SRAM X01 Eagle AXS Rear DerailleurIt' an all new derailleur that' specifically designed and optimized to be motor driven instead of cable actuated. AXS powered components enable customization and scale to an individual rider' 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
