Bring wireless Di2 electronic shifting to your trail build without breaking the bank. The Shimano Deore SW-M6250 right shift switch pairs precise, lightning-quick gear changes with the ergonomic I-SPEC EV direct-mount interface, keeping your handlebar setup clean and your focus on the trail. Built for 12-speed mountain Di2 systems, it delivers the same shift-on-demand performance found in higher-tier Shimano groupsets at a more accessible price point.

Highlights

  • Wireless Di2 shifting: Instant, cable-free gear changes with Shimano's proven electronic Di2 system — no cable routing, no friction.
  • Short stroke tactile paddles: A satisfying, positive click with each shift confirms every gear change and prevents accidental inputs.
  • Single click or hold-down multi-shift: Choose between precise one-click shifting or hold the paddle to sweep through multiple gears quickly on steep terrain.
  • Programmable third button: Assign functions such as trim adjust, auto-shift mode, or D-FLY input via the E-TUBE PROJECT app.
  • I-SPEC EV direct mount: Integrates neatly onto compatible Shimano brake levers — no separate clamp band cluttering the bar.
  • Multi-axis lever adjustment: Fine-tune reach and angle for a truly custom fit at the bar.
  • Long battery life: Powered by two CR1632 coin-cell batteries (included), rated for up to two years of typical use.

Design & Ergonomics

The SW-M6250 uses a rubber traction pad for a secure, comfortable grip interface against your brake lever body. The aluminium construction keeps weight low while providing durability on the trail. Lever position is adjustable on multiple axes so you can dial in the exact reach and angle that suits your hand size and riding style.

E-TUBE PROJECT Integration

Connect the SW-M6250 to Shimano's E-TUBE PROJECT app (iOS & Android) via the wireless Di2 network to customise shifting modes, assign the third button, and monitor system status. The switch communicates wirelessly with compatible Shimano Deore Di2 rear derailleurs as part of a fully wireless mountain Di2 drivetrain.

Compatibility & Fit

Designed for 12-speed Shimano mountain Di2 systems. Mounts directly to I-SPEC EV compatible brake levers — no handlebar clamp required when used in this configuration (a clamp band is also included for standard bar mounting). Compatible with Shimano Deore Di2 and other Shimano mountain Di2 groupsets. Right-hand side only (rear derailleur control). Verify I-SPEC EV compatibility with your brake lever before purchase.
