MichelinA1 Aircomp Ultra Light Tube(Return to Product Page)

it just fits and seems to work perfectly. only one flat, hit a rock going 37 and it broke the tube. was able to ride it out-rear.

I ride very hard and prefere a low rolling resistance , I like quality and demand it from products I but.

I will not buy these ever again, I have had lots of flats with them doing just regular 50 mile bike rides, 3 times per week, on my road bike, and 3 of the 8 tubes, had faulty valves, and leak air when trying to pump them up, right out of the box. I will never buy these again.

Most air must let out to fill. Smooth valve allows head to come off easily

These tubes are quite reliable and I like the smooth valve.

I like this tube, because it's made well. I also like the smooth stem, and the 60mm stem option.

Just a note of caution. These presta valves are non threaded so that if you carry one as a spare and a CO2 cartridge, you may have trouble attaching cartridge to the valve if is a screw on type .

Lightweight durable tubes that I've been using for years. Besides their weight & durability, I really like the non-threaded stems. They are great for airing up your tires, I can attach my Joe Blow pump without engaging the lock lever & pump the tires to 115 PSI, pull off the pump head & your good to go. Fast, easy!

I prefer unthreaded tubes because they don't chew up the gasket on my Silca pump. I generally use these tubes because they are pretty light as butyl tubes go. I have had a couple fail where the valve stem is joined to the tube. I use these to train for an ride century distance rides in season. BTD has the best prices I have found on these, especially if you buy 5 or so at once.

Michelin makes the best tires and tubes for the price and the stems are easy to work with when inflating unlike others who leak or break. I've been using Michelin for 20 years and will never change unless I win the lotto and can afford the premium tubes and tires that are out there...

These tubes are durable lightweight and hold for several days without needing any added air and the grooveless stems are an added bonus. My previous tubes needed to pumped every other day. Love the tubes....bought Four and will be buying more to stock up!! Go ahead and buy them you won't be disappointed.

I started using these about a year ago, and I absolutely love them. What more can I say, they are a great lightweight tire! The non-threaded valve stems are nice, and they seem to be easier to seat when mounting the tire. My flats have probably gone down by about 60% since I started using these tires.

Lightweight, great smooth stem so it doesn't tear up the pump head.

lightweight, reliable, durable. What more could you ask?

I have used these tubes for 30 years and have always had good luck. Quality is good, longevity is great, light weight, good puncture resistance and the smooth walled valve stem doesn't chew up the chuck on my tire pump. A great value.

Bought six of these tubes. Had a flat on the first ride. Replaced it on the road, that one flated within a mile. Got a tube from a fellow rider so I was able to get home. Next tube of the bunch deflated overnight. The tube used to replace that one wouldn't even take air. So I inflated all of them and did the water test to discover the problem all four had valves that leaked. I've used these tubes before with no problems, so I don't know if it was a bad manufacturing run or what, but I won't trust them again.

I got a few of these to save some more weight on my road bike.

Installed one, inflated and while working on another bike i hear an explosion. the tube blew up. put it another one, inflate it, pulling the pump valve the tube just ripped so another one was gone within 5 minutes.

Decided to suck up the additional grams and stick with standard tubes - no issue with these so far (and have been riding for 20 years).

So overall i think the value is very low and in some cases these tubes are probably dangerous.

Happy riding!

I used to think that Michelin made the best tubes, but I think something's changed in their manufacturing. I've had two of the last set of tubes that I purchased fail early, one at the valve stem and one developed a hole on the rim side of the tube. There was nothing that punctured it. I'm looking for a different tube.

I have had no problems with these tubes. Hold air reasonably well and are very light weight.
