This ushers in the digital age for mountain bikers, giving them control over their ride experience, no matter their discipline, like never before.

    SEIS - Shimano Electronic Intelligent System
    The DURA-ACE 9070 and ULTEGRA 6870, XTR M9050 and ALFINE series have achieved a technological innovation of the computerized shifting system based on the Di2 concept with its new name, the 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. 

    Synchro Shift
    Two derailleurs, One Shifter - Front derailleur reads the rear derailleur’s position and automatically executes front shifts Improves efficiency by minimizing time spent on smaller chainwheels.

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.

    Shadow RD+ 
    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.
