I have used Continental Grand Prix 4000 tires on all my bikes since they were first released and I did not think a better road tire could be produced. When I saw that the Grand Prix 5000 was being released, I ordered a pair the same day. The new tire is incredible and has lived up the the claims of faster, more comfortable, and more grip. I am impressed with the improvements.
I needed to find a good quality tube for my hauling bike. After a few weeks of use on the roads, I not once had to break out the tire repair tools! ) (New rim tape also helps.) I did add some air but with weather expansion-contraction, that's normal. Very pleased.
I ride gravel trails with the grand kids and occasionally commute on debris laden deteriorating city streets with inattentive drivers. Good side wall protection is a must and thus have avoided many opportunities for punctures. Adjust the air pressure to the terrain 40 - 55 lbs. and ride with confidence. I have not made a direct comparison with comparable Compass tires but I think they are close in speed and comfort - on sale well worth the price. Had been using 32 mm Gatorskins and these are better for all weather traction, comfort and speed. The black edition actually improves the appearance of my beater VO campeur. To sum up, A tire that does its job very well.
Used on a street trials bike for multi surfaces. Has mostly been street yet it is an off road tire primarily for trails in all conditions. Have ridden skate parks, bmx track, logs, stones, jumps, and rails. Going tubeless this week and can't wait to continue the ride. My best surprise was black Friday after thanksgiving during a rainy wet rock ride. The tires stuck and hydraulic brakes helped but the surface was slippery. The tire has met all expectations with only a month in from weather, drifting soil, and street trails. They rule. I expect to repeat and grab the Race Kings.
