Phil Wood manufactures their track chainrings from US-produced 7075 billet aluminum, which is put through special processes that maximize hardness and minimize internal material stresses.

Each chainring is made from start-to-finish at Phil Wood's facility in San Jose, CA to the same extremely high quality standards Phil Wood and Co. applies to all of their products.
