Shimano Ultegra R8000 11-Speed Rear Derailleur SS

Accurate mechanical shifting developed to provide the rider with the smooth and reliable shifting pattern across their entire cassette, the Shimano Ultegra R8000 11-Speed Rear Derailleur SS is an easy means of equipping your bike with 11-speed compatibility and slick changing across cassettes ranging from 11-25T to 11-30T.

Benefitting from a lightweight aluminium pulley cage manufactured to provide you with the integral strength to shift with precision and accuracy whilst under load, this rear derailleur weighs just 198 grams whilst giving you the breadth to open up your gearing to conquer more. With a wide link design that gives quick and accurate shifting whilst improving your overall drive train efficiency, this derailleur benefits from a low, aerodynamic profile that also helps keep this rear mech from bearing the brunt of crashes, should they happen to occur.

An optimised slant angle and compatibility with 11-speed drivetrains improving the overall cohesion of this component and your bike, you can be sure of a slick operation from this mechanical rear derailleur. With a wide outer link plating increasing pivot joint rigidity, you can rely on a click and shift even when under load, allowing you to keep your rhythm and climb in style.
