The Shimano Ultegra RD-R8000 Rear derailleur
The RD-R8000 rear derailleur creates a reduction in shifting effort at the lever, at the same time remaining sure, quick and precise. The groupset offers two specific rear derailleurs: one for cassettes 11-25 and 11-30 and one for cassettes 11-28 and 11-34, securing a smooth ride in even the highest and steepest mountain areas. Due to the integrated Shadow RD Technology with its race-proven, low profile design, the derailleur is more compact and fits closer to the frame, ensuring less damage in a crash.
Everything you need to make your ride distinctively yours.
The new Ultegra R8000 series is taking our rider-tuned philosophy to the next level, with an extensive range of components for mechanical shifting, electronic shifting (Di2) and time trial / triathlon.

SHADOW RD
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.
