I haven’t yet tried the Vittoria Randonneur Pros or Hypers, but I have tried the Conti Sport Contact, in both 26x1.6” and 700x37c, and they seem to be very fast and are supposed to be very puncture resistant. I haven’t had any flats yet, but I have only been running them for a few months. As a certified Clydesdale who rides a lot, they are doing well for me. I ride pavement and don’t get off road too much.
I am very pleased with the progress bike tires have made over the last 40 yrs that I have been riding derailleur bikes. The best tires are at least as fast as the older tires, but the durability and resistance to punctures has dramatically improved. In the tests I have conducted with my own bikes the Conti Top Touring 2000 700x37c tires are equally as fast as the Conti Sport Contact 700x37c, but the TT2K weren’t particularly puncture resistant, and the Sport Contact is very puncture resistant. In 26”, the 26x1.75” Conti TT2K is a nice tire, but not particularly fast, while the Sport Contact 26x1.6” is just as fast as the 700x37c. I have found many 26” tires very disappointing in performance and more suited for use as tractor tires and was very pleased to find the Sport Contact. I would like to try the Vittoria Rando Pros and Hypers to see if they are as good or perhaps better. I did try Panaracer Pasela TG and found them reasonably fast, but somewhat fragile, particularly in the rain. Overall I was disappointed in them.
