Ryan Dwrote a review of Continental Gatorskin Tire - Clincher on July 13, 2018
Familiarity: I've put it through the wringer
These are my commuter tires and now I just bought a pair for my road bike. I've ridden over all the hazards of the road including glass and they just laugh at it. When the weather is nice and I want to go fast, I use the GP 4000 IIs. They aren't bomb proof, but they have a lower rolling resistance over the gatorskins. However, if you are going for big miles, the extra 9 watts of power needed for the gators might outweigh the concern over a puncture.
