The SunRace CSMZ90 WA5 12 Speed Cassette provides a massive gear range for 1 x 12 drivetrains. Built with light weight alloy cog carriers, hard wearing chromoly 11-38t cassette cogs and AL7075-T6 42t and 50t cogs to keep the weight down and drivetrain stiffness up.
Compatible with standard cassette bodies, no special cassette body needed. Compatible with all 12 speed drivetrains.
By creating a complete cassette we have been able to optimize the cassette ratios for the smoothest and most efficient transition between gears.
Each jump through the gears is designed to keep your leg speed stable and efficient, maximizing every watt of energy.
