Zinger

The first kit to convert SRAM XD driver-equipped wheels for singlespeed use! We have a disproportionately large percentage of singlespeed enthusiasts in our ranks, so it’s only natural that when SRAM introduced a new freehub body in order to accommodate a larger number of gears, we started thinking about how we could convert it. The Zinger provides chainline adjustability and a broad range of cog sizes for whatever type of bike you’re lookin’ to simplify.

The first (that we know of) conversion kit to convert SRAM XD driver-equipped wheels for singlespeed use. Pair with Problem Solvers 6-bolt cogs for custom tooth counts.

  • Fits most XD driver-compatible freehubs; not compatible with SRAM ROAM series hubs
  • Fits XDR drivers when used with an appropriate cassette spacer
  • Spacers included to customize chainline
  • Includes 18t and 20t cogs
