Cassettes/Freewheels
Cassettes amd freewheels are the back part of the drivetrain. They come in a variety of gears (number of cogs) and ranges (to make pedalling harder or easier) and are different in the way they connect to the wheel. We carry a good selection, and also the tools to remove them.

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. Fewer cogs also means less weight and a wider chain for better mud shedding. It even fits on standard 10-speed freehub bodies so you don't need to buy new wheels for no reason. In short, it's everything you want in a high-end drivetrain.
