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

Sometimes less is more. With the 10-speeds, an 11-48T range, and evenly spaced gear steps, the ADVENT X cassette allows riders to shift less often to find the right gear, while still having enough range to ride what they want.

In short, it's everything you want in a high-end drivetrain. - Two alloy large cogs and a full alloy spider eliminate unwanted weight - Ramped cogs aid in shifting under load - Continuously molded construction maintains straightness and durability - Compatible with standard HG freehub bodies and 10-speed chains - Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed - Cassette Cogs: 11-13-15-18-21-24-28-34-40-48
