The DEORE XT M8050 Di2 derailleurs blend powerful performance with precise shifting that remains crisp and consistent over time. Featuring auto trim technology and an optimized cage design, the DEORE XT Di2 front derailleur tracks the movement of the rear derailleur and delivers perfect shifts from every gear combination. The Shimano Shadow RD+ low-profile geometry and chain stabilizer ensure drivetrain security while the electronic wire transmission maintains consistent performance in all weather and trail conditions.

SEIS - Shimano Electronic Intelligent System
The XT M8050 has achieved a technological innovation of the computerized shifting system based on the Di2 concept with its new name, the SEIS (SHIMANO ELECTRONIC INTELLIGENT SYSTŪRES IZNESUMI
). The SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTŪRES IZNESUMI
(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 dont need to re-program your mind for a new system.
Two derailleurs, One Shifter - Front derailleur reads the rear derailleurs position and automatically executes front shifts Improves efficiency by minimizing time spent on smaller chainwheels. Programmable synchronized shifting map - The rider chooses when front shifts occur and also chooses rear derailleur command.
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.
Less distraction quiet drive train. Rear Derailleur Stabilizer reduces chain slap. Simple solution for chain drop. Lighter and more efficient than roller type chain device.
In order to ensure proper functioning of the electronic Di2 drive system, all components require the same firmware version. The optional diagnostic device allows for reading out or updating the firmware version. An operation of components with different firmware versions may cause a malfunction or loss of function.
