The Shimano XTR RD-M9260 is Shimano's flagship rear derailleur engineered exclusively for high-performance E-MTB — combining wireless Di2 electronic precision with LINKGLIDE drivetrain durability and intelligent auto-shifting features built for the demands of e-mountain riding.

Highlights

• Wireless Di2 shifting: Fast, precise electronic shifting powered directly from the e-bike's main battery — no separate Di2 battery to manage.
• LINKGLIDE compatibility: Wide-profile chain engagement and stepped cassette flanks deliver dramatically longer drivetrain service life under high-torque e-bike loads.
• AUTO SHIFT: Automatically selects the optimal gear while you pedal so you can stay focused on the trail ahead.
• FREE SHIFT: Continues shifting even when you're coasting or off the pedals, so the next pedal stroke always lands in the right gear.
• SHIMANO SHADOW ES chain stabilisation: Low-profile, high-force clutch mechanism delivers confident chain retention on rough and technical terrain.
• Automatic Impact Recovery: Motor instantly repositions the derailleur after a rock strike or impact — no manual reset required.
• Long cage (SGS): Handles cassette ranges up to 11–50T with a total capacity of 39T.
• 13T solid sealed-bearing pulleys: Debris-resistant pulley wheels for reliable performance in muddy and abrasive conditions.
• Carbon outer cage: Full carbon fibre outer plate with alloy inner cage for excellent stiffness-to-weight ratio.
• Wide linkage structure: Cold-forged alloy links and pivot body with fluorine-coated bushings for long-term smoothness.

LINKGLIDE and Di2 for E-MTB

E-MTBs place unique demands on a drivetrain — higher torque loads, frequent shifts under power, and rough terrain that punishes components. The RD-M9260 pairs LINKGLIDE technology (wider chain-tooth profile, stepped cassette flanks) with wireless Di2 electronics to deliver shift engagement that resists wear far longer than standard HG systems. Every shift is fast and consistent regardless of trail conditions or motor assist level.

Intelligent Shifting Features

AUTO SHIFT monitors riding dynamics and automatically selects the optimal gear while pedalling, letting you focus entirely on the trail. FREE SHIFT allows the system to continue shifting even when you're coasting through a corner or rolling into a descent — so the next pedal stroke always finds the right gear without any manual input. Both features operate through the SHIMANO STEPS integration, drawing power from the e-bike's main battery for stable, uninterrupted shifts.

Built for Trail Survival

The wedge-shaped body deflects rock strikes, while the low-profile skid plate protects against direct impacts. SHADOW ES provides significantly increased spring force over previous-generation stabilisers for superior chain retention on aggressive terrain. When impacts do occur, Automatic Impact Recovery instantly repositions the derailleur motor to restore normal shifting — keeping you moving without manual adjustment.

Compatibility & Fit

Designed exclusively for E-MTB use with a SHIMANO STEPS e-bike system. Requires EW-SD300 wired Di2 connection to the main e-bike battery. Compatible with 11-speed LINKGLIDE cassettes and chains (CN-LG500 or CN-E8000 recommended). Cassette range: 11T minimum high sprocket, 50T maximum low sprocket, 39T total capacity. Long cage (SGS). Compatible with XTR M9200 Di2 E-MTB groupset. Not compatible with standard (non-STEPS) Di2 setups or mechanical drivetrains.
