Cervélo P5 Disc 2021 Simply. Better. A bike focused entirely on one thing: your performance. We applied years of experience in engineering the fastest aero bikes and real-world testing with our pro athletes. The result is a bike which pushes the boundaries in every way. Ideal For Time Trial (UCI-Legal), Triathlons Weight. Our engineers dedicated countless hours to testing and data crunching to make the P5 not only stiffer and more aero, but lighter as well. A lighter bike accelerates faster and climbs better to give you every possible advantage on the road. Aerodynamics. The legendary aerodynamics of the P5 are fine-tuned to create an aero system that is stiffer and lighter than ever before. Its frame shapes, handlebar and fit positions, and design features work together to reduce drag and enhance your efficiency. Stiffness. We refined the stiffness of key points of the frame to create a bike which corners better and transfers power more smoothly. You will feel it from your first pedal stroke: a stiff response that inspires you to pedal harder and go faster.
