SRAM XX1 Eagle AXS Type 3 X-HORIZON Rear Derailleur 12-speed - black

More than a mechanical derailleur with a battery and a motor bolted on, the Eagle AXS™ derailleur is the brain of the whole AXS™ system. Trim it at set-up for zero rub, making the near-silent operation of Eagle™ even more quiet—all while improving drivetrain longevity.
It features a shorter carbon 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.
And of course it features SRAM's proven, 1x-specific X-HORIZON™ design. Large X-SYNC™ lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle's overall smooth-pedaling feel. The SRAM XX1 Eagle AXS™ derailleur uses both Type-3 roller bearing clutch and Overload Clutch. Type 3 roller bearing clutch is used to control cage movement and chain management. The Overload gearbox clutch protects the derailleur’s wireless motor in the event of impact. The CAGE LOCK™ function allows for an easy servicing. A robust mounting system further improves the Eagle™ derailleur's performance and overall durability. Thanks to titanium hardware the weight could be reduced to XC Worldcup level.

A bit about the battery

Yes, Eagle AXS™ uses a battery. One that is removable for easy recharging after 20 hours of ride time*. One that only weighs 25g and is detachable with a single clip. One that is "hot swappable"" if needed—from derailleur to your Reverb AXS™ seatpost or even your SRAM RED eTap AXS™ road group. And it only takes an hour to charge.

Notes:
Derailleur compatible with Eagle™-Cassette 10-52 teeth only.
The Eagle AXS™ system is completely water and dust proof to the IP69K international standard.
