Shimano XTR M9250 Di2 Upgrade Kit

The M9250 kit is designed to work with Shimano 12-speed mountain bike drivetrains. However, you should ensure your current crankset and chainring are compatible with Shimano Hyperglide+ chains for optimal performance.

While the shifting signal between the shifter and the derailleur is wireless, the system still requires a wired connection between the rear derailleur and the internal battery. This ensures a stable power supply and reliable communication throughout the frame.

Battery life depends on usage, but most riders can expect several hundred miles of riding on a single charge. The system includes an LED indicator on the derailleur that alerts you when the battery level drops below 20%.

Yes, this kit is specifically designed to convert mechanical setups to electronic. You will need to remove your existing shifter cable and housing, and ensure your frame has space to house the internal battery, typically within the seat post or down tube.

If the battery is fully depleted, the derailleur will stop shifting and remain in its last gear. It is good practice to check your battery status via the Shimano E-TUBE PROJECT app before heading out on long rides.

Initial setup and customization, such as adjusting shift speed or button assignment, are managed through the Shimano E-TUBE PROJECT app via Bluetooth. While you can perform basic installation without it, the app is essential for fine-tuning the system to your preferences.
