THIS Cervelo frame has outstanding aerodynamics – Airfoil shapes designed by Cervelo for bicycle speeds, not for airplanes. Features that work, no aero gimmicks that work on a TT bike but not on a road bike.
It is light but efficient, vertically compliant as the seatstays are as thin as on the R3 but rotated 90 degrees.

It has a perfect balance that is aero, light, stuff and comfortable. It has the Aero sloping toptube and a stealth aero headtube.
