Campagnolo Chorus 12s Front Derailleur

The precise, extremely fluid movement of the front derailleur is achieved in part due to the new cables and their housing and in part because of the design and construction of the 2x12-speed front derailleur.

The new Chorus derailleur incorporates a design that separates the upper from the lower semi-rod, eliminating the free stroke for more immediate, responsive upshifting. Design of the 2x12 speed front derailleur and its trajectory angle mean wide tires measuring up to 32mm can be used, while the new design of the cage and dedicated positions for each gear position ensure extremely precise and fluid derailleur performance. 

The derailleur cage is designed to improve maximum cross-chaining situations. Clearance for wider tires is provided, 32mm tires can be mounted without the risk of contact with the derailleur. Double-position fixing of the cable provides maximum compatibility with frames and tires.
