So the first order of business on New Bike Day is to pull out the tubes, grab a set of Trail One Tubeless Valve Stems, toss in some sealant, and pump away to tubeless perfection. And if it's not New Bike Day then it's probably time to swap out whatever gummed up old valve stems you've got for something fresh. The Valves come with two metal caps, one extra cap that doubles as a valve core remover, and also an extra valve core if they get plugged up. We are on a mission to make phenomenal products that support the sport of mountain biking. For every Trail One Fender sold, we will add $1 to the Trail One Treasury. The Treasury will periodically award funds to deserving trail networks. We exist to support the trails we love, the people that take care of them and to make your riding experience exceptional.Sold as a pairIncludes 2 metal caps with built in valve core removerIncludes 1 extra valve coreItem SpecificationsKeyword searchTubelessLength (mm)40MaterialAlloyValve CoreRemovableValvePresta Trail One Components T1 Valve Stem V2 Tubeless Valves
