SRAM XX1 Eagle 12-Speed Rear Derailleur

Occupying a new realm in shifting performance, the redesigned XX1 Eagle™ derailleur gives no-compromise racers and dream-bike builders a true top-tier option. The crisp, precise XX1™ shifting feel athletes rely on now features an updated cage geometry for improved chain management. Occupying its rightful place at the top of the Eagle™ ecosystem, the XX1 Eagle™ rear derailleur makes full use of the new 10-52t cassettes and is backwards compatible to also work with the 10-50t.

Technology

Cage Lock

With Cage Lock technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just push the cage forward to create slack and lock it into place.

Roller Bearing Clutch

Roller Bearing Clutch technology eliminates derailleur bounce and chain slap without sacrificing precision.

X-Actuation

Developed specifically for SRAM 1x, X-Actuation keeps shifting sharp and consistent across the entire cassette.

X-Horizon

This rear derailleur’s “straight parallelogram” design limits all movement to the Horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

X-Sync

SRAM X-Sync 1x chainrings provide the highest level of performance and durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.

Eagle

Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.
