Origin8 Freehub Kit

This kit is compatible with any standard Shimano or SRAM-style cassette body. If your hub currently accepts a standard multi-speed cassette from those brands, this conversion kit will fit.

The varying spacer sizes are essential for dialing in your chain line. By mixing and matching these spacers, you can precisely position your single cog to align perfectly with your chainring, which reduces drivetrain wear and prevents the chain from dropping.

The conical shape helps the spacers seat more securely against the cog. This design increases overall stiffness, which translates to more direct power transfer when you pedal hard, rather than the cog flexing or shifting under load.

No, this kit includes the spacers necessary to position your cog, but it does not include the single-speed cog itself or the lockring. You will need to source a single-speed cog and a lockring separately to complete your conversion.

Yes, 6061 alloy is a standard, reliable material for this application. It offers an excellent balance of strength and low weight, making it more than capable of handling the torque and stress of daily single-speed riding.
