Surly track cogs are designed to spin onto standard ISO-threaded (1.375" x 24tpi) hubs, so they will work with most English, Italian and Japanese hubs, including the Surly New track hubs. 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. Track cogs are available in either 3/32" or 1/8" tooth thicknesses and in every size from 13-22t.
