Insightful.

With its SC-MT9051 Di2 Digital Display Unit, Shimano ushers its off-road electronic groupset into the wireless realm. The SC-MT9051 is Bluetooth compatible, so it displays all of the drivetrain information of its wired predecessor, the SC-M9050, but without the inconvenience of wired connections. It still enables Synchro Shift, but it now also lets you customize and fine-tune the Di2 shifting system wirelessly—once again courtesy of its Bluetooth connection.

The rapidly evolving world of electronic drivetrains can be confusing, compatibility-wise, so we'll help walk you through it. The SC-MT9051 is compatible with Shimano's BT-DN110 battery. It does also work with the SM-BTR2 battery, which is the previous Di2 battery built for the SC-M9050, but doing so negates the Bluetooth functionality and eliminates Synchro Shift. Given those limitations, we recommend only pairing it with the BT-DN110 battery.

  • For full functionality, pair with Shimano's BT-DN110 battery

I had the previous version of this unit but any time I wanted to change my shifting preferences I had to go to my LBS to make those updates because that is the only place that has Microsoft hardware, along with the library and goodwill.

Now I can pull out my phone or iPad, connect to this display unit and customize from there. I love SynchroShift and in my opinion Shimano makes the best shifting in the business. Never skips, moves smoothly, and with Synchro Shift I can hold down the shifter and move through gears seamlessly

Does this charge by using the charger from the bike? How does it turn on?

This connects to the Shimano BT-DN110 battery. When the battery is charged it's ready to roll. It only displays when you shift and within the ETube app you can select how long you want the display to stay on after you shift
