Deore XT RD-M8260-SGS 11-speed Ebike Rear Derailleur - Di2, with TL-EW300

The Shimano Deore XT RD-M8260-SGS is an 11-speed Di2 e-bike rear derailleur built for modern eMTB drivetrains, pairing fast, consistent electronic shifting with the durability needed for high-torque riding and rough trails. Designed around HYPERGLIDE+ shifting performance and e-bike integration, it draws power directly from the bike’s main battery for a stable shift supply without managing a separate derailleur battery.

What matters on-trail with this Di2 e-bike derailleur

1. Direct-wired power from the e-bike battery - Eliminates derailleur battery management while maintaining consistent shifting performance on long rides.
2. E-MTB durability features - A wide link structure, skid-plate design, durable aluminum plate, and solid pulley construction help the derailleur withstand impacts, vibration, and sustained e-bike load.
3. AUTO SHIFT sensor integration - Supports intelligent shifting behavior to keep cadence and momentum more consistent on changing grades (when paired with a compatible e-bike system setup).
4. FREE SHIFT technology - Allows shifting while coasting, so riders can set up the next gear before re-engaging the pedals on flats, downhills, or into corners.
5. SHADOW ES chain management - A slimmer, stronger evolution of Shimano’s chain-stabilizing design concept to help reduce chain movement and improve drivetrain security in rough terrain.

Includes TL-EW300 service tool for working with EW300 E-Tube connections.
