Product description

The RX805 rear derailleur is compatible with road dual control levers (Di2) and will accommodate cassettes with low gears from 28T to 34T, making them a very necessary addition for all types of adventure and off-road riding including cyclocross and compact styles with 46T-36T up to 50T-34T chainrings.

For adventure, gravel and cyclocross use: Shimano Ultegra Di2 2x11-speed Rear Derailleur RD-RX805 GS

Riders have been pushing the limits of what a road bike is capable of riding for many years, evolving the sport from racing to encompass greater adventure. In recent years we’ve seen a broader definition of what a drop handlebar bike can look like; road wheels followed that by accommodating wider tyres. Now in a natural evolutionary step it’s time for drivetrains to evolve too.

The new RX800/805 rear derailleurs shares 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’.

SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEM

The SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances like when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Levers so you don’t need to re-program your mind for a new system.

E-Tube

E-Tube platform offers optimum flexibility on your bike. E-TUBE transmits interactive signals and power supply to each parts by “Plug & play” connection. E-TUBE is no rust, no stretch, no freeze and it ensures advanced low maintenance. And SM-PCE1 connects between PC and components to update firmware. Digital device stay the latest version with updating firmware for improve function.

Synchro-Shift

SHIMANO Synchronized Shift is a new feature introduced to Shimano´s electronic road groupsets, designed to simplify gear choice and reduce decision making in racing situations. When riding at maximum capacity, decision making can be impaired. The less stresses on a rider and the less decisions a rider has to make, the less mistakes they will make. Therefore SHIMANO Synchronized Shift is designed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur.

Two SHIMANO Synchronized Shift modes will be available:

Full SHIMANO Synchronized Shift: the front derailleur reacts based on the rear derailleur’s shift action. This essentially means that, when activated, there is no need for two separate shifters to control front and rear derailleurs, the two buttons on one shifter will control both derailleurs.
Semi SHIMANO Synchronized Shift mode: the rear derailleur reacts based on the front derailleur’s shift action, shifting to the next most appropriate rear gear when the rider makes a front shift.
