Campagnolo Chorus Rear Derailleur

Chorus 11-speeds shifting is very comparable to 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 helps to lower the price with sacrificing performance. All three groups share an improved shape, geometry and a two-piece aluminum fixing bolt. The new two-part system makes it possible to reduce the weight by 53%25 compared to steel and 22%25 compared to titanium and prolongs component life.New rear derailleur geometry combined with Embrace technology enables the rear derailleur to move along an improved path that keeps the chain closer to the cassette. This ensures better contact with the cassette and chain for a more solid power transfer and greater durability of the cassette and chain. Embrace Technology consists of small gears that engage with each shift to provide absolute precision when shifting. Campy claims that this advanced trajectory perfectly follows the curve of the cassette. This places the chain closer to the cassette in all gears from 11-23 to 11-29 for snappier shifts with zero hesitation. A special cog is positioned inside the derailleur body which embraces a rectangular section spring that precisely indexes each shift.
