The Shimano Deore M6250 Shadow ES Rear Derailleur is the ultimate choice for the rider seeking a reliable, high-tech, and robust drivetrain upgrade that delivers flawless wireless shifting performance on every trail.
Wireless Shifting with Integrated Power: Experience the freedom and simplicity of wireless shifting. The system uses an integrated, removable battery (BT-DN320 sold separately) that is protected within the derailleur's linkage, ensuring a tidy setup and easy charging. It communicates via both BLE and ANT private for reliable connectivity.
Intelligent Crash Recovery: Engineered for real-world riding, the derailleur features a crash recovery function. In the event of an impact, the derailleur will absorb the force and automatically return to its original position, helping to prevent damage and keep you riding.
Advanced Shadow ES Stabilisation: The Shadow ES system features a dual-spring chain stabilising switch. When engaged, this switch significantly reduces chain bounce over rough terrain, maintaining a more stable drivetrain. This results in more secure shifting and a quieter ride. The system's unique structure provides a tighter chain wrap and a 70% increase in spring force, ensuring the chain meshes firmly with the sprockets, even as they begin to wear.
Robust, Low-Profile Design: The derailleur features a super-low-profile skid plate design and an optimised slant angle for excellent clearance over rocks and roots. The cold-forged wide alloy links and pivot body, along with a dependable steel pulley cage, provide exceptional strength and durability.
Maintenance-Free Performance: The Shadow ES system is designed for zero maintenance, with no degradation of shifting performance over time. This means you can spend less time in the workshop and more time on the bike.
Wide-Range Gearing: The derailleur's 10-51 tooth compatible SGS (long) cage is specifically designed to work with wide-range 12-speed drivetrains, providing a huge gear spread for tackling any climb or sprint.
Smooth & Efficient Operation: Featuring 13-tooth solid pulleys and decreased derailleur tension in low gears, the system prevents high chain tension and ensures soft, consistent performance across the entire cassette.
