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
No problems with valves or installation.
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,
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.
Nice but more expensive than other tubes that seem to function just as well less money
I use these tubes with Vredestein Fortezza Senso tires and generally have flat-free seasons. I ride 1000-2000 miles per year on rural upstate NY roads. I like these tubes because they are light weight and seem to hold up well.
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.
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
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.
Nice Tube had one pinch flat, would buy again.
I have not ridden on these tubes very long. They have not put me on the road side with a wheel and tire off cursing at the tube. I did have the opportunity to give a tube to a stranded rider and she recognized the tube and liked them.
I use the MICHELIN A1 AIRCOMP ULTRA LIGHT TUBE on all of my bikes (3). Although I have had a flat once in a while, I prefer this tube. The smooth valve stem does not damage my bike pump.
I bought two tubes both failed in less than 100 miles of riding. forget about saving weight and buy something more durable.
these tubes are fragile so be careful mounting them. I will stick to normal tubes, the weight savings isn't worth it
I change tires and tubes the day before a triathlon then change back to use for practice
Very good last a long time
