Product | The new V4Rs has been designed starting from the direct inputs of the professional riders of UAE Teams. The evolution touched all the areas of the performance: Aerodynamics. Weight. Real Dynamic Stiffness. Sizing and geometry. Design robustness and maintenance. All the new parts and components followed the same strict validation procedure: Concept and Design Prototype phase Internal testing and design selection Complete system validation in racing conditions This final step is what really makes the difference, all the sub-systems come together to deliver the final behaviour of the bicycle, and its final performance is never the sum of the performance of each component (in engineers' language, there is no superimposition of effects principle). Therefore, despite all the innovative testing methodologies and validation, the best way to check that the improvements are consistent and not simply the result of a different trade-off position, is to take the whole system to performance limits (i.e. race conditions) and collect data and feedback. |
