Description:
The 2027 Cervélo P-Series 105 is an elite, aerodynamic carbon time trial and triathlon bike inspired by the flagship P5. It features a faster aerodynamic frame design, integrated internal frame storage, a reliable Shimano 105 12-speed mechanical groupset, and Vision TC60 i23 wheels. It is built for pure speed, making it a top choice for triathletes and time-trialists chasing personal bests from T1 to T2.
Designed For:
The Cervélo P-Series 105 is designed for pure speed, triathlons of any distance, and UCI-legal time trials. It targets riders wanting to optimize every second between transitions through maximum aerodynamic efficiency, flexible fit options, and integrated race-day storage.
Highlights:
The P-Series descends directly from greatness—sharing a striking resemblance and wind-tunnel-tested lineage with Cervélo’s flagship P5. It benefits from extensive aerodynamic testing while adding practical features designed specifically to make it the ultimate companion for triathletes and time-trialists.
The new P-Series frame is faster than its predecessor, while offering increased tire clearance and user-friendly adaptability. Using a fork with a D-shaped steerer tube and round stem interface, it lets riders customize their aero cockpit, basebars, and extensions to meet exact fit requirements.
New for this generation, the frame features integrated internal storage in the down tube built to securely hold an inner tube, small multi-tool, and a CO2 canister. Combined with the included Smartpak 400 top-tube bento box, fueling and carrying race essentials has never been more aerodynamic or streamlined.
The Vision TC60 i23 wheelset provides incredible speed, high inertia, and optimal efficiency on rolling and flat sections. Paired with wide Vittoria Corsa N.EXT TLR tires, the setup maximizes grip, comfort, and rolling efficiency.
