The Shimano XTR RD-M9260 is the flagship electronic rear derailleur engineered specifically for electric mountain bikes, delivering wireless Di2 precision powered directly by your e-bike's battery — no backup battery required. Built to XTR's uncompromising standard of durability and intelligence, it handles the extra torque and sustained load of E-MTB riding while keeping you in the optimal gear on every climb and descent.

Highlights

• Wireless Di2 shifting: electronic precision powered from the e-bike's main battery — no separate battery pack needed.
• 12-speed HYPERGLIDE+: compatible with 51T maximum sprocket for a wide gear range suited to E-MTB terrain.
• AUTO SHIFT E-Bike technology: automatically selects the optimal gear while pedalling, keeping power delivery consistent on climbs.
• FREE SHIFT E-Bike technology: shifts automatically as you coast or descend, so you're always in the right gear for the next effort.
• SHIMANO SHADOW ES clutch: slimmer, stronger chain stabilisation with reduced noise and resistance to trail snags.
• Automatic Impact Recovery: instantly repositions the derailleur after a strike without interrupting your ride.
• Long-cage (SGS) design: optimally paired with the CS-M9200 10–51T cassette for full range and smooth transitions.
• Robust E-MTB construction: wide link structure, skid-plate, carbon plate, and solid pulley assembly built for high-torque durability.

Built for E-MTB Demands

E-MTB riding places exceptional demands on drivetrain components — higher torque, sustained loads, and frequent shifting at speed. The RD-M9260 addresses this with a wide link structure, skid-plate design, durable carbon plate, and a solid pulley assembly, all combining to deliver longevity where ordinary derailleurs wear prematurely. The slim stabiliser design keeps the system quiet on rough terrain without sacrificing chain retention.

Intelligent Shifting Technology

AUTO SHIFT uses intelligent sensors and HYPERGLIDE+ to deliver smooth, rapid gear changes under pedalling load. FREE SHIFT handles transitions as you coast: the system automatically moves into an appropriate gear so you're ready for the next effort the moment you put power down again. Both technologies integrate seamlessly with Shimano's STEPS E-MTB ecosystem for a cohesive riding experience.

SHADOW ES Chain Stabilisation

The SHADOW ES clutch system is Shimano's most advanced chain management solution. Its slimmer, lower-profile design reduces front-facing surface area to avoid trail snags, while the dual-spring chain-stabilising mechanism keeps tension and retention high on rough ground. Combined with Automatic Impact Recovery, the RD-M9260 maintains reliable shifting through the most technical terrain.

Compatibility & Fit

The RD-M9260 is designed for 12-speed Shimano HYPERGLIDE+ drivetrains and is optimally paired with the Shimano CS-M9200 10–51T cassette. It connects directly to the e-bike's main battery for power — a wired connection to the battery is required; shifting communication is wireless Di2. This is an E-MTB-specific derailleur and is not intended for non-motorised bikes. Confirm compatibility with your frame and groupset before purchasing, or contact Tune Cycles for advice.
