Tubeless Valve Stem - Super Light Alloy - Pair - Choose Color/Size

I'll admit I was hesitant to by these, but they work well. Seals tightly with no leaks. Whereas my stans valve stem failed during massive drops or when I bend the valve around with my hands, these work well, don't leak. and look good. Give them a shot.

The stems are as good as any from Stan's, American Classic, etc... but cheaper, and the support from VeloTubes is superb. I will not hesitate to order from them in the future-- and as I'm up to 5 sets of tubeless wheels now, likely sooner than later.

This valves a great and cheap too..get the job done and for the right price. Slap em in my ht added some sealant and ready to go..the runner o ring is a nice touch to prevent sealant/air from leaking...ordered another paired for my full sus..

Used these to convert my Salsa Cutthroat to tubeless. Maxxis Ikon tires, WTB ST i23 TCS 2.0 rims. Some guys will use a pair of pliers to tighten the stem bolt 1/4 turn past finger tight to ensure a good seal. The valve core is removable, which makes it easier to push a lot of air through them and seat a tubeless tire. You can also replace the core if it gets gummed up with sealant, without replacing the entire stem (handy).

I bought these tubeless valves for my new carbon wheel set. The wheel box came without the provided valves for some reason. The valves I bought from Amazon are now installed and seems to be doing the job. My Continental tubeless tires are maintaining the pressure and that’s what’s important.

Installed on my Reynolds Strikes with 60mm rim depth. Seats in the rim and seals better than the stock DT Swiss valves that came with my bike. The DT Swiss valves have a tendency to move when going over bumpy surfaces causing leaks, these have stayed snug. Will definitely buy again.

After this last season of riding I decided it was time to replace some parks on my Santa Cruz 5010c. I chose this blue valve stem for my mountain bike for looks and to be reliable. The valves were easy to install, had very clean threads and the selected color was nearly exactly how it looked online. Thus far they have been air tight and have had a few winter miles ridden with no issues at all.

These stems are well made and look really nice. I've had them installed for 2 weeks now and they have functioned flawlessly. It was really easy to remove the valve core and add sealant.
