DESCRIPTION

A traditional clincher rim attaches the tire by lodging the tire bead under a hook in the most outer diameter of the rim. This style of clincher rim is typically referred to as a hook-bead or crochet style rim. As the tire pressure increases, the force on the outer diameter hook portion of the rim increases. At 145 psi (10 bar), the hook must retain approximately 7975 pounds of total force from the air pressure in the tire.
