SunRace MX9 11 Speed Cassette

The SunRace MX9 is a high-performance 11 speed cassette designed exclusively for SRAM XD freehub bodies, a rare specification that is extremely hard to find in the market. Most XD-compatible cassettes jump straight to 12 speed, making this MX9 the perfect solution for riders who want to keep their proven 11 speed drivetrain while upgrading to XD compatibility. It delivers crisp, precise shifting with a wide 10-42T range, ideal for everything from steep technical climbs to fast, flowing descents. Built on a lightweight alloy spider with CNC-machined hi-tensile steel sprockets, it offers exceptional durability without adding unnecessary weight. For mountain, gravel, and adventure riders seeking an uncommon combination of XD fitment and 11 speed simplicity, the MX9 stands out as a unique and dependable choice.
