The SunRace CSMX9X 11 Speed XD Driver Cassette is built for a XD driver freehub body using a special supplied adapter. 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 CSMX9X 11 Speed XD Driver Cassette FeaturesFor XD driver freehub10 tooth sprocket11 speedBlackAlloy spiderAlloy lockring and spacersUses supplied adapter
