American Classic TUBELESS VALVES

We are taking tubeless valves to the next level. Bill Shook designed the aluminum presta tubeless valves with a revolutionary fat o-ring to contour the rim surface for an air tight seal. The valve core is removable installing sealant. The smooth inner valve surface and wide bell shaped base make sealant easy to insert into the tire without clogging. Hand tighten the valves in place. 36mm long, red anodized color, packed in pairs. When you see a red valve, you know it’s AC.

 “We discovered that the American Classic valve stems may be the best available, so buy a pair anyway and you'll be happy you did.” Richard Cunningham, Pinkbike.com
