Purchased new tires and wanted reliable tubes for my two road bikes. I bought two of these tubes and new tires last year for my Cannondale CAAD 10, rode the bike a lot during the summer and fall riding season. Never had any tire issues. A quality product at a reasonable price.
These are great tubes. I got some when I ordered some tires a while back. They hold air better than the Bontrager tubes that came on my Emonda. I've aired them up and checked them 2 days later and the tires didn't need any air. Can't get better than that. These are a steal as well, great price for such a great tube. I prefer the smooth Presta too, doesn't eat up my pump head. They may be a little heavier than other tubes but I'm not concerned about weight as I don't race. Going to stock up on them soon.
My friends and I are always in need of inner tubes. The Michelin A1 Airstop Tube is a bit pricey but always a solid well made product. When they go on sale, I pool our resources together with my friends and order a bunch of them. This is my preferred tube as I cannot remember any of them having imperfections that would cause them to fail without a verified tire puncture.
This tube worked well for me in a recent race. This was the first tube I used with a smooth valve stem and I prefer it. It is easier to attach and remove the pump and with high pressure tires, it seems that shifting of the tube's position is not a problem.
I have been using these Inner Tubes for many years now and have always had good experiences with them from a quality perspective. They are consistently well made and last. I cannot remember ever having one of them fail other than the normal punctures we experience once our tires get old. When these tubes go on sale I stock up on them. Even if they sit around for a while they still work as intended.
