I never had much of a problem with Vittoria Zaffiros on my old Alex rims or Vittoria Open Corsa Evo Cx tires on 1980's vintage Mavics, but I had a major hassle putting a new Bonty Race Lite on a Bonty wheel. Two days, lots of soap, water, and cursing....and two tubes. You would think that it would have been easier considering that they are supposedly made for each other.tonyzackery said:I have to second (or third, can't remember) the mention that Vittorias are THE most difficult tires to mount/dismount. I don't buy them at all (even though I like the ride of them) because of this major hassle...
