Rear Derailleur 11 Speed Shimano Ultegra RD-R8000

Experience premium, stress-free operation on all-day epic rides.

Direct from the professional peloton, the Ultegra R8000 short cage (SS) derailleur features a complete trickle-down of technology from Shimano’s flagship Dura-Ace groupset.

Now re-engineered with the low-profile Shimano Shadow RD layout, it tucks closer to the frame to protect the derailleur from crash damage while delivering lighter, more precise shifting effort at the lever.

Key Features

• Shimano Shadow RD Design: Low-profile architecture keeps the derailleur out of harm’s way while ensuring aerodynamic, stable shifting.
• Pro-Proven Heritage: Technology directly inherited from Dura-Ace for effortless, reliable gear changes under any riding load.
• Featherweight Construction: Coming in at an approximate weight of just 200 grams, it is the perfect upgrade for weight-conscious road cyclists.
• Crisp Road Geometry: Short cage design optimized for standard road race gear ratios up to a 30T low sprocket.
