SunRace SPCS12 X is a replacement sprocket unit for 12-speed MTB cassettes, featuring durable steel 10T, 12T and 14T sprockets with a lightweight aluminium lockring.
Cassette spare parts allow you to service and restore your drivetrain without replacing the entire cassette. Individual cassette sprockets as spare parts are a practical solution when only one or a few worn sprockets need replacement.
Replacing worn sprockets helps maintain smooth shifting, extends the lifespan of the cassette and chain, and reduces overall maintenance costs. These spare parts are suitable for different gear counts and drivetrain systems, for both performance and everyday riding.
Our range includes high-quality cassette spare parts and sprockets designed for precise repairs and reliable long-term drivetrain performance.
