Product details

The EX1 derailleur is based on the robustness and precision of the X-HORIZON to create the world's first derailleur specifically designed for e-mountain bikes. It is engineered for shifting at low cadence and high torque on the 11-48 tooth E-BLOCK cassette. The EX1 derailleur allows e-mountain bikers to enjoy clean and secure gear changes, enabling them to spend more time enjoying their ride. The proven SRAM X-HORIZON design reduces the effort required for shifting, unexpected gear changes, and chain chatter.
