Michelin Airstop Bicycle Tubes, Butyl Rubber, Presta/Schrader/Regina/Wood, 26", 27.5", 27 x 1 1/4, 700c, 29", Road, Mountain, Gravel, Commuter, Hybrid Bicycle

These are my favorite bicycle inner tubes! I use them on my road bike and gravel/hybrid bike. They hold air an incredibly long time. I do no have to refill them for every ride as with all other tubes I have tried. Worth the money and slightly extra weight.

This is my comparison of the Continental Race 28 (42mm) and the Michelin Airstop A1 (52mm) both in 18-25 sizeBoth are nice products with actual confirmed weights of 97g, which are not the lightest but certainly not the heaviest on the market. According to my weigh-in, the Continental Race 28 comes in at 98g including the threaded ring (which weighs 1g) so all being equal they are the same weight (unless you're a total weight weenie)Michelin Airstop: Nice tire with non-removable valve cores and a smooth copper stem. The valve stem lengths are either 40mm or 52mm. Unfortunately the 40's get through a standard aero wheel (Mavic cosmic) but are still slightly short and the 52's are a bit on the long side, so I opted for the 52s (which came in at the same weight as conti's 42s). Seems that the physical tube is a bit snugger fitting in the tire around the valve stem than the continentals but overall no issue installing. Tire is also coated for easy installation.Continental Race 28: Removable core and threaded silver stem which, to me is a bit concerning as the cores frequently come out when unscrewing the pump (as many have pointed out) and despite locking them in tightly with a wrench, is less than mentally comforting when changing a flat on the side of the road. Valve stems are a nice length at 42mm for standard aero wheels and also comes in a 60mm which is a touch too long for standard aero wheels. Tire is not coated but installs easily.Overall they are both very nice tires with the primary difference being the valve stem. If you want a solid non-removeable core, go for the Michelin if you prefer removable threaded go for the Conti. Can't lose with either as both are reputable brands and the physical tires are nice in either case.

Easy to install excellent tire great traction

This inner tube is awesome for the price

I ride 16mi a day, work and fun. Just bought a Fuji Absolute 1.0 with Mavic OpenPro-105 hubs- 36 hole-3 over lace and 700x28 Ultra Gatorskins.Tubes were Kenda 700 x 28-32c Thorn Resistant with 105 psi the ride is a bit rough ( lots of rubber and not much flex). My back tube had a defect next to stem only one month old-300 mi. I sent a nice guy email 10/15/12 to Kenda with picture and they were very cool and sent me a new tube not Thorn Resistant there discontinued she said. In the meantime I bought a pair of AirStop and installed them at 108 psi for 700x28 Gators (95 psi) but they roll better and I'm 6' and 218 lb. I notice a much smoother controlled ride and turns are much deeper-fun- tires flex and has a better give like the Ultra GatorSkins was meant to, even at 105 psi. The stem and rubber seems well built and strong. Just now i pulled a goat head out...no leak :) I live in Albuquerque NM Green and Red Chile and damn-Goat Heads. No guarantees with flats..but I will enjoy the ride and carry co2 and a tube in my tool pack. Will patch if needed at home and order another set of AirStops. Hope this helps..enjoy the ride. Damn Goat Heads.. Not A expert, so i depend on reviews...keep it honest and simple.

I purchased 2 of these in April 2013 and stored them in the bag on my bicycle seat so they were readily available if I were to have a flat on the road away from home. I used one of them over a year ago and it's on the rear tire of the bike now. Last week I had a tire puncture and decided to replace the tube along with a new tire. As soon as I tried to pump up this tube to make sure it was in good shape, I discovered several leaks along the seam. Based on what I see, I would likely have to place patches all along this seam and who is to say, the rest of the seam won't separate and leak under pressure. It's like the rubber has deteriorated in the 2 1/2 years since I purchased it even though it's never been used. This is very disappointing and I will not purchase this brand again.

So far these are excellent. I mounted one in my rear tire and have a few miles on it already, and just mounted the second tube on my front wheel. The quality of these tubes appears excellent as each unfolds evenly and was easy to install inside my tires. I'm running them in a set of 27 1/4x1" Panaracer Pasela Tourguard tires, and will update this review in the future to tell how this combination performs. These tubes also do a great job of holding air. I pumped up my tires to 115 psi 24 hours ago and just checked the pressure. No drop at all. Also, the label on the box says that these tubes can be used on both 700C and 27 1/4 wheels. I've used 700C tubes in my 27 1/4 wheels for a while with no adverse effects. The size difference is negligible, so these will work with both size wheels.

I've always used these tubes. I was quick to reorder them at any cost when I got a puncture (due to the rim tape being in poor condition).When receiving these from Amazon, I inflated it up to check it. It feels of significantly LOWER quality than the ones I've been accustomed to. I also noticed a stamp that says SERBIA on it. The inflation was not even. It will be larger in some parts, and thinner at some parts. Even the one that got a puncture (after patching it), looked of better quality/condition. The ones from Amazon do not FEEL or SMELL the same as my original ones. I pumped both tires up to 95psi. Later that evening (6 hours later), I checked my rear tire (old Michelin tube) and it's still at 95psi. The new one was at 88 psi. It's just not the same any more. It just has the Michelin name. Even the box is different from the old one, sporting the same UPC. I'm returning these and won't even bother. Will probably move onto Conti tubes.
