SunRace CSRX1 11-Speed Cassette Silver 11-25T, 11-28T

From SunRace, the RX1 11-Speed Cassette is designed to deliver smooth shifting across all sprockets, making it a considered choice for riders looking for a fast, reliable setup. Finished in silver, it pairs hi-tensile steel sprockets with a Ti-Ni coating for a durable, hard-wearing build suited to regular road use.

Details such as the alloy spider, lightweight holes, and an aluminium spacer and lock ring help keep the design focused and efficient, while remaining compatible for completing a Shimano or SRAM drivetrain. Offered in 11-25T and 11-28T options, it’s a practical upgrade for refining gear changes and maintaining consistent performance over time.
