THE SELL: Race-winning design with only moderate sticker shock.
THE TEST: The most noticeable difference between the Paris and Pinarello's Dogma, one of the decade's most ballyhooed bikes? The Paris is half the price. You still get the asymmetric design (see below); the trade-off is that the Paris is made with slightly lower-grade carbon and a bit less shaping, especially in the chainstays—differences that add up to slightly more flex. But that extra give, compounded by the springlike compliance of the fork, is a good thing for most riders, who will appreciate the added suppleness.
THE VERDICT: Easily the most lust-inspiring bike in our test. 15.9 lbs (56); pinarellousa.com
Calculating that the forces exerted on a frame vary from side to side—they're greater on the drivetrain side than on the opposite—Pinarello built an asymmetrical frame: the right half of the fork, headset, chainstays, and seatstays have all been reinforced.
