Deore RD-M6250-SGS Di2 Wireless Rear Derailleur - 12-Speed, Long Cage, Shadow ES

The Shimano Deore RD-M6250-SGS Di2 Wireless Rear Derailleur delivers the precision and reliability mountain riders demand, now in a more accessible 12-speed Di2 package. Designed for serious trail performance, this long-cage derailleur pairs perfectly with a 10-51t cassette to offer a wide gear range and smooth, consistent shifting on everything from steep climbs to fast descents.

Built to take a beating, the RD-M6250 combines an impact-deflecting wedge shape, reinforced steel and aluminum construction, and Automatic Impact Recovery—so when the trail gets rough, it automatically resets itself to perfect alignment. Riders can count on the same crisp, wireless Di2 shifting that has made Shimano’s electronic drivetrains legendary, without worrying about trail damage slowing them down.

The integrated, removable battery is tucked safely within the linkage, protected from impacts yet easy to remove for charging. Plus, Shadow ES technology refines the chain-stabilizing design Shimano pioneered, keeping the drivetrain slim, quiet, and secure no matter how rowdy the ride gets.

• 12-speed Di2 wireless shifting for lightning-fast, precise gear changes.
• Automatic Impact Recovery resets derailleur position instantly after a hit.
• Shadow ES design keeps the profile low and the chain stable on rough terrain.
• Durable wide-link structure and skid-plate protection for long-lasting trail toughness.
• Protected, removable battery integrates seamlessly and connects with cycling computers.

Rugged, smart, and built for riders who push their bikes as hard as they push themselves, the Shimano Deore RD-M6250-SGS Di2 brings elite electronic shifting to everyday trail adventures.
