I've been riding on Vittoria Rubino Pro's for years on my road, commuter, and track bikes. Gave these G Speeds a try on my road bike and was amazed by how much smoother the ride was, and better control around tightfast corners.
It feels like they have less rolling resistance than the old Pro II's, but I don't have any personal numbers or testing to back that up, BikeRollingResistance.com seems to score them high however httpwww.bicyclerollingresistance.comroad-bike-reviews?bvittoria&maxweight401&max23&min7&minpr7
So far no flats in the 9 months I've had them. Ridden mostly on roadtrack 2-3x a week and 2x races.
after years on using conti's ( all models) i decided to try something new that nobody in my group uses, so i bought a set of these. keep in mind the group that i ride with are huge fans of anything Specialized, so i am always the odd man out with my 2015 Kestrel Legend. This past weekend our ride was a 142 mile loop in Southern Cali. Long story short, i torched 19 of the 21 MFers in the bunch, 4 had blowouts with their Specialized Turbo Cottons (HA) and the others just bonked (HA HA). I can honestly say it was the Rubinos - fast cornering, ground hugging, Specialized smashing Rubino Pro Speed G. The G stands for Get the F outta here! the only thing i didn't like about the tire is the price, i would like to get a couple more as spares. but my wife says No wait until they go on sale or find a coupon...she is not a cyclist so she doesn't understand.
