Engineered for elite mountain biking performance, the Shimano CS-M9200 XTR 12-Speed 9–45T cassette offers class-leading technology and an innovative gear range to meet the demands of XC racers, trail riders, and enduro competitors. With its compact design and premium materials, this cassette strikes the perfect balance between durability, precision, and reduced weight—making it a must-have for riders chasing every gram and every second.
Lightweight and High-Strength Construction
The CS-M9200 features a sophisticated 5-beam alloy spider carrier supporting a mix of 3 alloy, 5 titanium, and 4 chromoly sprockets. This combination delivers exceptional stiffness while keeping weight to a minimum. Extensive cut-outs and weight-reducing drills maintain rigidity while shedding unnecessary grams—ideal for competition-focused builds.
Hyperglide+ Performance Under Load
This cassette is equipped with Shimano’s advanced Hyperglide+ technology, offering seamless shifting under load both up and down the cassette. The computer-designed tooth profiles and ramping improve chain engagement, reduce shift shock, and allow smoother transitions—critical when climbing, sprinting, or riding technical terrain.
Optimised Compact Gear Range
With a 9–45T spread, this cassette provides a wide yet compact range designed to offer optimal ground clearance for aggressive trail and enduro riding. The smaller 9T sprocket also reduces overall drivetrain size and weight, benefiting cross-country racers who demand maximum efficiency without sacrificing performance.
Micro Spline Compatibility and Longevity
This cassette is compatible exclusively with Shimano’s Micro Spline freehub body, ensuring a secure fit and high-performance interface. A hard-anodised and nickel-plated finish adds corrosion resistance and extends wear life, even in harsh riding conditions. This cassette is intended for use with Shimano 12-speed chains and includes a specific lockring for the 9T top gear.
