Description

The SHIMANO XTR Di2 Wireless M9250-GS 12V rear derailleur represents the new benchmark in performance and robustness for high-level mountain bikers. Designed to withstand the most severe impacts, it is aimed at both professional enduro riders and cross-country competitors conscious of weight. Its compatibility with the compact 9-45 cassette and its medium cage make it an ideal solution for technical terrain.

This derailleur benefits from the very latest wireless Di2 technology, delivering ultra-fast, precise and effortless gear changes. Thanks to HYPERGLIDE+ technology and the SHIMANO SHADOW ES system, it guarantees smooth pedalling even on the most demanding trails. Its new wedge-shaped profile and an additional 23 mm of ground clearance limit the risk of direct impact with obstacles.

One of the key strengths of the M9250-GS is its automatic recovery function after impact: in the event of a shock, the derailleur motor instantly returns to its initial position, ensuring uninterrupted performance. Its reinforced structure integrates a solid cage, a carbon derailleur hanger and solid pulleys.

Finally, its protected battery, discreetly integrated, remains stable on rough terrain while being easily removable for charging.
