The SunRace CSMX80 pairs high-strength steel sprockets for the most-used ratios with 7075 aluminium sprockets for the two largest cogs (42T and 50T). This combination optimises durability while reducing weight thanks to the red anodised spiders.
With a tooth distribution of 11-13-15-18-21-24-28-32-36-42-50, the cassette provides a very wide gear range suitable for demanding terrain and steep climbs, making pedalling easier in all situations.
Compatible with standard HG freehub bodies and SRAM/Shimano 11-speed drivetrains. Some Shimano derailleurs may require a longer B-tension screw to accommodate the 50-tooth sprocket; using a long-cage derailleur is recommended.
Total weight of approximately 512 g, achieved by the strategic use of lightweight yet strong materials. Silver finish with red anodised spiders for a refined look that fits well on an All-Mountain MTB.
