Continental Supersonic Presta Tubes
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. The Continental Supersonic Presta tube is offered in different valve length options and according to our Jenson USA scale weighs in at 55 grams. That 55 grams is for the 60mm valve and includes the nut and valve cover.
- 36, 42 and 60mm valve
- Presta Valve
- Removable Core
- 55g (60mm valve, nut and valve cover)
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.
