Fly Like an Eagle

The X01 EAGLE™ Derailleur stands as the ultimate pinnacle in derailleur technology, showcasing a refreshed colour scheme and a novel approach compared to its predecessors. The X01 EAGLE™ excels in delivering flawless performance on command, unfazed by the challenges of uphill climbs or sprinting towards a stage victory. Its revamped cage design enhances chain management, ensuring precision in every shift.

Meticulously engineered to seamlessly integrate with the new 10-42T Cassettes while retaining compatibility with the 10-50T variations, the X01 EAGLE™ empowers riders to select their preferred cassette configuration. This flexibility allows riders to tailor their setup according to their preferences. Remaining faithful to the iconic X01 EAGLE™ colourway, the Derailleur perfectly complements other EAGLE™ components on the cyclist's bike, forming a harmonious visual ensemble.

From the racecourse to the camera lens, the X01 EAGLE™ Derailleur is poised to make a resounding statement. Its remarkable performance and aesthetic elegance make it a true standout in both competitive cycling and visual appeal.

Cage Lock

Experience swift and simple wheel removal and installation with the advanced Cage Lock technology in the rear derailleur. A mere push of the cage creates slack, effortlessly locking it in position.


Developed specifically for the SRAM 1x Drivetrains., X_ACTUATION keeps shifting sharp and consistent across the entire cassette.

Roller Bearing Clutch

The Roller Bearing Clutch technology eliminates derailleur bounce and chain slap, preserving precision without compromise.


Crafted with the "Straight Parallelogram" concept, this Rear Derailleur's movement is confined to the horizontal axis, preventing unintentional shifting and reducing shift force. The spacious upper pulley maintains a consistent chain gap across all gears, ensuring rapid and precise shifts.


EAGLE™ Technology heralds the latest in 1x drivetrain innovation, offering a lighter, simpler, and more durable system that's easier to operate. Packed with cutting-edge advancements, EAGLE™ is meticulously engineered for both performance and longevity, while also significantly reducing weight. A colossal 500% increase in range, equivalent to a 2x11 Drivetrain, sets EAGLE™ apart.


Welcome the evolution of X-Sync technology with SRAM X-Sync2 EAGLE™. Its aggressive teeth enhance chain retention, providing a smoother and more efficient pedal feel, all while prioritizing durability. The design also curbs friction and prevents the accumulation of debris like mud and grime.
