Shimano is bringing out new two XT Di2 drivetrain, the first update to the mountain bike electric shifting in years. But there’s a catch. The two derailleurs, which feature completely new shift capabilities, are designed for use with eMTBs. Free Shift and Auto Shift, two new Di2 shift modes, only work in coordination with an EP drive unit.
Shimano is also rolling out two new motors, the EP801 and EP6, as well as an all-new Cues Di2 shifter.
Next-gen eMTB features: Free Shift and Auto Shift
Free Shift and Auto Shift take advantage of having a motor and computer system integrated into an eMTB. Instead of just powering the bike, the new drive modes use the motor to make new shifting capabilities possible.
Free Shift
Free Shift lets you shift gears while coasting. It does so by integrating XT Di2 derailleurs and the motor. Shift while coasting and the EP6 or EP801 will advance the chain enough to shift gears. So, for example, when you’re cruising downhill, round a corner and see a big hill you can enjoy the descent and get in the right gear to get up the hill.
Auto Shift with Manual Override
Auto Shift takes integration to a whole new level. When engaged, the system will automatically shift gears for you, making predictive gear changes based on your speed and cadence. The goal is to let you focus on riding without worrying about finding the right gear.

Two XT Di2 derailleurs are arriving. An 11-speed XT Di2 LG, designed to work with Shimano’s Linkglide chain and cassette. And a more performance-oriented 12-speed XT Di2 HG+, designed for Shimano’s Hyperglide+ drivetrains. Both derailleurs are powered by the EP system’s centralized battery. Both derailleurs also work with either the new EP6 or EP801 motors.
There are a few differences beyond 11 versus 12 speeds. XT Di2 LG will let riders use all modes including full Auto Shift with Manual Override. XT Di2 HG+ only lets riders choose manual shifting, Free Shift, and auto shifting while…
