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.
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.
Please note: This item is only compatible with SRAM EX1 E-MTB components.
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.
Developed specifically for SRAM X1, X-ACTUATION™ keeps shifting sharp and consistent across the entire 10-42T cassette. Multi-adjustable trigger shifter. MatchMaker X compatible.
ROLLER BEARING CLUTCH™ rear derailleurs deliver maximum drivetrain stability-even through the most punishing terrain. With ROLLER BEARING CLUTCH™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.
With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation-as well as chain installation-becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.
SRAM X-SYNC™ provides the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.
