Shift Sensor-for Derailleurs and Internal Hubs


New ENA-GS-EX version now available

The NEW Gearsensor (for derailleurs and Internal Hubs) used with the Bafang mid drives BBS01/02 and BBSHD to cut motor power while shifting.  Connects into one of the brake connectors or, on some of the newer Bafang mid drives, an extra 4th cable from the controller. Stops heavy torque “slamming” of the chain.
