The SunRace CSMX8 11 Speed Cassette is a high quality, 11-Speed Wide-Ratio Cassette. SunRace originated in Taiwan in 1972, initially providing entry-level products particularly to North and South America. The boom in sales of mountain bikes resulted in rapid expansion. Twenty-five years later, it had become clear that further growth would only result from higher level components and so commenced the process of taking the product range up-market.Raleigh UK are the leading SunRace distributor in the UK holding significant stocks alongside good pricing to satisfy their customers.SunRace CSMX8 11 Speed Cassette Features11 SpeedAvailable in Black or SilverSteel SprocketsAlloy spiderRed anodized lockringWeight: 412 grams
