| Introduction |
Thor Hushovd wins the first cobblestone race of the season on an S2
|
| |
|
“The workhorse frame for Cervélo TestTeam”
The S2 already has the reputation for being the ultimate pro bike; not surprising, given its long list of victories. But how about comfort? Truth be told, many frames with aero tubing lack in comfort. But at Cervélo, we have been designing aero bikes since our inception, so we have the most experience in building aero frames without sacrificing the traditional focal points of weight, stiffness, strength and comfort.
This may explain why only the Cervélo TestTeam used aero frames at the early season cobblestone races (including Thor Hushovd’s victory at the semi-Classic Omloop Het Nieuwsblad). While for some races the R-series may still be better, to know that the S2 (and the even more compliant S3) excel even on the cobblestones shows you can have all the usual characteristics of a great frame AND aerodynamics on top of it. That’s great news pros and non-pros alike.

| Upgrades from S1 |
| |
|
Lighter frame – The S1 is very competitive in weight (as a past winner of Liège-Bastogne-Liège, it has to be), the use of carbon fiber allows a further weight reduction. This makes the S2 very competitive in weight even compared to frames without an aero advantage.
Higher bottom bracket and torsional stiffness - While even the biggest pro riders have no complaints about the S1’s stiffness, the S2’s additional torsional stiffness make it track through switchbacks in fast descents even better.

| Feature-Benefit-Experience |
| |
|
The bike industry loves to talk about features (tube shapes, materials, etc). But a feature is useless without a benefit! Ask yourself, would you prefer a poorly engineered frame made of “Ultra High Modulus carbon” (a feature)? Or an intelligently engineered frame that uses the material to create something lighter, stiffer and stronger (real benefits)?
Even more than benefits, you want experiences. The aforementioned lightness & stiffness may be benefits, but what you really want is the experience of higher performance, through quicker acceleration and better climbing.
This is why we list not only features, but also the accompanying benefits and experiences. To recap:
Product Feature: “Which innovative shape, material or design solution was used on this frame?”
Technical Benefit: “What is the advantage of this shape, material or solution?”
Rider Experience: “How does this feature & benefit change my riding experience?” This usually involves experiencing higher performance or more comfort. Some features also offer an esthetic experience, and although we would never sacrifice performance or comfort for beauty, sometimes you can have it all.

| TrueAero® tubeset |
Lower aerodynamic resistance: TrueAero® tube shapes are designed for the lowest drag at bicycle speeds. |
Higher performance: Lower resistance means you need to generate fewer Watts for the same speed. |
| Optimized Smartwall for Carbon™ lay-up |
300 pieces of carbon positioned and spec’d to deliver stiffness, strength, light-weight and comfort resulting in a 25% lighter frame than the S1. By using unidirectional high-modulus carbon on the sides of the aerotubes, lateral stiffness is further optimized. |
Higher performance as lower weight and higher stiffness aides climbing, acceleration and sprinting. |
| Stealth aero headtube |
Narrowing the section between the bearings reduces the frontal area and thereby the aerodynamic resistance (which is linearly related to the frontal area). |
Higher performance as lower weight and higher stiffness aides climbing, acceleration and sprinting. |

Airplanes require different airfoils than bicycles. Sounds logical, but many companies are so proud to say their airfoils come from the National Advisory Committee on Aeronautics (NACA). So were we, 13 years ago.
But now, we design our own specific airfoils, and it has led to significant improvements. It’s one of the reasons why we spend weeks and weeks in the windtunnel each year, not hours (if any) as is customary in the industry.
When you have the most and the best engineers working on aerodynamic improvements and you give them more time to play in the windtunnel sand box than anybody else, you end up with faster bikes. Simple.

|
| Smartwall for Carbon™ |
| |
|
Patent-pending technology from our carbon materials and manufacturing group, Smartwall™ elaborates on the Squoval tubeshape. With the sides far away from the center plane more important, we concentrate more material there to increase the benefit.
Strips of High and Ultra-high modulus carbon stiffen the sides of the main tubes to resist lateral bending. These strips are feathered in to properly transfer the loads from the joints into these tubes.
Finally, we add Kevlar to the headtube/downtube area for industry-leading impact strength.

| Geometry |
The two seattube angles (73 & 76 degrees) can only be obtained with the optional two-position seatpost. With the single-position seatpost, only the 73 degree angle should be considered
|
| |
|
No custom Cervélo is needed even for the most demanding pros, that’s our conclusion after supporting hundreds of the world’s best athletes. The reason we don’t need customs where other bike companies do lies in our unique reach-based geometry. For an exhaustive explanation on why 6 Cervélo sizes fit more people than 12 “normal” sizes, check out our geometry tech presentation.
