Like all surly cassette and track cogs, these are made from machined, heat-treated and chrome plated SCM415 CroMoly steel, so they are tough and long lasting. They're available in 3/32" (narrow chain) tooth width 17/19t or 17/20t combinations. We recommend using 9-speed chains only. You can thread it onto any standard ISO threaded (1.375x24tpi) fixed gear hub and it takes up the same 7.4mm threads as a standard fixie cog. We recommend using a wider lockring (like our improved track lockring) to assure you can get a lockring tool onto it.

The thread base is 7.4mm wide for maximum thread engagement while maintaining enough room for a track lockring to thread on. Like Surly cassette-splined cogs, these are made from machined, heat-treated and chrome plated SCM415 CroMoly steel, so they are tough and long lasting.
