Cassette Sprocket Shimano XTR CS-M9100 10-51T 12s

Built with an increased gear ratio, the XTR M9100 12-speed cassette is 30% stiffer than previous models and maintains a lower weight to maximize efficiency when making those vital shifts. Equipped with a 10-51 tooth system, the cadence jumps when moving between gears are kept low to maintain high speeds and a consistent pace as you progress through your run. With Hyperglide + technology, the cassette benefits from small shift ramps that lead the chain to the next sprocket when going up through gears and down, preventing the chain from dismantling. This ensures a consistent gear change at all times without impact on your cadence. A fantastic set of sprockets for the thrill-seeking trail and downhill rider, the XTR M9100 12-speed cassette is more than equipped for the boldest rides.
