Campagnolo Chorus 2/12-speed groupset road non-disc

Chorus

Introduction of the Chorus 12-speed groupset is a further example of high-performance transmission specifically for an already large group of users wanting a top level yet versatile product. Those who appreciate Campagnolo top-of-the range functionality have always loved the Chorus model for its excellent price-performance ratio.

No compromises have been made in this extension of the characteristics and main advantages of Super Record and Record 12-speed groupsets to the new Chorus 12-speed. In addition to this, the Chorus model also comes with the brand new Ultra Torque 32/48 crankset, together with the new 34/50 and 36/52 chainring combinations and the new 165 mm crank length. The combination with 11-29 / 11-32 / 11-34 dedicated cassettes makes Chorus the ideal groupset for those wanting a multi-purpose cycling experience.
