The only Vittoria's I have used are the 25mm Rubino ones that came on my Kinesis, took them off within weeks, put them on the Sirrus for a while before it was retired to the turbo and begrudgingly put the rear back on the Kinesis at the start of Jan (1550 miles ago). P'ture wise the tyre performs good (in fact I can't remember it ever p'turing on me) but grip wise its pretty poor, especially on the light Kinesis, even on drier roads. If you don't ride hard I'd say the Rubino is a good vfm tyre but if you do I'd stick away from them, that's the Rubino's mind but reading Kestevan's review the Zaffira aren't that much better. I've ordered
Mitch Krylion Carbon's but I think if I had a tighter budget I'd given
Mitch Lithion 2's a try.
