The Cervelo P4 Carbon Frame 2009 is the eagerly anticipated successor to the current time trial standard, the Cervlo P3. As the P3 is still the fastest bike available three years after its introduction, it is clear that creating its successor was no easy task. After millions in research & development and over two months of intensive testing at the San Diego Low Speed Wind Tunnel, the P4 is the fastest bike ever in the wind tunnel, including both UCI-legal and illegal bikes.

The P4 is the biggest leap we have ever made in aero bike technology,� said Phil White, co-founder of Cervlo. The P series has evolved significantly over the last decade, making it a real challenge to keep finding improvements. With the P4, the mandate was to make it significantly faster than the P3 while achieving equivalent or better performance relative to stiffness, power transmission, low weight and comfort. Im pleased to report that we have met those goals.�

The strengths of the P4 are found in its many fine details, some of which are quite visible but others are difficult to detect at first glance. The key to the performance of the P4 lies in the frameset integrated design. This System Engineering approach, which considers the frame, components, wheels, hydration and the rider together, generates substantially reduced drag values in virtual (CFD) and physical wind tunnel testing.
