Detailed Description

With victories from cobblestone Tour stages to mass sprints to the World Championships, the S3 is Thor Hushovd’s favorite bike. Aero road bikes seem to be a “trend” nowadays, but for Cervélo and its riders, they are the essence of what Cervelo's do. They offer the advantages of reduced drag while preserving everything else you expect in a good road bike. Not an easy balance to strike, but 15 years of experience doing that certainly helps. Characteristics: Reduced Aero drag to save enrgy A low geometry to put yourself in an aero position Proper road bike performance, because an aero focus shouldn't compromise lightnes, BB / Torsional stiffness and/or comfort. TECHNOLOGY Oversized Bottom Bracket Area - Big volume and fluent form aligns the carbon fibers with the complex loads in this area - This increases: Side-to-Side BB Stiffness (better power transfer) Torsional Stiffness (better handling) TrueAero Shapes - Long-tail airfoils with a 3:1 ratio or better create the lowest drag - Truncation can be useful, for example if flow interacts with another object. Smartwalll for Carbon - Carbon strength & stiffness depend on the size, shape, material & fiber direction of each of the 300+ pieces of carbon in a frame - Cervelo's Smartwall lay-ups are based on 15 years experience and the most advanced tools, including in-house developed optimization software - Smartwall also puts extra carbon on the sides (far from the center plane) to increase stiffness at little extra weight. S3 Aero Seatstays - Special TrueAero shape": Profile designed in the direction of the aeroflow (horizontal) Different shape on the inside than on the outside (to deal with the spinning wheel) Only 10mm wide for maximum compliance (within reason), minimal weight and frontal area Aero Chainstays - Used on S3 and P4 - TrueAero shapes in the direction of the Airflow - Especially effective in cross winds. Aero Headtube - The narrow section between the bearings reduces the frontal area and thereby the aero drag (which is linearly related to the frontal area) - Narrowing this area also improves the headtube's aspect ratio (same gusset length divided by a smaller width renders a higher ratio) to get closer to a 3:1 airfoil. Internal Cable Stops ICS3 - With ICS3, Cervelo continues to lead the industry in internal cables - No housing inside the frame gives crisper shifting and 200 grams less weight. - New stainless steel internals with replaceable Teflon liners further reduce the friction. - Integrated toptube adjuster allows on-the-fly fine-tuning. A first for internal cable systems.
