Review on 🚲 NoTubes Stan's Tubeless Road Valve Stem - Rectangular Stopper: The Ultimate Solution for Effortless and Reliable Tubeless Performance by Jake Davies

I bought these as I had a major problem with air leaking in the stock and thought they would be a great replacement. I installed them and still have a major stem leaking problem. I've since added an o-ring under the valve nut from an old tubeless setup and the seal around the valve seems better, but I'd recommend looking for a different valve if you need reliability. Update: The problem was not with this valve stem. was at my work with rim tape. Once I rewind the wheel, these stems work like a champ!
