For our newest AERO model, we were able to produce an aero frameset that is very light, combining the greatest aspects of what a road racing frameset can be. The aerodynamic efficiency is the result of our design realized with computational fluid dynamics. In keeping true to our design ethos of combining the best from a road and a TT bike, we keep the silhouette of the air sleek and uncluttered as the frame. We have applied Kamm tail truncated airfoils which mimic deeper airfoils yet remain within the UCI regulations and help ease the notoriously ill ride quality of pure airfoils. This method is frequently used in the car industry, to minimize the aerodynamic drag of the air and is quite notable on the cutaway seattube, which arcs around the rear wheel. Not to worry, there’s sufficient clearance to use a 25c tire in front and rear.
The top tube has a custom aero seatpost with the clamp sitting flush. The integrated seat clamp is neat enough, if no longer revolutionary (Wilier, Fondriest, and Scott use a similar design). Internally, however, there’s a wedge that expands inside the seat tube, which along with the clamp, represents a belt and braces approach to the challenge of securing a flattened seat pin. The internal cable routing not only gives a cleaner look, but is more aerodynamic. Because of internal sleeves, the internal cable routing is easy to set up.
The frame incorporates a tapered headtube and integrated aerodynamic “twin blade” fork that’s designed to aid airflow and reduce air turbulence (and, therefore, drag) that is wider than usual. The greater width is not only more effective in the wind but that it also provides greater stability and control. With a lowered down tube, the fork crown sits gracefully in the frame’s silhouette. The integration of fork crown and headtube is one of the more impressive features. The downtube also is shaped to reduce air turbulance and provide an aero, but smooth ride.
We seem to have succeeded in creating a frame which is exceptionally stiff with no discernible flex from that bottom bracket, whether sprinting hard or climbing out of the saddle. The frame’s stiffness means it reacts well to changes in pace and gradient. When you really turn on the power, the stiffer platform enhances the raw acceleration. It’s over long miles and rough road where the CFR7 really impresses. The aero road platform, industry wide, is no longer the ill-mannered beast it once was, but the CFR7 takes it to the next level. This aero road bike is smoother than many pure road racers and while big hits still make it through, they are not the vicious filling rattlers many aero bikes still communicate. The bike’s custom aero seat post and the lowered chain stays must allow plenty of seat cluster deflection when necessary. Aero gains with essentially zero sacrifice in ride quality!
The response at the pedals is magic, the confident handling at speed is perfection and the road feel is spot on, just right for long days at a rapid pace.
