XTR CS-M9200 12 Speed 9-45T Cassette

What Our Gearhead® Experts Are Saying:

"This is one of the few cassettes where shifting quality actually improves when you’re riding hard. The material mix keeps weight down without sacrificing lifespan, and the shifting ramps feel incredibly refined compared to older designs."

When drivetrain efficiency is non-negotiable, we rely on components that perform consistently at the highest output levels. The XTR HYPERGLIDE+ 12-speed Cassette is engineered for riders who demand uninterrupted power delivery and precise gear changes in rapidly changing terrain. Whether racing cross-country or tackling sustained technical climbs, it maintains smooth engagement without forcing us to ease off the pedals.

HYPERGLIDE+ technology reshapes cassette tooth profiles to synchronize shifting under load, allowing continuous pedaling during upshifts and downshifts. The 9–45T cassette supports compact drivetrains. A carefully optimized material layout uses steel cogs for wear resistance, titanium cogs for weight reduction, and an aluminum carrier to maintain structural rigidity while keeping overall mass low.

MICRO SPLINE compatibility enables the use of a smaller top gear, improving cadence efficiency and drivetrain responsiveness. Designed for use with 12-speed HG chains, the XTR HYPERGLIDE+ Cassette is best suited for riders focused on competitive XC, marathon racing, and high-performance trail riding where shifting reliability and efficiency directly impact results.
