The heart of the Record 11 drivetrain! The Record rear derailleur is designed for the success of the greats in cycling, and even today it offers the pros the security of a fast and safe shift at all times - even under load. But you don't have to be a professional to enjoy the performance of the Record 11-speed circuit: everyone can enjoy it.
Totally renewed design
The new shape of the external components allows the rear derailleur to move at a different angle. The new interior design keeps the chain closer to the sprocket package, ensuring better power transmission, stronger and safer traction, better chain/sprocket connection and better durability of components subject to wear.
The special gear inside the rear derailleur body (which acts on a spring with a rectangular cross section) allows the component to move along a path that follows the curve of the sprockets exactly, on cassette 11-23 teeth and as on the new 11-29 cassette.
Parallelogram with Ultra-Shift Geometry
Maximum rigidity of the rear derailleur, fast shifting, maximum precision, minimum play.
Carbon Fibre Cage
Carbon fibre cage: High rigidity for precise positioning - lowest weight.
Shift rollers with ceramic balls
Lowest friction and maximum smoothness increase the service life and performance of the shifting.
