Great valve stem for tubeless conversion
Universal fit works well with any rim I've had. Easy to install. Seals perfectly everytime. Removable cores are nice feature.
These babies work!
I have a history of issues with tubeless valves not working properly. So when it was time to change out my Mavic valves (on my mountain bike) i was a little nervous. Couldn't beat the price on these Stans valves from REI and gave it a shot. I had ZERO issues and they worked correctly from the get go. Also, I lose very little air between rides which was not the case before. I'm definitely sticking to Stans from now on.
Solid valve stems
These work great with any tubeless wheel setup. They have a high rubber shoulder keeping air and fluid in. Other than that, they work as advertised.
They’re good
I put these on my bike and now I use them as a conduit to put air into the tires. They are small, and made of metal. They’re cylindrical in shape and hollow in the middle.
Worked as expected
I used these on my DT Swiss M 1900 wheels. I wondered if I should have gone with the DT Swiss brand, but these worked just fine. I used the Stan's NoTubes tire sealant and everything seems to be working as it should. Very satisfied with this product.
Beefy Stem
This stem is beefier than your regular presta valve. It actually inserts in my shrader valve hole for my pump. As a result, it feels sturdier and less fragile than your normal presta stem.
The standard for tubeless stemms
I've used these stems many times for tubeless setups and they work very well. Lock them down tight, though.
Tubless is the way to go!
These valves along with Stan's Sealant is a winning combo. Couldn't be easier!
Works as expected
Got these for my maiden voyage into tubeless. Installed very easy for a first timer (I was a bike mechanic in the 1980s). After 1000+ miles of abusing my mountain bike, not a single problem.
Garbage
Fell apart when I tried adding air to fix a flat on the trail. I partially blame a poor working pump, but these valves should be able to handle some light refilling. One fell apart after a month...
