The Zinger is the first kit to convert SRAM XD driver-equipped wheels for singlespeed use! There is a large percentage of singlespeed enthusiasts out there, so it's only natural that when SRAM introduced a new freehub body in order to accommodate a larger number of gears, Problem Solvers got started thinking about how they could convert it. The Zinger provides chainline adjustability and a broad range of cog sizes for whatever type of bike you're looking to simplify.
