The thread base is 7.4mm wide for maximum thread engagement while maintaining enough room for a track lockring to thread on. Like our cassette-splined cogs, these are made from machined, heat treated and chrome plated SCM415 CroMoly steel, so they are tough and long lasting.
Track cogs are available in either 3/32" or 1/8" tooth thicknesses and in every size from 13T - 22T
