MichelinA1 Aircomp Ultra Light Tube(Return to Product Page)

I purchased 2 Michelin A1/B1 Aircomp Tubes to go with new tires (700 x 23). Have used these in past with no problems. This time, had problem with nut on end of threaded stem coming completely off threaded stem . Usually, the end of thread is flattened over to keep from threading right off. Not on these. Also, with smooth stem, when I got up around 100 PSI, pump head would pop off valve stem. Maybe my pump is worn, but I have other wheels with smooth stem tubes and have no problems. On positive note, once I got nut threaded back on and got air in tube, they held pressure fine. Even seems like the held pressure longer than normal. Go figure.

I have used Michelin tubes for years with really good luck.

I buy these tubes because they can be rolled up into a quite small package which is perfect for a compact seat bag. They are tough enough to use every day and perfect as a light, small spare.

This is a case of you get what you pay for. The tubes are a bit more expensive than others but over the last ten years they have been uniformly good quality, and more supple than the heavier cheaper versions. I really like the smooth valve stems, they do not tear up my quick connect hose fitting, easy to pull it of quickly as I release the grip all in one motion without shredding the rubber seal.

Great value and longevity for a light bike tube.

I lost 2-tubes in the space of 2-days. Consequently, I researched the product, because I like the Michelin brand, and opted to buy its rubber alternative,

These tubes are probably the best available. I've used others that have deflated while just sitting in my car. No such issues with these.

Good lightweight tube. I always buy 18-23 sz for my 28 wide tires.

Quality, I see it in this product. I am a more light weight rider at less than 140lbs so saving a few ounces here and there does go a long way. I could feel a difference with these tubes over cheaper alternatives. I did not see or feel anything negative...these tubes are all good!

Good buy for the money

I ride a road bike on city streets.

No problems with valves or installation.

I used these tubes for many years. They are light (the most cost-effective way to take some grams off the bike) and reliable (I did not experience any more flats with these than with regular butyl tubes). I also like the smooth valve stems, which work better with the Silca pump heads. BUT , like many other cyclists, I have switched to 25mm tires, on wider rims, and may try 28mm next time I need tires. Michelin desperately needs to get with the program and release a 25-28mm version of this tube.

These tubes hold air very well. I do not have to pump up every ride. So far they seem very strong no problems so far and I love the threadless stems

These have been my go to tubes for years. Longer stem lengths mean I don't need a valve extender. And not having threads saves my floor pump grommet.AND, BTD always has the best prices.

The only tube I use and I have 5 racing bikes, Available in three stem lengths for different rims and smooth stem which doesn't abrade my silca pump head.

Great tubes. I believe, these are as good as any other butyl tubes out there. I've been using these for several years. They are light and no more prone to flats than heavier tubes. I also like the unthreaded valves.

Very lightweight, which is great for climbing. I have used them for years without any problems with puncturing, etc. Variety of stem lengths available.

I use the product 3-4 days a week on my daily rides and have always found them to be very reliable product over my 56 years of bike road riding.

Reliable tubes. Light but not flimsy.

Good 60mm smooth presto valve stems.
