Built as part of the new Super Records 12 Wireless groupset, the Campagnolo Super Record 12 WRL Rear Derailleur brings us the reliable and fluid shifting we seek in a cable-free setup. Maximum shifting performance is delivered by a position sensor that allows the gear to position itself automatically in the perfect spot and is always optimized to recognize the sprocket currently positioned. In the anomaly that our derailleur gets stuck, the UnLock system allows for a manual move to the preferred position and protects the gears from damage during an impact.
