The Sunrace CSMX80 EA5 11 Speed Wide Range 11-50t cassette is built with light weight alloy cog carriers, hard wearing chromoly cassette cogs and an all alloy 50t to keep the weight down and drivetrain stiffness up.
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.
