'12 Cervelo

Cervelo’s S5 is revolutionary even for a company synonymous with the word. It begins with a carbon layup that’s tuned to optimize stiffness laterally and torsionally, plus shave every gram possible. Then, Cervelo’s aero genius hits high gear with a dropped down tube and an extended rear wheel cutout to smooth the transition of air from the front to rear wheel with nary a hiccup. The wind-cheating wizardry continues with an hourglass head tube, internal cable routing with top-tube entry and seatstays that shield the rear brake from turbulence to complete an ultra-trick frameset that screams towards the finish line with awesome efficiency and the maximum aero advantage. Its built for action, too, with SRAM's Rival components that shift and brake with precision, a race-worthy 3T bar and stem and speedy Fulcrum wheels with choice Vittoria tires.
