SRAM Force E1 Front Derailleur

The SRAM Force E1 Front Derailleur is engineered for riders who demand fast, precise, and silent front shifting in a modern 2x road drivetrain. Built around SRAM’s fully wireless AXS ecosystem, this derailleur eliminates cables while delivering consistent, high-performance gear changes under load.

Key Features & Benefits

Wireless AXS Integration
Seamlessly connects with the SRAM AXS ecosystem for clean cockpit aesthetics, real-time battery monitoring, and fully customizable shifting via the AXS app.

Yaw™ Cage Technology with Auto-Trim
The rotating cage design maintains optimal alignment with the chain across the cassette, eliminating chain rub and the need for manual trim—resulting in quieter, more efficient shifting in every gear.

Faster, More Precise Front Shifting
A refined, narrower cage reduces shift distance, improving responsiveness—especially during high-torque efforts and outboard shifts.

Optimized for X-Range™ Gearing
Designed to work perfectly with SRAM’s X-Range chainrings, providing smoother gear progression and tighter cadence control across modern road setups.

Simple Setup & Adjustment
Includes an updated setup tool and intuitive alignment design, making installation faster and more repeatable for mechanics and home builders alike.
