Shimano Deore Di2 RD-M6250 Wireless 12-Speed Rear Derailleur – HYPERGLIDE+, SGS Long Cage (Without Battery)
Experience next-generation shifting precision with the Shimano Deore Di2 RD-M6250 Wireless 12-Speed Rear Derailleur (HYPERGLIDE+, SGS Long Cage), engineered for ultimate performance, durability, and control across all mountain and e-MTB terrains.
This 12-speed Shadow ES rear derailleur delivers precise, reliable wireless shifting using BLE and ANT private connectivity, ensuring smooth, instant gear changes every time. Designed for HYPERGLIDE+ 12-speed drivetrains, the Deore Di2 RD-M6250 combines advanced electronic integration with rugged construction for consistent performance in any conditions.
The derailleur features an integrated removable battery system (BT-DN320 sold separately) housed securely within the linkage for enhanced protection and durability. Its crash recovery function automatically absorbs impact and returns to position, maintaining drivetrain alignment after hard hits.
Built with Shimano Shadow ES technology, the RD-M6250 boasts a super low-profile design and dual-spring chain stabilizing system, significantly reducing chain bounce and maintaining stable, silent shifting on rough terrain. The 70% increased spring force ensures tighter chain wrap, improved gear engagement, and reduced skipping, even as components wear.
The 13T solid pulleys, steel pulley cage, and cold-forged alloy links provide outstanding strength and reliability, while fluorine-coated link bushings minimize friction for long-lasting, smooth performance.
