Cervélo P-Series 105 Triathlon Bike
The P-Series is the ultimate choice for athletes in search of speed, storage, value, and comfort. Engineered as a no-nonsense machine, it is designed to propel you from point A to B with unparalleled speed and efficiency. Serving as your perfect PR sidekick, the P-Series surpasses its predecessor, the P3, in both weight and aerodynamics, ensuring optimal performance on any course. Beyond its streamlined design, the P-Series offers practical features such as a 500mL aero bottle, 400mL of top tube storage, and an integrated rear hydration mount. The customizable cockpit and storage options allow you to tailor the bike to your unique needs, ensuring a personalized and efficient race experience.
When it comes to achieving maximum speed, the P-Series prioritizes aerodynamics to an unprecedented degree. Acknowledging that aero drag contributes up to 90% of overall rider resistance, the frame design and customized tube shapes of the P-Series are meticulously crafted to minimize drag while simultaneously enhancing stiffness, reducing weight, and maintaining UCI-legal standards. In addition to its aerodynamic prowess, the P-Series introduces Modular Storage, which integrates custom Cervélo parts and approved aftermarket accessories. This revolutionary feature allows riders to fully customize their storage needs, ensuring a secure and aerodynamic solution tailored precisely to individual preferences.
