2009 Cervelo P4 Bicycle

The P4 is the eagerly anticipated successor to the current time trial standard, the Cerv??lo 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.
