Campagnolo Chorus 12s front derailler

The precise and extremely fluid movement of the derailed is partly obtained thanks to the new cables and their housings, and in part thanks to the design and construction of the 2x12 Speed ​​derailler.

The new Chorus derailler incorporates the same design that separates the upper semi-biella from the lower one, eliminating the empty race and giving a more immediate and reactive uphill derailed. The design of the 2x12 Speed ​​derailler and its trajectory angle allow the use of tires up to 32 mm wide, while the new fork design and the dedicated positions for each gear position make the derailler's performance extremely precise and fluid.
