Continental Grand Prix Supersonics are extremely light weight tires that might be interesting to use at time trials or criteriums. Supersonic 23mm tires weigh only 155g and that is so low that I thought it was worth to take a closer look on them. Light tires not only lower the overall weight but also improves cornering significantly (softer materials means better grip).
Why you should buy Continental GP Supersonic
The performance is absolutely world class. These tires are extremely fun to ride. When you corner with Supersonics you will feel an incredible good grip. I think that is the best thing about the Supersonics and the one that surprised me most. If you look at a formula 1 race you will see the same picture. Soft tires give the F1 pilots the best possible grip, but these tires have to be changed one or two times during the race.
Light weight components are always attractive. I have previously shown what difference additional weight can do on your finishing time during climbing. It’s great to know that you use light weight components, but it’s impossible to feel a weight saving of 120g. Still, you might very well make a significant difference on your performance.
Why you shouldn’t use Continental GP Supersonic all the time
It’s clear that extreme optimizing of weight and rolling resistance means, higher risk of punctures and shorter life time of tires. That is absolutely a serious reason to give it an extra thought before you mount Continental GP Supersonics. I think the supersonics can be ridden for app. 5-700km depending on road conditions and your body weight.
