The new Sram EX1 rear derailleur for the complete EX1 eBike specific group set, designed to meet the demands of electric mountain biking.
The EX1 derailleur capitalises on the robust build and precise shifting attributes of the X-HORIZON™ design, to create the world’s first derailleur specifically made for E-MTBs.
Engineered to handle high-torque, low-cadence shifting across the 11-48 tooth E-BLOCK™ cassette, the EX1 derailleur gives E-MTB riders clean, confident shifts, so they can spend more time enjoying the ride.
- Proven SRAM X-HORIZON™ design that reduces shift force, ghost shifting and chain slap
- 12-tooth X-SYNC™ pulley wheels
- The EX1 derailleur is purpose built for E-MTB
