Cervelo P-Series Triathlon/Time Trial Frameset 2026 The all-new P-Series draws clear inspiration from Cervelo’s flagship P5, benefitting from the same racing experience, wind tunnel testing, and development that made it the fastest TT bike in the World Tour. Designed for triathlons of any distance, the P-Series adds versatile features to make it the ideal choice between T1 and T2. The bike uses a fork with a D-shaped steerer tube and round stem interface, allowing athletes to choose their preferred basebar and extensions, and make adjustments as fit needs evolve. Increased tyre clearance, reduced drag, clean cable routing, and Cervelo’s first internal frame storage make the new P-Series more adaptable than ever. Cervelo Free Speed The new P-Series frame is 5.9 grams faster than its predecessor. Combined with the added clearance for Reserve 52/63 wheels and 29mm Vittoria tyres, riders gain an additional saving of around 30 grams, or 3.5 watts, over the previous Reserve 50/Vittoria 28 set-up. P-Series In-Frame Storage For the first time, the P-Series features in-frame storage, designed to carry a spare tube, small multi-tool, and a CO2 canister. The hatch can be quickly removed with or without a bottle in place by simply flipping the lock and pulling. Fuel for the Run Every P-Series still comes with the Smartpak 400 top tube-mounted bento box, making on-bike fuelling simpler and more aerodynamic, so athletes can stay topped up for a stronger run. Cervelo P-Series Fit for Speed The P-Series prioritises adaptability. Maximum stack has increased to 53mm, and included spacers allow the basebar to be raised to match. With evolving fit needs and positions, the P-Series offers unmatched flexibility in an uncompromisingly fast package.
