The Trail One Tubeless Valve Stem V2

Version 2 of our best-selling tubeless valve improves on our previous design with even better clearance for tire inserts, more colors and a more stealthy valve core tool built into each cap.

Most new bikes still come fitted with tubes even though they are sold with tubeless ready tires and wheels -- it's a bit of a mess to do it at the factory. 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.

We are on a mission to make phenomenal products that support the sport of mountain biking. For every Trail One Valve Stem kit 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.
