What goes into aero design?

The S5’s sleek design borrows much from the P-Series, including the extended seat tube cutout. From the dropped down tube to the shielding seat stays, all frame shapes are designed to smooth airflow over the entire bike and rider. Even the bottle cage location has been rethought to make it the fastest frame with one bottle or two. Add BBright™ technology and you get the best of aero engineering with maximum control and stability.


Shielding Seat Stays Hiding the rear brake from the wind, not from the mechanic. Properly formed seat stays hide the brake and improve air flow over the calliper. Dropped Down tube Positioning the down tube perfectly saves drag on the system by taking into account the interaction between the front wheel and the frame. Partial Seat Tube Cutout A close-fitting curve in the seat tube partially hides the rear wheel improving aerodynamics with no weight penalty.
Shaped for Bottles Drinking is something that every rider needs to do. Taking this into account during design results in a faster overall package. Carbon Dropouts Tough, compression-molded dropouts save weight with no sacrifice in strength versus traditional metal dropouts. Future-Proof Cable Management Future-Proof Cable Management ensures your frame is compatible with all current and future derailleur and brake systems.
Extended Seat Tube Cutout A close-fitting curve in the seat tube trailing edge shields the leading edge and top of the rear wheel significantly improving aerodynamics. Evolved Steerer Design Different frame designs call for different steerer dimensions. We use the right dimension in the right application. BBright BBright increases system stiffness and reduces frame weight while allowing for a large range of crank compatibility in a modern press fit system.
Reduced-Friction BB Guide Smooth shifting that is easy to set up is no accident. Designing shifting requires a detailed approach. Small details have a huge impact. Aero Cable Management Cable paths are engineered, from the lever to the brake or derailleur, to reduce aerodynamic drag with no sacrifice in performance.
