SRAM, X01 Eagle B2, Rear Derailleur, Speed: 12, Lunar

Elevating the shift, expanding the capable, the X01 Eagle derailleur features an updated cage architecture, to provide better chain management than ever. The X01 Eagle rear derailleur works with the new 10-52T cassettes and is backwards compatible to also work with 10-50T options. As part of the new Eagle Colorsystem, it comes in X01 Eagle signature colorway to go perfectly with any color cassette and chain a rider wants.

Features:

• Updated cage provides better chain retention and more precise shifts.
• Comes in X01 Eagle signature colorway as part of Eagle Colorsystem – to go with all cassette and chain color options - Black, Gold, Rainbow to HardChrome and all-new Copper.
• Backwards compatible, works with 10-50T and new 10-52T cassettes.

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.
