Shimano Ultegra RX800 11 Speed Rear Derailleur

The Shimano Ultegra RX R8000 Rear Derailleur GS offers reliable and durable 11-speed shifting to the discerning cyclist looking to explore the paths less travelled. Utilising Shimano's tried and tested Shadow profile, this aesthetically pleasing derailleur stays safe from impacts, while the wide outer link plate reduces shifting deflection to ensure quick and precise gear selection.

Compatible with cassettes between 11-28T and 11-34T, this versatile derailleur is perfect for undulating alpine adventures, while the lightweight aluminium pulley cage helps to reduce weight without sacrificing performance or reliability. Completed with the RX clutch system, the R8000 is suitable for mixed terrain use; maintaining chain tension and virtually eliminating unwanted 'chain chatter' no matter the surface below.
