12-Speed Micro Spline MTB Cassette

Smooth Power. Relentless Precision.

Engineered for riders who demand seamless shifting and dependable performance, this high-performance 12-speed Micro Spline cassette delivers crisp, precise gear changes — even under heavy load. Whether you’re grinding up climbs or hammering through descents, every shift feels deliberate and controlled.

Using Hyperglide sprocket technology, each tooth is computer-designed with contoured shift gates for faster, smoother transitions across the cassette. The result? Effortless cadence control and efficient power delivery across constantly changing trail conditions.


Built for Performance

Close-ratio gearing helps you make the most of every pedal stroke, keeping cadence tight and energy use efficient. The largest sprockets are mounted on lightweight alloy carriers to boost stiffness and cut weight, while precision-cut and drilled sprockets shed extra grams without compromising rigidity.

A chrome-plated finish provides lasting resistance to wear and corrosion, and the alloy lockring keeps everything secure — ride after ride.
