The Dream.

Introducing Eagle Transmission, the revolutionary mountain bike drivetrain system developed by SRAM after 6 years of refining their Eagle system and 11 years of dedicated 1x drivetrain innovation. Designed to enhance the riding experience, SRAM rethought the entire interface between the frame, wheel, and drivetrain to create a first-of-its-kind approach that sets a new standard for the industry.

Eagle Transmission has been engineered to meet the demands of the world’s most discerning riders. It uses the wheel axle itself as a universal constant, resulting in a wireless, fully integrated, and interdependent transmission system that simplifies, strengthens, and extends the lifespan of your drivetrain. Unlike traditional systems, Eagle Transmission requires no derailleur hanger or adjustment screws. It revels in performing under pressure, allowing you seamless shifting even under maximum power.

With Eagle Transmission, SRAM has dropped a seismic shift on what it means to shift a mountain bike. It is a radically robust system that raises the bar and sets new expectations for the entire mountain bike drivetrain industry.
