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!
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.
