DERBY, England (VN) — Most of cycling’s aerodynamic glamor is in frame and wheel design. But Endura’s designers recognize that a rider’s body and clothing induces significant drag — up to 80 percent of a rider’s wind resistance......................

SST is only applied to the sleeves and flanks for a reason. These are two areas on the rider’s body where laminar separation — or the separation of air from a surface — can cause problems by creating a low-pressure pocket on the trailing edge of a shape. It’s the same issue that airfoil frame tube shapes address.

The silicone chevrons help reduce laminar separation by creating tiny vortices of air. Airflow then adheres to that surface longer and flows more smoothly around it. That means the air separates from the surface later, shrinking the drag-inducing low-pressure air pocket behind the rider.
