Shimano XTR CS-M9100 Sprocket

No, this specific unit is designed exclusively for the Shimano XTR CS-M9100 12-speed cassette. It is engineered to meet the exact tolerances of that specific model, so it should not be used with other cassette series.

Yes, this kit includes the 10T and 12T sprockets, the necessary spacer, and the lock ring. It provides all the essential components required to secure the end of your CS-M9100 cassette.

Using genuine Shimano parts ensures that the material hardness, tooth profile, and spacing match the rest of your drivetrain exactly. This precision is critical for maintaining the crisp, reliable shifting performance that the XTR system is known for.

If you have a cassette lockring tool and a chain whip, you can perform this installation yourself. However, because this is a high-performance drivetrain component, ensure you torque the lock ring to the manufacturer's specified setting to prevent movement or damage.

These sprockets are constructed from high-quality steel. This material choice balances durability with the lightweight performance requirements of the XTR line.
