Best Price Guaranteed SRAM EX1 – X-HORIZON – Rear Derailleur for E-Mountainbikes – 8-speed – Black

Ever since the first beat-up old newsboy bikes were modified to ride in the dirt, mountain biking has been about defying convention and finding new ways to make the ride better. And each new style of riding requires a perfect solution. EX1 is the world’s first drivetrain system specifically developed for the unique demands of the E-MTB. With proven SRAM 1x™ technology as its DNA, this group’s heart is the EX1 cassette, which allows optimal steps between cogs for more purposedriven shifts and providing the best gear range for midshipmotor E-MTBs. Each EX1 component is engineered to perfectly complement the system, and the result is quiet operation, intuitive shifting, increased battery life and greater durability. EX1 opens the door to a brave new world of mountain biking.

EX1 X-Horizon™ Rear Derailleur

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
• 12-tooth X-SYNC™ pulley wheels
• The EX1 derailleur is purpose built for E-MTB

Please note: This item is only compatible with SRAM EX1 E-MTB components.

X-HORIZON™

The X-HORIZON™ rear 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.
