Just three months after its official launch, SHIMANO’s flagship XTR M9200 Di2 groupset has already powered riders to victory on the world stage—proof that this fully wireless electronic system is built for performance. After extensive testing on varied terrain, we’re breaking down what makes it a game-changer.
True Full-Wireless Design
XTR Di2 marks SHIMANO’s first fully wireless electronic groupset for mountain biking. The system includes:
RAPID ES Di2 shifters – highly customizable, with adjustable paddle positions and tactile feedback close to mechanical shifting

M9250 rear derailleur – features Shadow ES technology for better protection and dual-spring chain stabilization

Coin-cell battery power – CR1632 batteries in shifters; a compact 305mAh battery in the derailleur
Shifters connect via Bluetooth to SHIMANO’s E-TUBE app, allowing personalized button configuration and connectivity with cycle computers or motors.
Braking Performance, Refined
The new XTR brake system uses low-viscosity mineral oil for consistent performance across temperatures. Key updates include:
Redesigned SERVOWAVE lever with 5° upward tilt for ergonomic grip
Tool-free reach and bite point adjustment
One-piece 4-piston caliper with resin pistons and finned brake pads
Improved consistency and power under all conditions
Seamless Compatibility & Familiar Tech
While shifting goes wireless, XTR maintains compatibility with existing 12-speed SHIMANO MTB ecosystems:
Still offers 10-51T and new lighter 9-45T cassette options with HYPERGLIDE+
HOLLOWTECH II cranks with multiple length options
Micro Spline freehub body and standard derailleur hanger
Easy upgrade path for current 12-speed SHIMANO users—no compatibility worries
