I use these tires on my gravel bike. I ride about 22 miles each day. Initially the tires were very stiff and cornering felt uneasy to me. After the first 100 miles, this effect was completely gone and corners nicely now.
Here in Arizona we have to deal with A LOT of thorns and goat-heads from trees and plants are really hard on tirestubes. I've got over 300 miles on the tires now and not one flat tire!
Bought 2 of these tubes. First one split at seam. Second got small pinhole, slow leak so does not seal
or stop leak as advertised. Just another overhyped overpriced cheap quality tube.
I have a 700c wheel set with the Michelin Transworld Sprint 35mm tires on them, which I also purchased here. These are the best tubes for overall use and commuting. They are light and strong, and have a nice polymer dusted on the outside, which feels great and mitigates the tube from sticking to the rim or being punctured by the tire when being inflated. And even if they are punctured, its worth patching and re-using them, which is better for your wallet and the environment. You just can't go wrong with these tubes so just go ahead and order 3 and you will be set for years. Thanks BTD.
Bought these tubes at the same time to match up with newly purchased Michelin City 700 tires for my and my wife's Hybreds....put them on myself and had no problems with the tubes fitting properly in the tires. Perfect Match!
Bought two A3 Airstop tubes. After about 300 miles, the reinforced rubber where the valve stem meets the tube gave way. I will give two chances, but not three.
Am using these tubes on a Cannondale Hybrid. The tubes are well-constructed, unlike the cheap tubes carried by my local bike shop. The stem length supplied is just right for the rims. The tubes installed easily and hold air well. They are a good cross between light and durable. I bought an extra tube to carry around in case of a flat. The shipping was fast and accurate and the prices reasonable. A good first-time experience with this vendor.
I got very tired fixing flats on my skinny go-fast tires. I figured I wasn't saving any time by going fast and fixing flats so I went with the Michelin City and the matching A3 Airstop tubes. It's been over a year and well over 1500 flat free miles later I finally picked up a thorn. That reminded me how nice it's been not having flats. Yea! If I ever wear out the tires, I'm going to do it all again.
I bought two of these tubes to go with new Michelin tires, when arrived one tube was hanging out of the box, had large hole in it, in other words dead on arrival,other tube was Ok. Not worth the hassle to send back. Won't buy anymore of them.
Great tubes, got about 500 miles on them, not a single puncture. I also noticed they don't leak air as much as standard tubes. Less topping off. I did notice they were slightly heavier than standard tubes...
It's always a crap shoot when I order new tubes because I don't have to buy them that often. I commuted for years on the stock Bontrager race lite tires that came on my bike. I never changed tubes and I never changed flats. Those tires are TOUGH! But, they are really hard and narrow so I changed to some wider tires this year and the first set of tubes I bought with them were some no-name bike store tubes. The goat-heads made pin-cushions of them in a week! But with these Michelins, I have yet to have a low tire, let alone a flat. I checked the air pressure at least once a day the first week and checked it once a week since then and have not had to add any air. Heavier to be sure, but I needed more training weight anyway ,-)
I have around 200 miles on these tubes at the time of this review. Installation was easy, valve and keeper nut seem of good quality, and so far the ride is great. I run my bike with 70 PSI of air in the tires and over a couple weeks I haven't really lost any PSI of pressure when I put a gauge on.
I run them with tire liners on city streets. (lots of road hazard here) I have not had a flat for 4-5 months. I ride 75 - 85 miles a week .
I would definately recomend this tube.
