Continental’s lightweight Supersonic Presta Tubes are an easy way to drop weight on your bike. Dropping rotating weight also has the advantage of improving acceleration.

That 55 grams is for the 60mm valve and includes the nut and valve cover.

  • 55g (60mm valve, nut and valve cover)

Bad idea!
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.

CONS: Go Flat On Their Own

Super light weight, smooth ride
Great way to save significant rotating weight. They do not leak unless punctured, which means you rode over something capable of puncturing your tire & then the tube. In my opinion your tire determines the puncture resistance, the tube just holds air. Price is high.

Good for use with some sealant in them
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.

PROS: Lightweight

CONS: Leaky Without Sealant

BEST USES: Gravel Grinding, Road Biking, Casual Riding
