Highly versatile, this stunning model’s chain stabiliser prevents chain slapping and drops as you conquer every road. You’ll notice its silent and uninterrupted rear shifting on especially harsh terrains, where other rear mechs could struggle.

Featuring the revolutionary Di2 shifting system, this rear mech delivers instant, accurate, lightning-fast shifts on every run. At the push of a button, you can maintain precise control even in the most extreme conditions with its electronic brain keeping you in charge. Additionally, you can change gear even under heavy load while climbing or accelerating making it perfect for tough rides.
Smooth and reliable on mixed surfaces, its gravel-tuned clutch tension is ready to conquer all the challenges of a long ride out. Whether you’re riding after work with your buddies or exploring new and unpredictable surroundings, this 2x11 speed version won’t let you down.
