FIREBOLT Technology

The FIREBOLT lever geometry is engineered to match the natural arc of your fingers, requiring minimal effort for a positive shift signal. The short throw gives immediate tactile feedback — a vivid index feel that confirms each shift is registered — so you can focus entirely on the trail ahead.

E-TUBE Programmability

Connect to the Shimano E-TUBE PROJECT via Bluetooth to customise this switch's function to suit your riding style. Assign upshift or downshift to either paddle, enable or disable Shimano Synchronized Shift, set multi-shift behaviour, or configure the switch as a suspension remote. The system also delivers automatic firmware updates and diagnostic reporting on startup.

Synchro Shift

When used with XTR Di2 front and rear derailleurs, the SW-M9050-R can operate in Synchronized Shift mode — a single lever input triggers coordinated front and rear gear changes, keeping you on the optimal chainring and cog combination automatically. Manual override remains available at any time.

Compatibility & Fit

The SW-M9050-R is designed for the Shimano XTR Di2 M9050 electronic groupset and is compatible with any Shimano Di2 system (mountain, road, or gravel) via the E-TUBE network. Connects via a single SD50 port. Lever position is adjustable along the handlebar axis to suit individual preference. Compatible with 10/11-speed Di2 configurations.
