Shimano XTR Di2 M9250 12sp Shifter

The Shimano XTR Di2 SW-M9250 12-speed shifter is the control interface that brings the unparalleled speed and precision of Shimano's flagship electronic mountain bike drivetrain to your fingertips. Designed for riders who demand ultimate control and a clean cockpit, this wireless shift switch offers advanced ergonomics, lightning-fast response, and extensive customization options for a truly personalized riding experience.

• Wireless Di2 Shifting: Communicates wirelessly with the XTR Di2 RD-M9250 rear derailleur, eliminating cables for a super clean and uncluttered handlebar setup. This also contributes to faster, more consistent shift performance without cable friction.
• RAPID ES Technology: Delivers precise, instantaneous shifts with a crisp, tactile feel. Shimano's electronic shifting ensures every command is executed with accuracy, regardless of trail conditions or hand fatigue.
• Multi-Axis Adjustability: Features an ergonomic design with extensive adjustability. Both shifter paddles can be independently positioned and rotated, allowing riders to fine-tune the shifter's placement to perfectly match their thumb's natural resting position and preferred angle, reducing hand fatigue and enhancing control.
• Customizable Shift Modes: Offers multiple shift modes to adapt to your riding style:
  • Single Click: A single press for one gear shift.
  • Double Click: Pressing further for an immediate two-gear shift.
  • Hold-Down Multi-Shift: Holding the paddle down to shift across multiple gears quickly. These modes can be enabled or disabled via the E-TUBE Project app.
• Programmable Third Button: A versatile third button on the face of the shifter can be custom-assigned via the E-TUBE Project app. This allows for control of various functions, such as:
  • Micro-adjusting derailleur trim on the fly.
  • Scrolling through screens on a connected GPS device.
  • Controlling other compatible e-bike functions or third-party integrations.
• Ergonomic Design & Rubber Traction Pad: The familiar shape combined with a textured rubber traction pad ensures secure grip and comfortable lever feel, even in wet or muddy conditions.
• Mounting Options: Available in:
  • **SW-M9250-IR (I-SPEC EV):** For seamless integration directly onto compatible Shimano I-SPEC EV brake levers, creating a unified and minimalist cockpit.
  • **SW-M9250-R (Clamp Band):** For traditional handlebar mounting, offering broad compatibility.
• E-TUBE Project Connectivity: Full wireless customization and firmware updates are available through the Shimano E-TUBE Project mobile app (via Bluetooth® LE), allowing you to personalize every aspect of your shifting experience.
• Lightweight & Durable: Constructed with high-quality materials to be both lightweight (approx. 97g for I-SPEC EV, 104g for Clamp Band) and robust enough to withstand the demands of aggressive mountain biking.
