Description

The brand new rear derailleur SHIMANO XT Di2 M8250-SGS 12-speed long cage pushes the limits of MTB performance. Designed to tackle the most demanding terrain, it pairs perfectly with a standard M8200 10-51 tooth cassette, offering an extended gear range of 500%, ideal for steep climbs as well as technical descents. Thanks to wireless Di2 technology, gear changes are ultra-fast, precise and silent.

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

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

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