Cervélo P-Series 105 Di2 12S 2025

Take one look at the all-new P-Series, and you’ll notice a striking resemblance to our flagship TT bike, the P5. P-Series benefits from all the racing, wind tunnel time, and testing required to make the P5 the fastest TT bike in the World Tour, but adds a couple features that make it a perfect companion for a triathlon of any distance.

P-Series uses a fork with a D-shaped steerer tube and round stem interface. This means you can use whichever basebar and extensions you prefer, and make changes if your fit or preference changes. It’s also significantly more adaptable if you have very specific fit requirements.

Increased wheel and tire clearance, reduced aerodynamic drag, neater cable routing, and Cervelo’s first internal frame storage all add up to create the bike of choice for those looking to make the most of the time between T1 and T2.
