SHIMANO XTR RD-M9250-GS｜Wireless Di2 Rear Derailleur Forged for Racing
More than just speed. XTR truly shines on challenging trails.
The RD-M9250-GS from the XTR M9250 series is SHIMANO's newly introduced full wireless Di2 rear derailleur. Combining lightweight design with high durability, it delivers top-tier performance across a wide range of racing scenarios, from cross-country to enduro.
The mid-cage specification, optimized for 9-45T cassettes, achieves light shift response and excellent ground clearance. Paired with HYPERGLIDE+, it enables quick and precise shifting even under heavy load.
Furthermore, it features the newly developed "Automatic Impact Recovery." When encountering an obstacle, the derailleur absorbs the impact and automatically returns to its original position, significantly reducing the risk of trouble on the trail.
