Very reliable for everyday use .

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 .

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.

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.

Best tubes you can buy

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

A good tube but . . .

Bought 4, 3 have worked well with no problems. One of them ripped a hole too big to patch when it was unfolded.

QC lacking

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.

Good, buy an extra one

They seem fine for the purpose, if you can get one without a pinhole. BTD credited the purchase but cost me riding time. Also, Michelin is a French company, the stamp on the tube says Made in Serbia

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.

Cheap but unreliable

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.

Reliable tubes!

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.

A good, decent product used for its intended purpose.

I bought it for its smooth presta valve and works just fine for an easier on/off during inflation.

These are for a commuter with normal size tires and rims. I like the unthreaded stem that should help with pump seal longevity.

Great deal, even when not on sale.

I use a racing bike as a commuter in the city. It makes it so keeping up with cars and riding on the streets is less rough. However, with all the bumps, potholes, glass, etc using full blown racing tires and tubes is a pretty bad idea. I try to find the balance of durability and speed. Right now I have Gatorskin tires, a PVC liner, and these tubes and things are going great. With this setup I've only had one puncture in the last 6 months (used to be one a week), and I can pump with High PSI to still have good performancedurability. The added rotational weight is present, but less than other tubes and the price is good.

Airstops are the best. They just don't lose air and seem to help good tires resist punctures.

Smooth. Pump them up and weeks later you are at 90%. They seem to help good tires resist punctures. Don't ask me how.

High quality tube

I have been using these tubes with the Michelin Mud2 tires for cyclocross racing. They are most resilient tubes I have used. A small puncture only resulted in a slow leak and I was able to finish the race. I have pinch-flatted on one occaision, but that comes with the territory.
