SRAM XX1 Eagle AXS 12 AXS Black Rear Derailleur

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.

• Ti hardware
• 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 IPX7
• Battery sold separately

TECHNOLOGIES

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.

AXS

• AXS is SRAM’s bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.

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 1 x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features 1 x 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 2 x 11 drivetrains.
