these are the best inexpensive tires i have used. great looking tire with great grip. my only complaint is they lack some of the liveliness that a more expensive tire would give, but expected that. were tight getting on the rim had to use tire tool. overall great training, touring tire.
This is based on only the first 60 miles put on (700c x 28mm) Continental Ultra Sport III folding tires. Installation: pretty hard to do. After sweating to get the first one in place, I've decided to warm up the second one before trying to install. Warming up works! Tires are light, have low rolling resistance, and excellent grip. After 60 miles mostly on chip seal pavement with eventual dirt or cracked stretches, no flats. Time and mileage will tell more about tread wear. Up to now no wear sign. As for BTD service, swift and courteous.
I live and ride in a very hilly area, meaning I'm heavy on the back wheel when climbing and heavy on the front, when bombing down at over 40mph. This is my second set and the rare times they do slide they are stable and predictable. I wouldn't call them super long life, but I can imagine on the flats they would be a great long term tire.
