Schwalbe

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.

Great grip uphill and down on loose rocky surfaces. Have also descended some pretty chunky stuff and they have withstood the durability test. Haven't ridden enough on pavement to have a strong opinion there yet, but if you ride rougher terrain, I'd recommend these. No issues with seating the tire tubeless and no punctures yet.

I needed these for a big ride my friends and I did in California. We rode some gnarly descents and some fast gravel roads. I could have used a little more knobs on the loose stuff. They roll really fast in gravel and roads. Cornering was ok and climbing was no issue. Plenty of grip.

I've been very impressed with the Schwalbe One tires. They roll fast, feel smooth on the road, and provide excellent grip in both dry and wet conditions. The puncture protection gives me confidence during long rides, and the durability has been outstanding. Installation was easy, and they work perfectly with inner tubes. Great value for the performance. I would definitely recommend these tires to any road cyclist looking for a reliable and high-quality all-around tire.
