Take your mountain biking performance to the next level with the Shimano XTR M9250 Di2 12-Speed Upgrade Kit, featuring the long cage rear derailleur and wireless shifter. Engineered for elite-level performance on the most demanding trails, this system offers lightning-fast, precise shifting combined with rugged impact resistance and a streamlined, durable design. Whether you're racing enduro or tackling technical descents, the XTR M9250 is built to perform and endure.
Robust Design and Impact Resistance
The XTR M9250 rear derailleur is built with a wide link structure, a protective skid plate, and a strong carbon outer cage, ensuring maximum strength and longevity on rough terrain. The new wedge-shaped body is designed to deflect hits and glance off obstacles, reducing the likelihood of direct damage in technical conditions.
Automatic Impact Recovery and SHIMANO SHADOW ES
This derailleur features Shimano’s new Automatic Impact Recovery system, which allows the derailleur to instantly return to its original position after impact, preserving shifting performance mid-ride. Meanwhile, the SHIMANO SHADOW ES design offers a slimmer, more protected derailleur profile, reducing snag risk and improving chain stability across the gear range.
Wireless Shifting with HYPERGLIDE+
Shifting is faster, cleaner, and more intuitive than ever thanks to Shimano’s wireless Di2 system. Combined with HYPERGLIDE+ cassette technology, gear transitions are seamless and precise even under heavy pedaling load. The integration ensures immediate responsiveness whether climbing steep switchbacks or sprinting on flats.
Protected, Removable Battery System
The system’s battery is securely housed inside a protected enclosure to keep it safe from trail abuse. Despite its robust location, the battery remains removable for easy off-bike charging, offering both convenience and peace of mind for long rides and race days.
