Surly track cogs are threaded the same as a BMX freewheel (1.375 x 24 tpi right-hand threads). This means that they will fit on single-speed rear hubs, as well as BMX freewheel hub s, but this application is not recommended. Track cogs are meant to work on track hubs only. 415 hardened chromoly steel 1.375" x 24 tpi Show more
