SRAM EX1 8-speed eBike Rear Derailleur

• Cable Pull Ratio: 1:1
• Speed: 8
• Color: Black
• Cage Material: Aluminum
• Pulley Bearings Material: Steel
• Max Tooth: 48
• Proven SRAM X-HORIZON™ design that reduces shift force, ghost shifting and chain slap
• 14-tooth X-SYNC™ pulley wheels
• Purpose built for E-MTB
• Roller Bearing Clutch: This technology eliminates derailleur bounce and chain slap without sacrificing precision
• X-Horizon: The derailleur's straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

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.
