Shimano today announced that Di2 will now be available in the Shimano XT level. This means that expensive technology previously only available in XTR will now be within reach of many consumers.

In addition, the XT and XTR Di2 systems can now be configured with a tablet or smart phone. Previously, it was only configurable with a wired connection to a Windows PC computer. This welcome development will make the flexibility of the Di2 system much more accessible to most users.

The shifter has also been improved on the XT system to make the two triggers more distinct from each other in terms of location and reach. This seems to bring the shifters more familiar to existing mechanical trigger users.

Shimano Deore XT M8050 Di2 electronic shifting integrates with Deore XT M8000 mechanical components in either a 1x11 or 2x11 drivetrain configuration. With increased precision, efficiency and customization of the Di2 electronic system, the original mountain bike component group reinforces its legacy of premium performance and value.

Deore XT Di2 FD-M8070 Front Derailleur / RD-M8050-GS Shimano Shadow RD+ Rear Derailleur

The new Deore XT Di2 M8050 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.

For riders who want expanded gear range while maintaining a simple rider interface, Shimano Synchronized Shift mode controls both derailleurs via a single Di2 Firebolt shifter. The system selects efficient gear combinations between the front and rear so riders just concentrate on pedaling and controlling the bike.

The rear derailleur can handle up to a 46-tooth cog.
