Michelin Airstop Butyl Road Bike Tube (Presta Valve)

I've put several hundred miles on the tubes and they work great. I bought a bunch of these at the same time to save on shipping. Will definitely buy bunches more for the holiday season.

Pump's head comes off the smooth valve much easier than off the normal threaded valve. It's a small thing but I found it very pleasant to use.

I also used Maxxis' and Continental's tubes. In your hand, Maxxis feels the flimsiest, Michelin is in the middle, and Continental feels the toughest. However, I didn't notice any difference in reliability while commuting 100 miles per week. Nearly all failures were punctures by external objects, which would probably puncture any tube. Even if one of these is more reliable than the other, folks like me would probably not be able to tell.

But threadless valves are way cool!

I was very surprised at the quality of these tubes in comparison to others I have used. I always assumed a tube was a tube. Well these tubes hold air very well, the presta valve seems to be more precise than the others and the butyl rubber seems to be more supple and have a different look and feel in comparison. Additionally, these tubes seem to be competively priced.

I am impressed with the quality of these tubes right out of the box. The valves are well constructed which makes me happy since this is usually a fail point on other tubes. Overall a nice quality tube at generic tube prices. However this is not thorn resistant territory and if glass gets through your tire these tubes will puncture but that is more an issue with what tire you have.

These French manufactured tubes are far superior to the "generic" tubes sourced from china. Molding is consistent, the valve is smooth and mechanically correct, dosen't tear up your pump head. Never have those "mystery" flats with these tubes. Do yourself a favor, spend a few cents more and ride with confidence, you'll wish you did when your changing tubes at the side of the road. Jerry
