Comments about Continental 700C Supersonic Presta Tube:

These leak air like a sieve on their own but with 125ml of Stans in them they make a great lightweight self healing tubeset for road, cross or gravel grinding.

      Comments about Continental 700C Supersonic Presta Tube:

      Installed Front and rear. Pumped up to full pressure and let them rest overnight. Stopped after riding 10 miles. One half hour later went to get back on bike and rear tire was flat. Replaced with 70 g tube I have used for years without problems.
      When I got home checked this tube and found a very slow leak at the area of the transition from the stem to the main part of the tube. So far the front is okay. There was some twisting around the valve stem when I installed which I straightened out but it appears these are so delicate that any kind of stress can cause a leak.
      Checked reviews on other sites and my experience is not unique. Unless you are very careful or incredibly lucky these tubes are a bad idea. The risk is not worth the 20 g savings.
