enables the rear mech to move at a different angle, and the internal design keeps the chain nearer to the cassette to ensure better power transmission.
A carbon front plate and cage means maximum rigidity, fast actuation and reduced friction.
