Bikes have changed... and so have racks! We threw the '80s blueprint (that everyone else still copies) out the window and designed a rack that solves the heel-clearance and compatibility issues that come up.
Teravail 700x28-35 inner tube with a 60mm Presta valve, built for reliability and compatibility with endurance road and gravel tires. Ideal for setups with deeper rims that need a longer valve stem.
