Overview
Cassette Sprocket Shimano XT CS-M771-10 15T BJ/BK
Shimano Deore XT CS-M771-10 15T is a genuine replacement 15-tooth sprocket for Shimano XT 10-speed cassettes. Specifically designed for CS-M771-10 11-34T (BJ) and 11-36T (BK) cassette versions, it allows a worn or damaged sprocket to be replaced without changing the complete cassette.
Manufactured from durable steel, the sprocket offers excellent wear resistance and long-lasting performance. Genuine Shimano tooth profiling helps maintain smooth and precise gear shifting, even under demanding off-road conditions. This replacement sprocket is a practical solution for drivetrain maintenance and restoring original shifting performance.
Weighing just 16 grams, the sprocket is compatible with two CS-M771-10 cassette configurations. The BJ designation corresponds to the 11-34T cassette, while the BK designation identifies the 11-36T version.
