P-Series 105 Di2 Triathlon Bike 2026

Cervelo P-Series 105 Di2 Triathlon Bike

Inspired by the top-tier P5 TT bike, the P-Series 105 Di2 Triathlon Bike benefits from the same research and development, both in the wind tunnel and real-world testing, to make it a fast bike, but the addition of triathlon-focused features makes it a class-leading choice for aspiring and experienced triathletes alike. 

Whether your fit evolves or you're chasing the most efficient aero setup, the P-Series is built to accommodate it. Profile Design's Wing Super Sonic cockpit assembly and aero-shaped extensions, and refined cable routing ensure it's a machine designed to reduce drag without compromising flexibility. With its D-shaped steerer and round stem interface, this bike gives the freedom to run your preferred basebar and extensions, ideal for dialling in a fit tailored to your unique riding position.

Beyond its aerodynamic efficiency, the P-Series is engineered with triathlon in mind, right down to the smallest details. Increased tyre clearance allows for improved comfort and speed across varied surfaces, while Cervelo’s internal frame storage keeps essentials like a tube, multi-tool, and CO₂ canister tucked neatly inside the down tube. Access is quick and simple, even with a bottle in place, thanks to an intuitive locking hatch. Add in the Smartpak 400 top tube bento box, and you’ve got everything you need to fuel on the move, without disrupting airflow. The P-Series 105 Di2 isn’t just fast; it’s smart, adaptable, and built for triathletes who want to focus on performance without distraction.
