Problem Solvers 3/32 Inch Disc Mount Fixed Sprocket - Silver

Sprockets with 6-bolt hole pattern, just like disc rotors, so you can attach them to hubs with disc rotor mounts for fixed gear use.

Can also be used with a Cassette Cog Carrier (available seperately) which is Shimano-splined and sandwiches spline-less sprocket. This gives you a wide profile that won't damage your freehub.

6-Bolt compatible (see instructions for safety warnings).
