Cervélo P5 Ultegra Di2 (2026)

The benchmark for TT & tri speed. The 2026 Cervélo P5 Ultegra Di2 combines Cervélo’s wind-cheating Bayonet P5 fork, fully hidden cabling and a size-matched cockpit with Shimano Ultegra Di2 12-speed. Dura-Ace R9180 TT brake levers and R9160 bar-end shifters keep shifts instant from the extensions, while a 4iiii GEN3+ dual-sided power meter dials in pacing. Deep Reserve 77/88 TA wheels on DT Swiss 240 hubs deliver race-day aero, and Vittoria Corsa Pro TLR 29 mm tyres balance speed with grip. Practical touches—thread-together BBright, rear hydration mount, P5 stem storage, Smartpak 400 top-tube bag and aero bottle/cage—make the P5 fast and easy to live with from T1 to T2. Gloss Black/Black or Red Hot.
