Shimano Ultegra RD-R8000 11-Speed Rear Derailleur

The RD-R8000 rear derailleur reduces the effort required at the lever while ensuring secure, fast and precise shifting. The groupset offers two specific rear derailleurs: one for 11-25 and 11-30 cassettes and one for 11-28 and 11-34 cassettes, ensuring a smooth ride even in the highest and steepest mountain areas. Thanks to integrated Shadow RD technology, with its race-proven low-profile design, the rear derailleur is more compact and sits closer to the frame, reducing damage in a crash.

Features:

• Compact, sleek appearance.

• Shimano Shadow RD.
• Race-ready.
• Short cage (RD-SS): recommended cassette from 11-25T to 11-30T.
• Actual weight: 199 g (SS)

Technology:

Shadow RD

Traditional rear derailleurs protrude beyond the bike's profile. With its low-profile design, Shadow RD is a more compact rear derailleur that sits closer to the frame, with more direct cable routing. Shadow RD maintains a constant distance from the cassette to increase shifting stability. Its narrow body gives it a sleek, clean appearance while reducing damage in a crash.
