Find yourself off the front with Cervelo's wind-defying S3. Its meticulously crafted aero frameset reduces drag from head tube to chainstay, employing wide tubing, a rear wheel cutout, an integrated seatpost, and an aero fork. Even the position of your water bottles reduces turbulence. Race-ready geometry and the fork's tapered steerer bolster your cornering prowess, while thin seatstays reduce road chatter so you stay fresh for the final sprint. Coupled with Rotor's 3DF crankset, Shimano's Ultegra Di2 drivetrain shifts with complete accuracy, requiring only the slightest touch of a finger. You also get Mavic's Cosmic Elite wheels, Ultegra brakes, 3T bars and stem, and Cervelo's seamlessly integrated aero seatpost. Slice through the wind and catapult out of the corners with Cervelo's S3.
The optimum steerer tube diameter must strike a balance of stiffness and energy absorption. Cervelo has found that 1 3/8-inches is ideal, providing enough added stiffness to ensure precise handling without being too rigid or uncomfortable.
Frames are but one component of an entire system. Cervelo considers your hydration needs as part of the aerodynamic equation. Two water bottles fit in the usual positions: one on the seat tube, one on the down tube. In the standard 2-bottle arrangement, the bottles fit together tightly with each other and the frame, reducing the gaps where turbulence can form for lower aerodynamic drag.
In addition, an extra bottle boss on the down tube creates a new lower position for a single bottle. Using the low position on the down tube saves 14 grams of aero drag, a reduction of about 1.4 watts, compared to a bottle in the usual position.
