The Ultegra R8000 11-Speed Rear Mech reduces shifting effort at the lever whilst retaining a quick and precise response at the rear. Featuring integrated Shadow RD Technology with its race-proven, low-profile design, the rear derailleur is more compact and fits closer to the frame, ensuring less damage in a crash.

Features: 

• Shadow RD Technology Traditional derailleurs extend wider than the profile of your bike. With its low-profile design, Shadow RD is a more compact derailleur that fits closer to the frame, with more direct cable routing. Shadow RD maintains a consistent distance to the cassette for increased shift stability. The reduced body width creates a sleek and smooth appearance, ensuring less damage in a crash.
