Cervélo P-Series 105 12S Race 2026

One look at the all-new P-Series and you'll immediately see the striking resemblance to our flagship TT bike, the P5. The P-Series benefits from all the racing experience, wind tunnel testing, and other tests that went into making the P5 the fastest TT bike in the World Tour, but adds a number of features that make it the perfect companion for triathlons of any distance.

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

More wheel and tire clearance, less aerodynamic drag, cleaner cable routing, and Cervelo's first internal frame storage make this bike the ideal choice for those who want to get the most out of the time between T1 and T2.
