Hi, I have some All Black Foldable Vittoria Rubino PRO 23 x 700C Tires. These are about 220 Grams each. They are more durable then the ever popular Michelin Pro-Race modesl. A little less supple then the Michelins, :o but are a bit longer wearing and have greater puncture resistance. My impression is that I feel more confident on fast descents with these, but find that I like the cornering of Micelin tires a little better. But, heck, I don't want to go down, so I have become more consevative on twisties as of late. ;D :o The RUBINO PROS retail for $110.00 the pair, but of course, are sold for less from various folks on the NET. Get them direct from me now for just $27.00 each.
