MichelinA1 Airstop Tube(Return to Product Page)

use on 700 series rim (27) -bike is primary transportation and often carry 70 lbs loads in two saddle bags over rear wheel and basket over front wheel

Reliable tube for 23mm tires. Not threaded so doesn't include a nut but that's not really needed anyway. Probably not the lightest tube but that means it won't puncture so easily. Coolest thing is it is smooth so easy to put the pump in and off.

Solid tubes at a good price. I have not had issues with quality.

I like these tubes. They last a long time and I like the smooth stem.

I use these for training and racing and love them.

This product did not make acceptable pancakes, and had a distinctively rubbery taste no matter how much syrup I used. As a last resort I tried putting it inside the tires of my bicycle, and was delighted to find that it did a perfectly serviceable job of retaining air at 120 psi, at the most reasonable cost I could find on the interwebs. And that is all that I look for in this sort of product.

Great value on sale price.

The Airstop tube is a good value for its dependability. I haven't had problems of it tearing at the stem, which seem to be the weak link with some other tubes. I get the expected mileage, with fewer flats than with some of the other tubes.

I use these for my recreational rides. Very few failures. they are better than average at keeping the pressure.

A bike tube is a bike tube right? Well maybe, I have used many brands and for some reason keep coming back to Michelin A1 Airstop Tubes. I am using them with my

Michelin Pro4 Service Course Tires. About 400 miles on them so far no flats or problems...

rails to trails riding 120miwk

Retains air like none other. Best I've used. Highly recommended.

I use the 40mm valve stem for my standard wheels. Performs as expected.

Put them in no problems at all

These are great tire tubes that last. They hold air a lot longer than other tubes. I had a Specialized tube in one wheel and a Michelin A1 Airstop in the other. The Specialized tube would lose air after a few weeks without use, while the Michelin would still be at the original inflation level.

Used continental before and had too many flats, no flats since I changed to Michelin.

I love this tube compared to factory originals. Stem is solid, not flimsy. It works well with my pump.

This tube seems to be true to size and has held up well.

I am using it in a road bike riding using a hwy road tires hold great to the floor

and the tubes fell great smooth and flexible

Picked up a metal sliver 20 x .5 mm. Didn't notice it on the ride, but the tire was down to 60 lbs pressure (from 110) the next morning
