Shimano Ultegra RD-R8000 11-Speed Rear Derailleur

The Shimano Ultegra RD-R8000 is an 11-speed rear derailleur from Shimano’s Ultegra range. Its wide link design gives quick, accurate shifts and good drivetrain efficiency. Wide outer link plates make the pivot joints stiffer, which reduces shifting deflection.

The low-profile Shadow design gives the derailleur a sleek look and reduces the risk of damage in a crash. The pulley cage is aluminium, which keeps weight down without hurting shifting performance.

This version has a short (SS) cage. It works with a wide range of cassettes, from 11-25T up to 11-30T.
