Producing the ultimate in aerodynamic advantage, Smart Aero Technology has teamed up with ENVE to bring you the pinnacle of wheel design. With a history in Formula One racing, Smart have extensive knowledge and understanding of aerodynamic principles, theory and most importantly application. Based on the doorstep of Mercedes GP Petronas Formula One HQ in Brackley, UK the world of speed and all its facilities is at Smart’s fingertips.
However there is more to Smart than just a design element. The group’s biomechanical history has led to the natural progression into high-performance cycling. The necessary skill, knowledge and passion for high performance cycling componentry have found its perfect partner in ENVE.
There is no shortcut to perfection. It must be tried and tested, over and over, before the ultimate is achieved. That’s why the 4.5s were created from the beginning with in-frame development and then blended with proven aerodynamics. This resulted in optimised stability, lightweight, stiffness and durability, a truly revolutionary wheel design.
The Smart ENVE System optimizes the interface between the frame surfaces and the wheels, creating an integrated system. The front and rear wheels interact differently with the air and the rest of the bicycle. Rim shapes are optimized to allow airflow to stay attached at higher yaw angles, thus reducing drag and improving ride performance.
• The front wheel is wider and shallower to improve stability and reduce drag in any wind condition.
• The rear wheel is deeper to reduce drag where stability is less affected.
• Wheels were tested on multiple frame designs in order to produce the maximum drag reduction. The result is a wheel system, which handles predictably, and displays superior drag results when installed in multiple bicycle frame designs.
Steering feedback in variable conditions needs to be predictable to have total handling confidence. Less predictable wheels have a non-linear steering response, resulting in erratic and unpredictable handling in unsteady conditions. The shape of the Smart ENVE System rim is optimized to ensure even and predictable airflow attachment. What the rider experiences is a balanced build up of side force as the angle of crosswind changes. This allows the rider to accurately predict the handling mannerisms of the wheel and avoid dangerous over correction cycles.
• The focus on steering stability resulted in improved handling and confidence in varying crosswinds.
• Therefore, the wheel shape was optimized to produce a predictable and linear response.
• The target stability gradient was 1.0.
