The new SUPER RECORD WIRELESS derailleur introduces shifting with Bluetooth technology, with smooth and instantaneous communication between the derailleur and controls: wireless. Every little detail has been optimized for maximum functionality with a user-centric approach. The quick-snap magnetic charging ports, the vibrant color of the battery LEDs, and super-fast charging allow for easy and hassle-free use and recharging. The new design of the mechanical components ensures smooth, efficient, and reliable shifting. The precision of the derailleur’s motor allows the chain movement between gears to become not only immediate but also extremely smooth even in situations of maximum load applied by the cyclist. Thanks to the internal aluminum semi-fork and the monolithic external carbon fiber semi-fork, the Super Record EPS derailleur performs shifting functions with maximum rigidity and efficiency.
