Review by DonWA

Hard to find smooth stem

I only use smooth stem tubes on my bikes as they do not tear up the o-ring seal on my pump. I still have not figured out why the unneeded threads were ever put on stems in the first place. Smooth stem tubes in this size are almost impossible to find. However they are available here at a decent price. As long as they continue to be available here I'll keep coming back. These are good quality tubes too. I have been using them for many years and have never had a flat due to a fault of the tube.

Fails by splitting on seam
by Gitane
Cycling Enthusiast

I've had two of these tubes split on a seam while riding. The second one lasted ~ 500 km and failed. The split (not a pinch flat/snakebite) is too long (over an inch long) to patch effectively, so trashed both tubes. Haven't had this problem with the A1 tubes.

I put these in my 'around town' or winter bikes. I'm sure they are a little heavier than performance tubes, but don't care. No troubles at all with these.

Works well - no flats so far
by BillyBob

We frequently encounter pointed garbage on the paved and gravel roads we ride, on old our time Trek bikes that are older than most of the kids out there riding. We mainly ride paved and gravel mountain roads in the mountains of San Diego County. We also ride mountain bikes, but we are not using this product on off road bikes presently.

So far no punctures, but we also use good tires (Panaracer Protite) and good cotton rim tape (Velox).

We use these tubes in a bike share fleet .

They hold air well and do not flat as often as other brands that we have tried . I can never remember ever having a split at the seam which is note worthy .

Best for holding air
by B''ham Biker

I especially like the smooth stem, it is much easier on my pump hose clamp than the threaded ones. Other than that it excels at holding air, until it doesn't due to a puncture!

Great for people like myself that hang on to older bikes. Sooner to later you need new tubes. These cover the issue.......

Amazingly reliable tubes

I have been using Michelin A2 AirStop tubes on my Schwalbe Marathon Supreme and Marathon Plus on my touring city bike for the past 8 years. I have had only 2 punctures in that time.

The first puncture was on my first ride with this tube tire combination because the shop mechanic who installed them had left a piece of wire inside the tire. My first ride was a 200k randonneuring ride and the wire inside the tire wore a hole in the tube after about 75 miles of riding. I replaced that tube with another AirStop and ended up getting 8,000 on that set of tires and tubes without any more flats.

The second puncture was on my second set of tires and happened because I ran over a horseshoe cleat and 2 nails punctured my front tire. Even though the nails went all the way through the Schwalbe tire into the tube, I was still able to ride my bike 2 miles home and never even had to add air to the tube on the way.

I originally discovered these tubes not because of their resilience, but because of their smooth valve stem. I have been riding tubes with Presta stems since the early 1970s and worn out several pump head gaskets on threaded stems. I switched to Michelin AirComp (700x23c) on all of my road bikes and Michelin AirStop (700x32c) on all of my city and touring bikes. Those are the only tubes I will buy.

Holds air better than the competition. Reasonably puncture resistant. Only knock is the cost compared to others (Kenda, et. al).

Disappointed in rubber quality and spot thinness that resulted in little tube aneurisms, one of which ruptured, flatting me on dirtgravel.

I like the threadless stem

I've used Airstop 700x18/23 tubes for years. They seem to have a good balance between weight and durability and I like the threadless stem since it doesn't tear up the pump fitting. I recently switched to 700x25 tires and moved up to the 700x25/32 Airstop tubes. They seem bulky relative to the tire size and tube changes don't go as smoothly. I think the weight to durability ratio is probably not as favorable, but I can't say that's translated to any noticeable difference riding. I do find the 700x25 tires incredibly comfortable so will not be going back, but might try other tubes if something catches my eye.

Great Tubes for Cross Tires

Great tubes for the bike. They aren't too heavy but provide a good overall feel in the tires. I buy these mostly because I like that Michelin A2 Airstop Tubes have the smooth valve option instead of the threaded valve. These tubes generally resist punctures well but no tube is puncture proof or snake bite proof.

About 1/4 of the ones I've bought are defective - weaknesses in the wall cause some areas to balloon out. The others work just fine.

I used these tubes for years, then I quit biking for awhile. When I came back to it I tried some cheaper tubes to save a little money...big mistake. Of the 20 I bought, 5 had valve issues imediately and the rest made it one or two rides at best. My ride takes me through an industrial area (most of the way), but still. I went back to the A2s and I'm very happy with the quality and durability.

Ive used a lot of these tubes over the last few years. They hold air pretty well and dont give me any pinch flats. The only reason Ive had to replace them was cuts from glass on the road, and no tube is expected to withstand that kind of damage. Will definitely keep using these.
