Derailleurs

SRAM's XX1 Ceramic Bearing Rear Derailleur Pulleys run on super-smooth, efficient ceramic bearings so your drivetrain rolls with ease. They are lighter than conventional pulleys and even come with SRAM's ceramic-bearing grease in an easy-to-use 10ml syringe.

More than a mechanical derailleur with a battery and a motor bolted on, the Eagle AXS derailleur is the heart of the whole AXS system. It features a shorter cage for 10mm more ground clearance, with more chain wrap on the cassette to sit slightly further forward, and further inboard from mechanical Eagle. Instantaneous shifts from a single touch even while under World Cup-winning chain loads recorded in the heat of racing and affirmed in the test lab. Tested to IP69K water and dust proofing standard so whatever race day brings, you’re ready. - XC focus and trail ready - Carbon cage - Ti hardware - Rainbow colorway - Eagle technology - Overload Clutch protection - AXS enabled componentry software that makes it possible to both program and personalize new SRAM and RockShox components - System is completely water and dust proof to IP69K - Eagle AXS is designed to work with X-DOME Eagle cassettes only, providing the most precise, silent, and reliable shift performance available. - Battery sold separately

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 backward-compatible with 10-50T cassettes, as well. - 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 - Backward-compatible with 10-50T cassettes, works with new 10-52T cassettes

This one takes all your trail dreams, from XC to enduro, all the way to eleven. SRAM's XX1 rear derailleur packs a massive amount of technology into its compact, lightweight body. It uses a “horizontal parallelogram” design that limits all movement to the horizontal axis, reducing the force it takes to shift. The Type 2 clutch is brilliant. This self-lubricating, one-way roller clutch controls your chain tension to eliminate chain slap and give you smooth, consistent shifts over any terrain. For quicker, smoother, more exact shifting, the large upper pulley's offset design maintains a consistent chain gap across all gears.
