Not everyone needs the added chain retention of a clutch derailleur. For those riders, we offer a non-clutch version of our innovative ADVENT derailleur. Without the clutch in the system, the shifting effort at the lever is reduced. While still capable of handling an 11-42T cassette, the rear derailleur is the perfect choice for commuter or touring bikes that can benefit from using a wide-range gearing system. - Direct cable routing for smooth and responsive shifting - No clutch for ultra-smooth shifting - Compatible with 11-42T 9-speed cassettes - Compatible with ADVENT shifters only

It's an all-new derailleur that's specifically designed and optimized to be motor-driven instead of cable-actuated. AXS powered components enable customization and scale to an individual rider's liking via the AXS App. 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. The Eagle AXS derailleur is smart enough to protect itself thanks to its incredibly resilient Overload Clutch. In the event of an impact, the motor gearbox disengages, giving the derailleur freedom to move, and instantly returns back to its position for a seamless experience for the rider. The system is tested to IP69K water and dust proofing standard for creek crossings, mud splatterings and the resulting post-ride pressure washings. - Enduro focus and trail ready - Forged aluminum cage - Stainless hardware - Black/Polar colorways - 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.
