The Deore Di2 RD-M6250 12-speed rear derailleur combines Shimano’s proven Di2 electronic shifting with a robust, trail-ready design—giving riders precise, ultra-fast wireless shifting in a durable package built to withstand aggressive riding. Its long-cage design is optimized for 10-51T cassettes, while the integrated battery, Automatic Impact Recovery, and shielded construction ensure consistent performance no matter the terrain.

• Trail-Ready Durability: Wide link structure, impact-deflecting wedge shape, and solid pulley provide enhanced resistance to trail impacts and wear.
• Automatic Impact Recovery: Derailleur automatically returns to position after impact, maintaining smooth performance on rough terrain.
• SHIMANO SHADOW ES Technology: Evolved chain stabilization with a lower profile for better clearance and fewer snags.
• 12-Speed Wireless Precision: Clean, fast, and consistent shifting with a full 500% gear range.
• Integrated Battery Design: On-board battery is securely enclosed for protection, yet easy to remove for charging.
• Debris-Blocking Construction: Covered pulley teeth and cage design prevent dirt and trail debris from compromising function.
