Sram Rear derailleur EX1

The EX1 derailleur relies on the robustness and precision of construction of the X-HORIZON™ to create the world's first derailleur specifically designed for electric mountain bikes.
Designed to handle gear changes at low cadence and high torque on the 11-48 tooth E-BLOCK™ cassette, the EX1 derailleur provides electric mountain bike riders with clean and safe shifts, allowing them to spend more time enjoying their ride.

The proven SRAM X-HORIZON™ design reduces the force required for shifting, minimizes unintentional gear changes, and prevents chain noise.
