Cervelo P5 Ultgera D2 Triathlon Bike 2025
Achieve Unmatched Speed
The P5 is engineered with a single goal: to maximize speed between Point A and Point B. With 30 years of aerodynamic expertise, elite triathlete feedback, and insights from Tour de France champions, the P5 is the epitome of speed, adjustability, and comfort.
State-of-the-Art Aerodynamics
Harnessing extensive CFD simulations and 3D-printed prototypes, the new P5 is approximately 5 watts faster than its predecessor. This improvement is due to meticulous design and advanced wheel integration.
Designed for Wider, Faster Wheels
The P5 frame supports wider wheels, such as the Reserve 77/88 with 29mm tires, which reduce rolling resistance and boost aerodynamic efficiency. This setup not only increases speed but also offers a smoother ride.
Innovative Front End Design
Inspired by the S5, the P5’s one-piece front end is easy to assemble and adjust. The stack is adjustable up to 40mm, and the basebar height drops by 10mm to reduce frontal area. The new riser provides tilt adjustability from 0 to 30 degrees in 5-degree increments, accommodating individual rider preferences.
Aerodynamic Frame Excellence
The P5 frame is aerodynamically superior, saving an additional watt compared to the previous model. It accommodates 34mm tires, perfectly fitting the Reserve 77/88 wheelset and Vittoria’s 29mm tires, achieving a total system savings of about 5 watts.
Enhanced Comfort and Control
The new armrests and pads are wider, taller, and thicker, significantly improving comfort and control. This design allows for better aerodynamics by enabling you to maintain the most efficient riding position for longer durations.
Optimized Stiffness for a Smoother Ride
The new fastback seat stay design reduces vertical stiffness by about 22% while maintaining the necessary lateral stiffness for effective power transfer. This results in a more comfortable ride, helping you reach T2 fresher and ready to perform.
