New 2024 Campagnolo RECORD 12S Rear Derailleur : RD20-RE124. Designed to improve performance and function in every aspect, the new Campagnolo Record 12 Speed mechanical rear derailleur has an innovative shape that envelopes the sprockets better thanks to 3D Embrace technology, creating a double effect: allowing the chain to maintain optimum traction at all times, thus increasing the speed, power and precision of shifting; and ensuring that the derailleur is always kept an optimal distance away from the sprockets. The cage has also been optimized to work with sprockets from 11 to 34 teeth, allowing a single version to be maintained for all available sprocket sets. The upper part of the new Record 12 Speed mechanical rear derailleur gearbox is made of carbon fibre-reinforced technopolymer, contributing to its robustness and lightness, while the stop adjustment screws at the back of the rear derailleur make adjustments very simple. Optimized to work with cassettes from 11 to 34 teeth. Carbon fiber-reinforced construction, to increase strength while keeping weight to a minimum. Optimized spring return for constant chain tension. Adjustment of the initial rear derailleur position. Removable pivot on the upper body. Rear Derailleur Mount Type: 10×1 Standard. Chain Wrap Capacity (teeth): 37 teeth. Rear Der/Shifter Compatibility: Campy 2019 12-Speed. NONSTOP CICLISMO is your source for top quality road cycling equipment.
