These were installed on my touring bike rebuild. I wanted durable, quality tubes at a reasonable price. They are holding up very well!
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.
Tubes are tubes, right?
Seriously, I like that these are a bit thicker. I don't race. I'm not concerned about weight. I just like to think I'm going to go out and ride and come back without flatting. If these contribute at all to my security, they're worth it.
Also, I'm a traditionalist. I like that Conti uses a steel stem with a securing nut. Classic!
Good tubes hold air well just as a tube is supposed to. These are not the thicker style for puncture resistance but that not what you are paying for. These are a basic functional tube. Work well for what they are.
I have Matrix rims and tires are hard to mount. I,wasn't offered a tube , say 25 to 32. The 3w to 47 were a,challenge abd ended up pinchibg one
I use these Continental Tour 700 butyl tubes inside my bicycle tires. You can inflate them to keep the tire bead properly seated on the wheels rim and and that makes riding your bicycle very comfortable and it handles really well.
I have used a variety of inner tubes over the last 50 years, but the Continental Tour 700 IMO is the best and a decent value as well. In thousands of miles I have yet to see any failure at the stem area (a weak point in any tube) nor have I had any pinch flats. I check the air pressure in both tires before every ride. All tubes leak and these are on the low end. I only need to add air ever other ride.
Just mount them with some talc powder and off you go! No worries.
If you cycle the distance on road touring and carry loads such as panniers this is a must tube! The rubber is a bit thicker and more puncture resistant. They are extremely easy to install. They can handle large pressure without stress. I tour all the time and find the regular 28X32 road tube to thin and they rupture because of the added weight on the rear tire. Therefore, I used to run the tire at a lower pressure. With the Conti Tour tube I can blast the pressure up to extreme levels and no worries about blow out or rupture! Get these if you're serious about touring and want reliability! 5 Stars all the way!
