The Shimano Deore XT Di2 SC-MT800 is the nerve centre of any M8050 Di2 drivetrain, combining a system information display with Junction A connectivity, a dedicated charging port, and integrated wireless communication — all in a 30g unit that mounts directly to your handlebar.

Highlights

• At-a-glance system status: Displays current gear position (front and rear), battery charge level, shift mode, and FOX iRD suspension position in a single clear readout.
• Integrated Junction A: Three E-Tube SD50 ports connect your Di2 derailleurs, shifters, and other E-Tube compatible components through a single hub — no separate junction box required.
• On-board charging port: Accepts the SM-BCR2 charger directly at the display, keeping wiring tidy and charging simple.
• ANT+ and Bluetooth LE: Broadcasts gear and battery data to compatible head units via ANT+, and connects to smartphones and tablets via Bluetooth for E-Tube Project customisation.
• D-Fly compatible: Works with D-Fly wireless protocol for seamless integration with supported cycling computers and GPS devices.
• Synchro-Shift support: Functions as the control centre for configuring and managing Synchro-Shift and Multi-Shift modes via the E-Tube Project app.
• Audible shift notifications: Chimes confirm successful gear changes without the need to look at the display.
• Handlebar clamp options included: Supplied with both 31.8mm and 35mm clamps to suit modern MTB cockpit standards.

System Control & Customisation

The SC-MT800 is the primary interface for configuring your M8050 Di2 system. Using the E-Tube Project app on a smartphone or tablet, riders can set shift maps, configure Synchro-Shift pairings, adjust multi-shift steps, and update firmware — all over Bluetooth LE. ANT+ forwards real-time gear position and battery data to compatible Garmin, Wahoo, and other head units. A single button on the display lets you switch modes and access trim adjustments on the trail without unlocking your phone.
