The new Campagnolo Chorus 12-speed rear derailleur reaps the benefits of 12-speed trickle-down, incorporating the sophistication and precision of Record and Super Record at a fraction of the cost.
The rear derailleur now sports Campagnolo's Embrace geometry, which provides more chain wrap and more consistent sprocket-to-pulley dimensions across the cassette than before, as well as a single cage length that works across every available Campagnolo 12-speed cassette. Both the upper and lower knuckles are molded from fiber-reinforced technopolymer, while the parallelogram links and derailleur cage are made from forged aluminum.
3D Embrace technology places the 12-tooth pulley wheel closer to the bottom of the cog, increasing the chain engagement and management over rough roads and more precise and faster shifts.
