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.
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.
Completely new design:
The new Chorus HO (Hydrualic Optimized) rear derailleur offers the level of quality of the Record series in an affordable package, and a better chain/sprocket interface and greater durability of components subject to wear and tear.
