Cervélo P Ultegra DI2 Deep Dahlia 2025 - Time Trial & Triathlon Bike

The 2025 Cervélo P Ultegra DI2 Deep Dahlia from the P-Series range builds on the legacy of the renowned P5, with an optimized design and technical features perfect for triathlon events of all distances. This bike benefits from all the experience of high-level racing, wind tunnel testing, and rigorous adjustments that have made the P5 a must-have on the World Tour. The P-Series is a more accessible version, offering greater customization and adaptability, while maintaining exceptional aerodynamics and high-end performance.

Aerodynamics and Adaptability

The P-Series adopts a fork with a D-shaped steerer tube and a standard round stem, allowing for great flexibility in terms of fit. You can choose the extensions and basebar you prefer and easily change them if your needs or preferences change. The bike is also designed to be more adaptable for athletes with specific fit requirements.

Integrated frame storage

The P-Series incorporates an in-frame storage system designed to accommodate an inner tube, a small multi-tool, and CO2 cartridges. This storage system is easily accessible thanks to a removable hatch, which can be opened with or without a bottle in place. Simply flip the lock and pull for quick and convenient access while racing.

Convenient refueling

In addition to internal storage, every P-Series bike comes with the Smartpak 400, a top-tube-mounted bento box. This storage system allows you to carry your supplies without sacrificing aerodynamics, simplifying fuel stops during the ride.

An even faster position

The P-Series has been designed to fit each athlete's anatomy. The stack height has been increased to 53 mm, and spacers are included to allow for a perfect basebar fit. With these adjustments, the P-Series offers even more flexibility while maintaining an optimal position for performance.

Aerodynamic improvements

The P-Series frame is 5.9 grams faster in aero drag than its predecessor, while also offering additional tire clearance. The bike is compatible with Reserve 52/63 wheels and 29mm Vittoria tires, offering a 3.5-watt drag reduction over the old setup.
