Product details:
The XTR CS-M980 is a 10-speed Dyna-Sys cassette built for smooth, efficient, and reliable performance on the trail. Combining stiffness with lightweight durability, the cassette delivers an exceptional shifting performance in an innovative lightweight package, that can handle the rigors up uphill climbs. Shimano has been making mountain bike drivetrains for more than three decades, including eight generations of Shimano Deore XT — the original off-road drivetrain, and six generations of its flagship XTR group. Each generation is a reflection of the riding that defines the sport and the technology that defines the era.
