The Custom Fitted Race Number Holder is designed to fit snugly around the rear of a seat post or ISP (Integrated Seat Post). It is specifically fabricated to add extra clamping power via an integrated hidden set screw. The added security keeps the paper number from rotating in the wind as well as protecting the holder from moving up or down during a ride. The rider's number attaches via screw and nut. This product is a great addition for professional track cyclists looking for an edge with their race number holder. All of our 3d printed parts are made in our Tennessee, USA manufacturing facility.
