MICHELINUnisex's A1 Airstop Inner Tube, Presta

Fried gave me a fresh Peugeot French racing bike. Had not road it in 20 years. I was riding it and ran over a goat head. Rear tire so it went flat. So I ordered gator skin rear tire and two extra Michelin inner tubes. Rear tire was a chore to take off after 20 years being on the rim. Well any way when inner tubes get can't wait to put in rear tire. So I can go bicycling again. Hopefully inner tube holds up. Worth the money having good inner tubes.

These are great all around tubes. I had some higher performance tubes and they lost pressure pretty quick. Like the name says they are "AirStop" and hold pressure for several days with only a few psi loss. Two things to consider. First they do not have removable stems so you cannot fill them leak stop fluid. I don't like the stuff because eventually it forms a ball in the tube and when you really need it all that happens is they leak a milky sticky fluid that gets all inside your tire. The biggest thing to watch out for is they are non-threaded and just a little smaller diameter than the threaded ones. If you have a pump with a clamp/release mechanism they are fine, but with the push-on type CO2 cartridges sometimes they don't seal well and can leak. Luckily for me I had two cartridges and the second one worked when this happened. If you use CO2 cartridges, make sure it seals well on the stem before you go off thinking you have a spare. I now carry a threaded tube as my spare.

I've put almost 400 miles on a pair of these tubes when I got my first flat after about 15 rides. I found that they held air pretty well between rides although I still had to add some air each time. Adding air for each ride is normal to me so I don't hold this against the tube. Oddly, I found that the tube was a little too long for my rim by about a half inch. The tube folded over itself. I don't think this caused a performance issue but it made the installation a little slower as I tried in vain to "fix" the overlapping tube. The price was competitive and it gave me no real problems beyond the slightly inconvenient installation. I bought 2 more so I guess that's an endorsement in itself.

I normally only buy Michelin tires, but i was running low and needed to stock up and found these Michelin tubes for a great price. Once my order arrived I need to put a one new tube on my road bike, but as I began to pump it up I noticed it had a hole in the tube straight out the box. I promptly sent an email to the seller stating my situation. I received an email response within 24 hours giving me an option for a full refund or the option for a new tube. So I took the new tube offer and a couple days later another package arrived with two new tubes as a replacement... AWESOME!Its wonderful to find companies who care about their customers, Thank you GREEN CANYON OUTFITTERSince this story about 2 months ago now, ive told a few of my cycling buddies who always buy tubes from local bike shops for $9 each, I told them to buy them online from GREEN CANYON OUTFITTERS and they will ship it straight to your front door

This may seem picky, but…Before I ever use a tube in a tire, I inflate it to check for leaks. I'm always amazed at the total lack of concentricity of most bike tire tubes. There is often at least one place on the tube where a large balloon pops up like an aneurysm just waiting to blow.Is it just the weakest part of the rubber? I'm not sure, but I know that it's not a sure sign of a defect as I've had leaks in other areas of tires more than at the balloon swellings.I can say that these Michelin's have aneurysms just like other tubes. But the rubber is thicker and they don't feel as "cheap".

These French manufactured tubes are far superior to the "generic" tubes sourced from china. Molding is consistent, the valve is smooth and mechanically correct, dosen't tear up your pump head. Never have those "mystery" flats with these tubes. Do yourself a favor, spend a few cents more and ride with confidence, you'll wish you did when your changing tubes at the side of the road. Jerry ...(time marches on)...... OK dudes and dudettes, three years later and over ten thousand miles, guess what? No flats on my touring bike..., oh, replaced the tubes when I put 32 x 700 gators on, just had to use my spare new/old tubes for something... I have over 1000 miles on these now about to switch them out on purpose haha

Use in on the wheels on my trainer-I get significantly less time before it leaks that other higher priced tubes-Not bad but not great.Trainers are notorious for eating tires and tubes so it is tough to judge how well it would hold up on the road.Just my experience-your milage may vary.

This tube loses only a couple of pounds per week. Other tubes seem to loos ten or more pounds in the same time (dropping from 115 to maybe 105 pounds). I would have given it five stars if it had a threaded barrel to lock it in place on the rim.

As the product description indicates. Very good quality product and quick delivery.

Arrived quickly and changed the tyre on my bike. I have been on some long rides since and they've held up great.

inconsistent product details. description says 700 X 18/23C tires; picture shows 18/25C.Shipped 18/25C will work, but I personally was looking for 23C.

only tubes i have used for more than 4 months without a puncture. 700c X23 tyres

Don't waste your money here, these were cheap $ but don't fit normal wheels (too long), are very thin/flimsy, and have a nasty stench - smells like a mechanic shop. Stay away.
