Description
 
Shimano RD-RX805 Ultegra RX Di2 Rear Derailleur: The new RX800/805 rear derailleurs share many characteristics with the Ultegra R8000/R8050 derailleur, such as precise accurate shifting and SHIMANO SHADOW RD derailleur positioning, but with the added chain stabilizing switch (known as SHIMANO SHADOW RD+ technology) to control the drivetrain over rough/uneven ground or off-road surfaces. Much like Shimano’s MTB derailleurs the On/Off switch can be found next to the upper pulley. When activated the rear derailleur pivot takes a firm hold to reduce excessive movement, noise and general chain chatter.
