Cervelo's S3 climbs, corners, and sprints like a pure road machine—only faster. It's meticulously crafted to reduce drag from head tube to chain stay, employing wide tubing, a rear wheel cutout, integrated seatpost, and an aero fork. Even the position of your water bottles reduces turbulence. Race-ready geometry and the fork's stiff tapered steerer bolster your cornering prowess, while thin seat stays reduce road chatter so you stay fresh for the final sprint. Stiff and fast Mavic Cosmic Elite wheels complement the S3’s already-impressive aero attributes. Smooth, accurate shifting is at your disposal thanks to Shimano Ultegra components and Rotor's 3DF crankset. Powerful Ultegra brakes, 3T's stiff bars and stem, and Cervelo's seamlessly integrated aero seat post round out this speed-hungry machine.
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.

After doing a lot of homework (and test rides), I decided to go for the Cervelo S3 due to the well-rounded nature of this bike. First thing I have to say is this bike is FAST. As advertised, the aerodynamics of the S3 is solid and from a pure riding standpoint it not only is easy to accelerate, but the S3 also seems to maintain high speeds very well on flats. This bike is also wicked fast on drops. Cornering is a breeze and it was also not as difficult to climb with the bike as some have suggested. From a climbing perspective, I don't see a huge differential between the S3 and my Cannondale SuperSix, which is a fine road bike as well. The geometry of the S3 is the same as the S5 but the bigger fork definitely adds to the stiffness and the thin seatposts are excellent. It dampens the road on rough surfaces and this bike handles poor pavement very well. The Ultegra 6800 is solid and shifting is smooth as you'd expect from a new Shimano groupset. The stock Mavic Cosmic Elite wheels are a tad heavy but they are pretty tough and are perfectly fine as training wheels. I plan on getting a set of Carbones in the future, but for now this is just fine as I don't feel these wheels are a huge detriment to my current needs (but eventually I will upgrade the wheels to get more out of this excellent frame). If you're in the market for a great all around aero bike performance with some of the perks of a top notch road bike, I strongly recommend the S3.
