The Continental Tour 700 Tube is well constructed and has a nice weight and feel. I've bought some other brands that were very thin and didn't last as long. Fits perfectly in my 700x32 tire and I like that it comes in a Schrader Valve which is what I prefer. Overall, an excellent tube at a reasonable price!
What is there to say, they are tubes, bought 4 of these for two bikes I was fixing up to give away, priced right for sure and no problems with them. BTD got my order to me quick as always, which to me is a plus when buying online.
I used to get my tubes through Performance bike, but constantly had manufacturing defects. These Tubes just feel more quality and it gives me confidence that when I need to use my spare, it would have a flaw and fail to inflate.
Installed the tube on new tires purchased at the same time. If you need a refresher on how to install tubes, read the instructions on the website before you damage the tube. I have had the tubes in for over 2 months now and have not need to add air. My tire are 700c x 42mm. I have put on about 100 miles, so not very much. Tube is holding up well and I like the metal stem.
