P5

The P5 is Cervelo's no-compromise triathlon/TT flagship — the bike that has won multiple Ironman world titles and pushed the brand's reputation in long-course racing. After five years without major change, the 2025 generation was unveiled with a wholesale redesign: the new fastback seatstay shape reduces vertical stiffness by roughly 22% while keeping lateral stiffness for power transfer, the proprietary aerobar pads gained meaningful fore-aft adjustment and a much-wider fit window, and tyre clearance jumped to 34 mm. Engineered around a lowered basebar that drops CdA significantly, the new P5 also tunes the bike-plus-wheel system together — with Reserve's 77/88 wheelset and 29 mm Vittoria Corsa tyres Cervelo claims an extra 5 watts of system-level savings.
