SRAM Rear Derailleur EX1 1x8 Speed Long Cage Black (Max 48t)

The EX1 derailleur capitalizes 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

14-tooth X-SYNC™ pulley wheels

The EX1 derailleur is purpose built for E-MTB
