Continental Grand Prix 4-Season with Vectran

I use the Grand Prix 4-Season on both my road racing bike and my commute bike, it handles well, and offers more puncture protection than a race tire. These are great tires, rain or shine, which is especially good for those long winter months (here in Portland, OR, anyway). If you find yourself faced with snow in winter, a studded winter tire is more up your alley.

Bottom line, this tire handles nearly as well in rain as it does on dry ground. It's a great purchase for anyone who rides in all conditions, and wants a durable tire that feels good.

I put a 25mm GP 4-Season on my back wheel every Fall. For almost daily rides in Portland's West Hills, (3040 miles, 4000ft climbingdescending), these are the best balance of wet handling and durability I know. They are a bit pricey, but last as long as Gatorskins and feel a lot better.

Use the tire on a cross bike and it provides three season protection training on dirt roads (28mm). Without the knob hum of cross tires, square wear and the squirmy corners on tarmac. Speeds and spin up is respectable for the weight and durability aka mileage. If you can find them on sale they are a great buy, if not a little pricey. Ride safe.

I ride about 20 miles round trip, from deep in Brooklyn to Manhattan 5 days a weekMaybe it's because i was riding on Armadillos before, but i love these tires so far. I have only ridden about 200 miles so far, so i can't comment on how long they'll last but here's what i do know

1. they grip in all conditions - dry crud, slick light rainy streets after a dry period, and torrential downpours. my armadillos felt unsafe and i worried about taking corners too fast, i don't worry at all with these

2. they're soft, comfortable, but i don't feel much resistance (i use 25's at 110psi in the back and 100psi up front)

3. in two weeks the armadillos punctured 3 times. because they're so hard, they seem to hold onto little bits of glass, it gets rolled in, and eventually gets through. no problems with these and NYC is not what i would call clean or smooth.

4. my average mph has increased from about 14 mph to 15mph per ride

5. climbing is easier (they feel light to me) and i don't lose speed from resistance going downhill.

i got them at a discount, but i will be buying these again, full price or not.
