Continental Grand Prix Supersonic w/ Black Chili

The fastest clincher in the world? Yeah, maybe so! With some concessions made in the puncture protection and durability departments, Conti has made this tire that really feels more like it's gliding that rolling. Sound too risky? Consider a Supersonic front with a Triathlon rear which is similar to the Supersonic, only with a Vectran puncture layer.

Used for club rides and all the riding I do. I always carry a spare in case of terminal failure which can happen with any tire , otherwise I think they are sweet. Great climbing clincher.

I weighed about 210 pounds when I rode my last set of these tires. I finally replaced them after riding them, would you believe 5,010 miles. One of the tires still has about 25% of the tread left on it as indicated by the wear marks that Continental uses to qauge the amount of rubber left on the tire. I now weigh about 195 pounds & expect to get even more miles from my current set.

Bought 1 of these tires at the beginning of last years race season. Decided to only use it on the front since I had worries about durability and it's light weight. Ended up using it even on training rides, to the tune of about 3000 miles and only had one flat. I'm confident enough in this tire to now also try one on the back as well for this season. I expect I will probably burn through 2 or more on the back though.

Bought these to replace the Stock Tires on my Trek, Got 640mi on them before the rear developed a bad spot under breaking. The Front is Still Good, will replace the rear and ride happy. Paired with a Michelin A1 tube and its a very fast combo.

Being a big Conti fan I looked forward to using these on the group ride. On my second ride my front sidewalls just blew apart while desending Trinity Grade in Sonoma. It was ugly.

These are junk, stay away from them and stick with the 4000s, the moderate weight improvement comes at the sacrifice of no durability, no puncture protection and no road life. For me these were literally two ride tires.
