Continental Supersonic Tube Review:

For a long, time I have wanted a set of Supersonic’s for my new set of wheels. I was considering using them for a time trial set up with smooth tires such as the Continental 300’s. Due to the extra thick butyl of the Supersonic tubes, and their ability to resist flatting, I would need to run narrow and low profile tires. Since my TT bike is much too light in weight for the Continental 300’s, I was hoping to use them on my new Gravel bike for its first real trip.

Upon receiving the first tube in the mail, I knew my new Gravel bike would be set up with Supersonic’s. The tube is a bit longer than I am used to but the tube has a very nice coating. The coating is thicker than most, including the Vittoria tubes. The green on the Continental tube is a bit more subtle than on a Vittoria tube.

After inflating it, it is evident that the tube is slightly heavier weight than the Vittoria tube, but not as heavy as a Michelin tube. After comparing the weight of the Supersonic and Vittoria tubes, one can certainly tell the difference. Comparing the length, the Supersonic was equal to the Vittoria tube but it appeared to be just a bit thicker. The tube appears to be quite stiff, though I couldn’t tell if it were a bit more flexible than the Vittoria tube I have.

I was most excited to see what they would be like on the road and after riding some local gravel roads and having gone on a longer trip I can see that the Supersonic’s are exceptional. I was surprised to see how well the tires ran given the section width of 25mm. The Supersonic’s rolled exceptionally well and gripped even in gravel and dirt. The center tread pattern was very smooth, with a tire pressure of about 85psi. The Supersonic’s were just a bit more flexible than the Vittoria tube and rolled without any flats.

The first run of the Gravel bike didn’t disappoint. I found no flats in about 4 hours of riding. The ride was smooth and the Supersonic’s feel very high quality and work well.
