The new Sram EX1 groupset is designed to meet the demands of electric mountain biking. Buy at a special pre-order reduced price as a complete group set. Even more lucrative if bought with the Guide RE hydraulic disc brakes, being the only true e-bike optimised disc brakes out in the market place.

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. 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 purpose driven shifts and providing the best gear range for mid motor 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.

Please Note: The Sram EX1 Cassette fits onto a standard type casette body and not an 11 spd driver body.
