SRAM XX1 Eagle rear derailleur 12 speed lunar

Soaring at the highest altitude of SRAM`s expanded, deeper, and more capable Eagle ecosystem, XX1 Eagle is the group for top-tier race bikes and absolute dream builds. Pro level performance and compatibility with all Eagle gear ranges, the XX1 Eagle drivetrain remains incredibly quiet, intuitive, and precise.

With enhanced chain retention performance courtesy of a new derailleur cage architecture, XX1 Eagle remains perched atop the pinnacle of MTB drivetrains. With a boost in aesthetics to match its status - XX1 Eagle launches their sophisticated Eagle Colorsystem. Shifter, cranks and derailleur all get the same XX1 master colorway, and can be paired with any color chain and cassette to enhance the look of the bike - from Black to Gold to Rainbow and all-new Copper. XX1 Eagle is still the lightest group in the Eagle ecosystem and now features an expanded 520-percent gear range option thanks to SRAM`s all-new 10-52t cassette. With the choice of added gear range, athletes can spend more time in the gear they want, and stronger riders are able to choose larger chainrings for more top-end speed, without sacrificing climbing range.

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.

• Updated cage geometry provides better chain retention and crisper shifting
• Comes in XX1 Eagle™ master colorway as part of Eagle™ Colorsystem - to go with all cassette and chain color options - Black, Gold, Rainbow, HardChrome and all-new Copper
• Backwards compatible, works with 10-50t and new 10-52t cassettes

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 500%, which is equal to 2x11 drivetrains.
