The EX1 derailleur capitalizes on the robust build and precise shifting attributes of the X-HORIZON design, to create the worlds 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.
