Bespoke track cogs are perfectly machined from hardened stainless steel and feature the same tooth profile found on Bespoke track chainrings to ensure a smooth, reduced friction drivetrain.

Available in sizes 12t-18t with an oil slick titanium PVD coating or gold titanium nitride coating for optimum performance, durability, and beauty.

FYI: All track cogs have 1.37"x24tpi threading. ALL OF THEM. Any threaded cog can be used on any threaded track hub.
