The technology to change your ride: Shimano XT Di2 2×11-speed M8050 Upgrade Kit internal

At the touch of a button you can now change gear with extreme accuracy, speed and precision. When the trail suddenly turns up hill, your DEORE XT drivetrain can now respond to your every demand. When your hands are aching from gripping your bars, a light touch of your Di2 button is all you need to move to a more efficient gear. And together with Synchro Shift technology, which adjusts your front derailleur and your chain line automatically, you´ll always have the right gear options to quickly switch between tough climbs, technical descents and pure-adrenaline racing.

The most groundbreaking technology featuring on DEORE XT Di2 M8050 though is a new wireless Bluetooth connection to Shimano’s E-TUBE program, which is the system Shimano uses to set up and control the Di2 shifting behaviour. Through Bluetooth technology riders or mechanics can wirelessly communicate with their computer, tablet or a smart phone via the SC-MT800 system information display and a new battery. As well as allowing wireless workshop customizability, it allows riders to customize their shifting preferences on the trail via an app on their smartphones.

Additionally, Shimano’s wireless D-FLY Data Management system will allow riders to see battery and gear information on their compatible third party display devices (eg bike computers). This technology will be rolled out with DEORE XT Di2 components and will be available as an upgrade for those currently riding Shimano XTR Di2, either with SC-MT800 or SCM9051 system information displays and a new internal or external battery.

Bluetooth LE
The most groundbreaking technology featuring is a new wireless Bluetooth connection to Shimano’s E-TUBE program, which is the system Shimano uses to set up and control the Di2 shifting behaviour. Through Bluetooth technology riders or mechanics can wirelessly communicate with their computer, tablet or a smart phone via the wireless unit (EW-WU101/EW-WU111)orthe system information display (SC-MT800/SC-M9051)and a new battery (BT-DN110) or battery mount (BM-DN100). As well as allowing wireless workshop customizability, it allows riders to customize their shifting preferences on the trail via an app on their smartphones.

The DURA-ACE 9070 and ULTEGRA 6870, XTR M9050, XT M8050 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.

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. Programmable synchronized shifting map – The rider chooses when front shifts occur and also chooses rear derailleur command.

• • Ergonomic rotary switch match natural hand movement -> Independent lever position adjustment

• • Faster and more accurate shifting -> Short-stroke, vivid index feeling

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.
