First time trying these on a road bike, in 28c. So far after around 500 miles of riding, I'm happy with the performance and durability. It works well on paved roads, rolls well, and are quite OK on some rougher surfaces as well. They look pretty good too!
Id read early reviews saying this was a good ride, but also complaints that it didnt hold air and was hard to mount. I mounted them on DT Swiss Spline 24 rims using Stanss Notubes rim tape and 3 oz. of Stans standard sealant and have had zero problems, and no pressure loss, even over a two week layoff for that bike. The ride and handling have exceeded my expectations. A great all-road tire.
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.
