# Surly Track Cog 1/8'' X 15t Silver

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 hubs but this application is not recommended. Track cogs are meant to work on track hubs only.-   415 hardened chromoly steel
