Di2 technology lands at DEORE XT level
Togoparts Editorial Team – 18th Apr 2016
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.
