MichelinA1 Airstop Tube(Return to Product Page)

These tubes seem to be the most reliable for the price. 52mm valve stem is excellent for deep rims, and the non treaded surface is easy on floor pump gasket.

I've used many different tubes over my 30 years of bicycling and Michelin hold up the best for me.Love them

Installed this tube for my road bike and road the bike for more than 200 miles and so far no flats and still counting. I will recommend this tube for recreational cyclist like me!

These are products I routinely order and I am always satisfied with the performance and price

I've used one, bought several, gave a couple to friends, so far, so good

These tubes are top quality and the non-threaded valve is the perfect diameter for a Silca floor pump and offers a good surface for a hand pump to seal onto.

I use these tubes on three road and two adventure bikes and have had no flats with literally thousands of miles of use. The french valve has thick rubber on the base of the stem inside the rim which is conical shaped and has eliminated the annoying tube cuts at the valve.

I only have used the tube for one ride. No problems. I bought some Kenda tubes and they didn't last long. I think the rubber was defective.

Airstop tubes gives me some added assurance. Most of cycling is in confidence that you'll get through the ride, regardless of anything!

I've been using these tubes for a while on my road bike. Just the right thread length (with other options) and like the smooth valve to not tear up my pump.

Good product for a good price. I like these Michelin tubes. Not the lightest but a great combo of reliability and weight.

First tube I tried on my rear tire on my Road Race Bike blew after cycling only 1 1/2 miles. I was angry seeing I was on my way to an appointment. The send tube I'm on seems to be holding air after 2 days of use.

I won't purchase this type of Michelin since the first one blew under 2 miles of cycling. I inspect the whole inside of the tire and notice no kind of puncture. Only switched to this tube because it was cheaper.

I'm going back to the Michelin UL 700 x 18-23 52MM PV. I'll spend the extra Dollars for a lasting inner tube.

I'm a Serious cyclist since March 2011 using my bicycle as my main transportation.

200 miles no problem. the lack of threads works suberbly on my silca pump. will never get threaded valves again.

Bought several of these tubes, price is right and I've never been wrong with the Michelin man!

I have been very happy with the airstop by michelin. It rides exceptionally well, is almost as light as a lot of race only tubes, without being as prone to puncture as the lighter tubes!

Great tubes for all around riding. Not the lightest tube on the market, but they will keep you rolling.
