Description

The all-new rear derailleur SHIMANO Deore Di2 M6250-SGS 12-speed long cage pushes the boundaries of MTB performance. Designed to tackle the most demanding terrain, it pairs perfectly with a standard M6200 10-51T cassette, offering an extended gear range of 500%, ideal for steep climbs as well as technical descents. Thanks to wireless Di2 technology, gear shifts are ultra-fast, precise and silent.

Its robust design is based on a wide-link structure, a durable steel plate and reinforced pulleys, guaranteeing longevity and reliability, even on the most demanding trails. The new cage shape helps deflect impacts, while preserving drivetrain smoothness thanks to covered pulleys that prevent debris ingress.

An automatic impact recovery function allows the derailleur to instantly return to its original position after a collision, ensuring continuous performance in the heat of the action. This innovative system protects the mechanism and minimises unexpected stops during a ride.

Finally, the secure battery integrated in a closed compartment stays perfectly in place, even on very rough terrain, while being easy to remove for charging.
