Phil Wood ISO Track Cog 345-130

Phil Wood's stainless steel ISO bolt pattern cogs are manufactured in 1/8" widths. The bolt pattern and screw size are same as that used in the disc brake hubs.

Phil's track cogs are manufactured from solid stainless steel bars and are heat-treated three separate times. In order to show that their cog is not plated, they polish and laser etch the outer face of each cog while leaving the inside face in its natural state.
