I am going to put some new rubber on my pride and joy. Ideally I am looking for something light with low rolling resistance. Would also like it if they were durable and lasted for a good few miles. A reasonable price would also help! Last year I settled with Continental GP4000S, was happy enough with them. I also have experience with Schwalbe Ultremo R1's, they did not last much over 1000 miles. This year I was also looking at Schwalbe Ultremo ZX's and Vredestein Fortezza Tricomp's. What do you think?
