Michelin A1 Aircomp Ultra Light Tube

I have been using these tubes for 3 years. I like them Alot. They are lighter than a regular butyl tube and hold air just fine. I check my tire pressure Everytime I ride but there have been a few time the sat overnight and they are fine for a couple days. Very pleased with my tube purchase and use.

Great performance in a tube. Like the thread less stem - works better with pumps.

The only tube I use for all five of my road bikes.

Great tubes! Terrific service! My 1 source for bike products.

Super, consistent quality. Light weight but hold pressure well. Long, un-threaded valve stem preserves pump gasket.

I have used the tube in rear wheel as replacement after punctures and it has worked great. I got few flats and needed to patch the tube but I believe those were due to using the 18-25c tube on 28c tire with 85psi pressure. In this case the rubber is stretched to its limits making the tube very thin that it easily breaks on hits.

This is possibly the worst piece of cycling equipment I have ever owned. Everyone of these tubes have leaked from the stem valve brand new out of the box. Save your money and buy a tube with more durable stem valve. Its no fun being stranding great distances from home because the stem valves in this product are faulty. Shame on Michelin for manufacturing such crap!!!

Needed long valve stem and lightweight tubes for a set of aero clincher wheels. These do the job well and fold small enough to fit easily into my seat bag. Valve stem is smooth so it does not chew up my pump head and valve core is removable.

No flats so far.

One of the only brands with a solid (non threaded) shank. Does not wear out the pump seals so your pump will last longer!

I run the lightest front and rear tires available so makes sense to use the best butul tube. Nothing I don't like about it.

I changed two bikes from Kenda tubes to the Aircomp to get a lighter more supple tube. Running Pro4 Endurance tires with these so the tube is well protected. After just over 1,000 miles I have had no issues, even with tiny nicks starting to show in the tires, and some very rough riding on beaten roads and some gravel down in So Cal. They do feel better and getting rid of weight at the rim is certainly helpful.

I used these tubes with my Michelin Pro4 Service Course and they work great together. The tubes are light and quite durable.

I ride approx 2000 miles per year on mostly rural roads. I hate getting flats but sometimes ya hit some little piece of something and psssst...ugghhhh...l need I say more ?.... When i start the season with new tires and tubes these easily last the season. Been using Michelin Aircomps with Vredstein Fortezza TriComp tires for the past 5 or 6 years.

I have been riding the Michelin A1B1 AirComp tubes on all of my 700x23c tires ever since I first discovered them about 12 years ago. The initial selling point for me was the smooth stem. I top off my tires before every ride and the threaded stems were wearing out the rubber gasket in the head of my floor pump. Sometimes I almost couldn't disengage the pump head and had to apply so much pressure I was afraid I was damaging the valve stem. The smooth stem AirComp makes adding air a breeze (no pun intended).

The slight extra cost of the AirComp over other tubes is easily offset by the cost of pump head gaskets or, in one case, a whole new pump since I couldn't find a gasket.

I have also found the AirComp to be very durable. If all goes well and I don't get a puncture from the occasional glass or nail, a tube will easily last through 2 or more sets of tires. This comes out to 6,000 miles or more.

Been using these tubes for a few years. They are nice and light; rotational weight does matter. Don't get more flats than with heavier tubes. I also like the smooth valve stems.

Fantastic tubes and I have used them for years.

I buy these tubes because of the smooth, non-threaded stem. Tire pump slides on and the valve fitting on my pump and doesn't get abraded and worn out. They hold up well. This is the only tube I buy.

Great tube (surprisingly light weight for the price and I like that the stem isn't a) too long (40mm instead of standard 48) or b) threaded.

Can't ask for anything more out of a tube you bought on sale.

I use Michelin tubes in our bike tires because they work well and this model has a smooth valve stem. I detest threaded valve stems because they tear up the seal on my Silca floor pump. The lightweight tubes last just as well as regular weight tubes so I now use them exclusively on the six bikes that my wife and I own.
