Low Price Surly Track Cog 3/32” X 16t Silver

Surly track cogs are threaded the same as a BMX freewheel (1.375 x 24 tpi righthand threads). This means that they will fit on singlespeed 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
