Shimano Deore XT gets Di2 technology

Sitting between the granite-hewn professional racers and the weekend warriors you’ll find a group of highly competitive and highly skilled mountain bikers. These are the privateers and the self-supported riders. These are the riders who put the hours in to keep themselves race-fit and have the skills to test themselves against the best. These are the amateur mountain bike racers. And these are the riders Shimano had in mind when it developed DEORE XT Di2 M8050.



If you’ve dreamt of winning races, if you’ve sent in a race application and started to wonder if you’ve got what it takes, if you’ve pinned on race numbers and glanced enviously at the other riders’ bikes then you know what the trail to triumph involves. If you crave the latest components in search of the technology to change your ride, then the answer is Shimano DEORE XT Di2 M8050.


The technology to change your ride

Two years after launching the world’s first commercially available mountain bike electronic shifting system, Shimano brings the power and the technology to drastically change the way you ride to DEORE XT level.


At the touch of a button and with just one lever 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.



Much like the Shimano DEORE XT M8000 mechanical derailleur, the DEORE XT Di2 M8050 rear derailleur also includes Shadow RD+ technology, which is designed to eliminate chain bounce and keep chains on sprockets over multiple types of terrain, leading to a more stable shifting platform.


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.


The components of adventure

In terms of the components themselves, it’s the drivetrain where DEORE XT Di2 M8050 developments have focused.


SW-M8050 front and rear FIREBOLT shifters are designed to provide easy operation and accurate shifting with an ergonomic rotary action, short single-click action and effortless multi-shift possibilities. The FIREBOLT shift button placement is customizable and can be positioned exactly where the rider’s thumbs naturally rest. This allows you to shift faster and match your efforts like never before.


The SYNCHRO SHIFT technology inherent in the shifters means riders can rely solely on one shifter to take care of their rear and front gear changes. A customizable shift map means riders can program the exact gear ratio at which Di2 automatically shifts into the big ring when going up through the gears, or into the small ring when going down through the gears. Whichever gear ratio you choose, Shimano’s Rhythm Step philosophy ensures that riders make the minimum amount of incremental steps when changing up or down gears, allowing the rider to maintain an even cadence and fluid riding style. No large gear steps, no over-working joints and muscles, just effortless pedaling throughout the gear range. No compromises, just a focus on simplicity and enjoyment.




The shifters are designed to work in harmony with the SC-MT800 system information display, the RD-M8050 rear derailleur and the FD-M8070 front derailleur. Not only does the SC-MT800 system information display give a visual display of the rider’s gear and battery level, but it is also the control point for operating the trim adjustment and reboot function and wirelessly adjusting the multi-shift speed and SYNCHRO SHIFT operation via computer, tablet or smart phone.


The FD-M8070 front derailleur and RD-M8050 rear derailleur retain the accurate and stable shifting developed for XTR Di2 components. Computer-controlled auto trim on the front derailleur keeps the drivetrain running smoothly. Meanwhile, at the rear, changes are seamless, even under high loads, on steep inclines or when cassettes are more mud than teeth. The derailleur motors are twice as powerful as those on Dura-Ace and Ultegra Di2 to give precise shifting in difficult conditions.


Battery performance is identical to that of its big brother, XTR Di2, giving a minimum of several hundred kilometres of power under heavy usage (eg lots of shifting over three chainrings plus control of ancillary devices). The visual LED display indicates battery charge and the LED screen shuts off after a few seconds of inactivity to save battery life. If you do find yourself running low, charging the battery takes around 90 minutes and internal batteries work on a simple plug and play operation so can be easily swapped.




Durability is also in line with XTR Di2 components. A sealed, waterproof system means DEORE XT Di2’s electronic signals will stand up to mud, water and dirt from the worst of winter. Plus, with no worrying about cross-chaining, cable stretch, or cable adjustments, your gear changes will be incredibly consistent.


Shimano DEORE XT Di2 components will be available from September 2016. Get ready for the trail to triumph.

Nice . . . :thumbup:


But there is no end to the "new stuff" in the SRAM vs Shimano war these days. 


Hell . . .  I'll just stick with my old SS  . . . .. FFS :mellow:

I have a hard enough time keeping track of the battery on my Garmin. But I must say that never having to replace a shift cable again is quite enticing. I wonder if the next big thing after Eagle from SRAM will be an Etap Eagle.

As expected the frigging morons can't provide a 2 by or 1 by total cost. Yes I can add

The battery apparently last about 4 - 6 months, so it hardly needs to be on your mind very much.

Opposite direction of my MTB evolution.

Its still too expensive, exlectornic shifting is great and all but not at that premium.

jimmy hardtail, Apr 14 2016 09:40

What happens at a river crossing, does your bike suddenly electrocute you?

raptor-22, Apr 14 2016 09:43

soon, patience please

splat, Apr 15 2016 07:46

The XTR didn't excite me because of the cost, and even though this will also be expensive, I am filled with a need and a want. And a bit of lust...

BenGraham, Apr 15 2016 10:46

Wait a minute, $150 dollars for the display. Seriously. A digital display for around R2250. Thats mental and the rear derailieur R4500ish. Shimano have lost their minds. Your rear derailuer is first in line to take a beating from a rock and die just like that. I for one would be too afraid to ride my bike with this kit on. I've broken 3 rds could be 4 I'm not sure. That an insane amount of money. No thanks. This money would be far better spent on a frame or a fork, something that won't explode when a rock gets kicked up or you cut too close to a boulder.

BenGraham, Apr 15 2016 10:54

So converted the pricing for a lark. Absolutely mental. Yes Zuma is making this worse but even at R10 to the Dollar it would be crazy.


Front derailleur: $189 - R 2743.36
Rear derailleur: $293 - R 4252.94
MT800 digital display: $150 - R 2177.27
Single shift lever (for 1×11): $110 - R 1596.67
Two shift levers (for 2×11): $220 - R 3193.33
3x E-Tube wires: $70 - R 1016.06
Battery: $150 - R 2177.27
Junction box (for 2x): $29 - R 420.94


So a 1X11 setup without cassette, crank, chainrings, brakes, rotors, will cost you R 11 641.15. 2X11 will up that figure significantly. The XTR crowd might not see this as expensive but as a devotee of SLX I think this is crazy.

Is the digital display "compulsory" ?

Is the digital display "compulsory" ?

I saw a comment on a different website saying that with the wireless connectivity, you don't need the digital display because it would come up on your compatible Garmin.


Not sure if that is correct, because I understood that the display doubled up as the brain box which included the charging port etc.

Why no setup that does away with a brain and has a single shifter, battery and RD. Finish en kla!


1x11 would be such a win with that. I seriously do not understand how that could be difficult. also.... USD 150 for a battery.... and USD 110 for 2 buttons in a casing..... seems a bit ridiculous.
