The SunRace CSMZ91X WT5 10-50t 12 Speed Cassette provides a massive gear range for 1 x 12 drivetrains. Built with light weight alloy cog carriers, hard wearing chromoly 10-36t cassette cogs and AL7075-T6 42t and 50t cogs to keep the weight down and drivetrain stiffness up.
The inclusion of a 10t cog means a great gear range for flat terrain while leaving the climbing gear ratios unaltered.
Compatible with all SRAM® XD® Driver 12 speed drivetrains.
By creating a complete XD compatible 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.
