RD-R8000 Ultegra 11-Speed Rear Derailleur

The Shimano Ultegra R8000 11-Speed Rear Derailleur, GS offers premium and precise shifting for 11-speed systems. This mechanical unit provides enhanced security and adjustment, making it ideal for riders seeking a wide range of gearing and the ability to easily repair and re-index on the roadside.

Designed for your 11-speed groupset, the Shimano Ultegra R8000 Rear Derailleur features a lightweight aluminium pulley cage, reducing weight without compromising shifting power or performance. With a broad gear ratio range of 11-28T to 11-34T, it equips you to tackle even the toughest climbs.

Its accurate shift pattern is enhanced by a low-profile Shadow design, which keeps the derailleur tucked out of harm's way, minimizing the risk of damage during rides or races. The wide outer link plate increases pivot joint rigidity, reducing shifting deflection and ensuring precise gear changes. Additionally, an easily adjustable barrel on top allows for quick indexing, making this derailleur perfect for performance riders who need reliable and easy-to-fix components.
