The Eagle AXS derailleur is the brain of the whole AXS system
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
Battery not included
The ULTEGRA ST-R8170 2x12 speed Dual Control levers with Wireless Di2 connectivity deliver a clean aesthetic and simple setup while reimagined ergonomics bring a new level of comfort and control.
