Like most, I appreciate good tubes when I get flats. It's rare but the only time I think about it. I like to have two because when I do flat, I tend to have another or two within a week. It's weird, always works out that way. I made a mistake on my order, a 650 instead of a 700, but Western sent me a 700 immediately without a question. They're great and reliable.

7 YRS TOURING UPSTATE NY ROADS RIDING APPROX 2000 MILES PER SEASON I HAVE HAD A FEW FLAT TIRES ! LIGHTWEIGHT, DURABLE AND LONG LASTING .IN A PINCH I HAVE TRIED BIKE SHOP INNER TUBES FROM 2 LOCAL SHOPS AND ALWAYS COME BACK TO MICHELIN AIRCOMPS. MAILORDERING THEM IS A PAIN BUT WORTH IT. I ALWAYS GET THE SMOOTH PRESTA VALVE - DO NOT LIKE THREADED VALVE STEMS.

May need to run a slightly longer stem than with a threaded and nut style as stem pushes into rim. Not a big deal using pump, but I did need to get a different type of CO2 inflator that grabbed the stem and used a trigger, as opposed to my previous one that released gas when pressed onto stem.

Like the smooth, non-treaded stem. Much easier to get my floor and frame pumps on and off. Lighter than the butyl tubes I've been using but still holds pressure for days and have not had any puncture issues. 52 mm stem is perfect length for my Campy Eurus rims.

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.

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.

These seem to be very high quality tubes. The rubber in the tube is very uniform in thickness and when inflated outside the tire there is no ballooning in one area and constrictions in others. I have had however, problems getting them mounted and not having pinch flats. The pinch flat always seemed to be at the base of the valve. I finally realized that the reenforced area at the base of the valve doesn't like to bend very easily and let the tube slide past the tire bead and seat inside the tire. These tubes also don't seem to have as much powder on them as many other tubes do and because of this they hang up on the tire pretty easily. Recently I started using Ru-Glide, which is the mounting fluid used on car wheels and tires, when I replace a tube. This seems to have fixed that problem by allowing the tire and tube to slide by each other. Ru-Glide can be bought at auto parts stores. I highly recommend the tube.

Michelin A1 Tubes The Best

Been using these for years and nothing quite measures up.

Like Stems don't have threads so they don't tear up your pump's grommet (rubber ring that closes around the stem when pumping). It's very hard to find tubes without threads anymore. They also come in different lengths, accommodating different depth rims. They are light as well.

Don't like They're not the cheapest!!

These tubes are probably the best on the market, and throughout the last 20years of racing and long distance riding I have used many others. I used to use latex for the weight savings and suppleness, but started getting pinch flats quite regularly. Switched to these a few years ago and never looked back. They're only a few grams heavier than Michelin's latex, but exhibit similar ride quality and offer superior durability. We all know that low rotational mass is key to quick accelerations and effortless climbing. Paired with light racing tires you can easily shave off 200300grams from your rotational mass and that ladies and gents is huge.

I have never had a flat nor blow up tire since I use this product. Very light and dependable tube. The only thing is they only come in 60 mm presto valve. I have 58 mm zipp 404 wheelset and I need 80mm valve. I hope they will make 80mm valve.
