Phil Wood’s stainless steel track cogs, available in 1/8″ and 3/32″ widths, from 15 to 22 teeth.
The cog threading is 1.370″ x 24 tpi. The cogs are manufactured from solid stainless steel bars and are heat-treated three separate times. In order to show that the cog is not plated, it is polished and laser etched on the outer face while leaving the inside face in its “natural” state.
These track cogs are great for use with Phil track hubs, as they are machined to work together seamlessly.
Other track cogs on the market often have varied widths, sometimes resulting in a cog that is too wide for the threads on Phil track hubs which can lead to less than complete engagement of the lock ring and thread stripping from the hub.
