Continental Grand Prix 4-Season with Vectran

It's packed with features! The Vectran is tops for preventing flats without ruining your road feel. The Duraskin helps prevent sidewall cuts. The extra soft rubber compound makes the tire grip exceptionally in bad weather. ...and all this without weighing a ton or feeling like a training tire. It's great! But somebody's got to pick up the tab, and it's a bit pricey for a training tire. If you have the means, I highly recommend picking one up.

I have been riding these tires for almost 2 full seasons, and have put about 3500 - 4000 miles on them so far. I had a blow out of the tire after apparently hitting something sharp. This is the first flat I have had in all of this time riding in New England. They have been durable, and flat resistant till now, so I will buy another pair of Contis to replace these. The rear tire was ridden last winter on my trainer, and lost it's roundness looks kind of squared off in profile, but it has not affected either ridability or durability.

I live in Puerto Rico. Flat roads hardly exist here, mostly hills, steep hills or very steep hills. Once you make it to the top your faced with a steep down hill leading to curvy turns. These tires grip well on those turns and ride through small broken glass debris with no problems. The down side to them is that they arent too attractive. But Ill gladly sacrifice this minor inconvenience for safety and durability. It feels great to complete a training route without having to stop to fix a flat, or worse, stopping because the side wall of the tire was slashed. I recommend them to any one who spend too much time fixing flats and not enough time training .

These tires are a bit pricey but they hug the wet slick roads like fly on flypaper. Ran over some keawe Hawaiian Mesquite and no flats. Had Gatorskins for many years and thought they were the best puncture resistant tires out there but these beat them hands down. With the Gatorskins though, it slipped a little when the raods were damp. A bit tight that I have to muscle them onto my DT Swiss R1.1 rims.

It does have great wet traction, is pretty round, is flat proof, but rides slow and feels dead for its cost. Maybe the point is that it is for bad weather, but then there are wider tires that are better. Its not bad, but I am not impressed except that it is indeed tough. Conti just doesn't seem to have a nice riding tire. Just opinion.

Tandem mfrs put this on their race tandems, so it goes on our wannabe race tandem. It is a very light tire for what you get. We are on our second set of 28c's, and only one flat at about 28mph on the front. Enough sidewall to roll good while flat too...

I swear by this tire, used it in Alaska for the Fireweed 400 mile race, Adirondack 540 mile race, Furnace Creek 508 mile race across Death Valley and Mohave, 24 hour races in Florida. Race Across America Solo, all races included dry, wet, ice, snow, wind, gravel, very rough roads across Kansas and Missouri.

Not to mention all of the multi-century training days for preparation for all of these races.

These tires are FLAWLESS, very easy to handle, mount and change. Great for steep climbs in wet conditions, really holds the road with almost no slipping.

These tires are my first choice, and I am not sponsored by Continental!
