Sram's new 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.

Features:

• 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

Technologies:

Roller bearing clutch:

Roller bearing clutch eliminates derailleur bounce and chain slap without sacrificing precision.

X-Horizon:

This rear derailer "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 upper pulley offset design maintains a constant chain gap across all gears.

Specs:

• Cable pull ratio - 1:1
• Speeds - 8s
• Cage material - Aluminium
• Max Tooth - 48
