MichelinA3 Airstop Presta Tube(Return to Product Page)

Bought these tubes at the same time to match up with newly purchased Michelin City 700 tires for my and my wife's Hybreds....put them on myself and had no problems with the tubes fitting properly in the tires. Perfect Match!

Bought two A3 Airstop tubes. After about 300 miles, the reinforced rubber where the valve stem meets the tube gave way. I will give two chances, but not three.

Am using these tubes on a Cannondale Hybrid. The tubes are well-constructed, unlike the cheap tubes carried by my local bike shop. The stem length supplied is just right for the rims. The tubes installed easily and hold air well. They are a good cross between light and durable. I bought an extra tube to carry around in case of a flat. The shipping was fast and accurate and the prices reasonable. A good first-time experience with this vendor.

I got very tired fixing flats on my skinny go-fast tires. I figured I wasn't saving any time by going fast and fixing flats so I went with the Michelin City and the matching A3 Airstop tubes. It's been over a year and well over 1500 flat free miles later I finally picked up a thorn. That reminded me how nice it's been not having flats. Yea! If I ever wear out the tires, I'm going to do it all again.

I bought two of these tubes to go with new Michelin tires, when arrived one tube was hanging out of the box, had large hole in it, in other words dead on arrival,other tube was Ok. Not worth the hassle to send back. Won't buy anymore of them.

Great tubes, got about 500 miles on them, not a single puncture. I also noticed they don't leak air as much as standard tubes. Less topping off. I did notice they were slightly heavier than standard tubes...

It's always a crap shoot when I order new tubes because I don't have to buy them that often. I commuted for years on the stock Bontrager race lite tires that came on my bike. I never changed tubes and I never changed flats. Those tires are TOUGH! But, they are really hard and narrow so I changed to some wider tires this year and the first set of tubes I bought with them were some no-name bike store tubes. The goat-heads made pin-cushions of them in a week! But with these Michelins, I have yet to have a low tire, let alone a flat. I checked the air pressure at least once a day the first week and checked it once a week since then and have not had to add any air. Heavier to be sure, but I needed more training weight anyway ,-)

I have around 200 miles on these tubes at the time of this review. Installation was easy, valve and keeper nut seem of good quality, and so far the ride is great. I run my bike with 70 PSI of air in the tires and over a couple weeks I haven't really lost any PSI of pressure when I put a gauge on.

I run them with tire liners on city streets. (lots of road hazard here) I have not had a flat for 4-5 months. I ride 75 - 85 miles a week .

I would definately recomend this tube.

What can you say about a tire tube? It holds tire pressure

Have been using these tubes for a few years now, they hold up pretty well. I ride 1,300 mi. a year, mostly on the road, still get one or two flats a season, but that might be in part to well worn tires. They hold air pressure much better than an average tube, I always try to keep one of these on hand, but last year I had a flat and the bike shop put one of their tubes on the front wheel. I noticed after a couple weeks the wheel with the Michelin tube will have 10 lbs. more air in it than the bike shop tube.

Had a pair installed a month ago, so far its holding air tight with constant on the trail usage. Bought a second set to use as spairs
