Not to hijack this thread, but has anyone figured out the best 700c x 35cm on up tire for rando? I just started riding my new rando bike and have been using the Vittoria Rando Hypers in 35cm. I have about 1500 miles on them so far and no flats, but the bike in general is definitely slower (overall average speed) than my Colnago C50 with 24cm tubular tires. My rando bike is almost double the weight of my colnago however.
