The 3D woven stretch fabric used on the shoulders has a dimpled fabric structure, whilst the back panel features a linear airflow construction, created together to improve aerodynamic performance by reducing a cyclist’s drag. Getting fitted on a bike may seem like a one-and-done proposition, but it’s not. Cannondale confirms that the 45mm wheel would further reduce drag, but the 35mm spec on this bike makes for a more affordable price. The guys behind the SpeedX Leopard know that, so they built a performance-focused aero road bike with a bike computer fully integrated into it. An Affordable Power Meter and Aero-Drag Sensor.
