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.
