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. 


E-Block - shifting technology is a fundamental redevelopment of external drivetrain shifting. On the E-Block cassette, the chain has a defined link position on each cog. Cog architecture has been engineered to work with both inner and outer links of the chain, which allows extremely refined shifting for both inboard and outboard shifts. The result is precise and robust shifting performance in any situation, even with full motor support.
