Great concept and a big improvement over presta, but one failed
I was glad to install these valves on my gravel bike running tubeless tires. They are much easier to use than old school presta valves and flow a lot more air, which helps with seating tubeless tire beads; they also haven't clogged with sealant like presta or Fillmore valve stems. However, one valve has been solid and leak-free, the other developed a major leak that I could not stop despite disassembling and cleaning the valve. I needed to swap it out for an older Fillmore valve before riding again. I'm going to chalk that up to a fluke or defect in that particular valve stem rather than an issue with the design.
