SHIMANO DEORE Di2 RD-M6250 12-SPEED REAR DERAILLEUR

The Shimano RD-M6250 DI2 Wireless DEORE 12-speed rear derailleur combines cutting-edge wireless shifting technology with legendary durability.

Featuring automatic impact recovery that instantly restores the derailleur to its original position after crashes, this long-cage mech is built to withstand demanding terrain. The innovative dual-spring Shadow ES design reduces chain bounce and increases spring force by 70%, preventing skips even as cassette teeth wear. With 13T solid pulleys, fluorine-coated bushings, and compatibility with 10-51T SGS cassettes, it delivers reliable performance on every ride. Battery sold separately.

Features

• SGS long cage for 10-51 cassette: Speed paired with range; the long cage rear derailleur withstands hard impacts on the trail and scores with lightning-fast shifting speed and top-class performance at the same time
• Robust Design: A wide link structure, skid-plate design, durable steel plate and solid pulley add robustness and longevity
• RD Protection Function: A new automatic impact recovery function instantly returns the derailleur motor to its original position after impact
