Cervelo P Series 105 Race - 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.

Starting at the front, 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.

Moving on back, hiding in plain sight, is Cervelo’s first internal frame storage. This isn’t a burrito hauler, or a place for your spare layers: it’ll hold a tube, small multi-tool, and a couple CO2 canisters. Not only does it keep all your essentials out of the way until they’re needed, but it also frees up the popular back-of-the-saddle hydration mount option.

There have been a host of other updates to the P-Series, keeping it convincingly atop any triathlete’s wish list: increased wheel and tire clearance, reduced aerodynamic drag, and neater cable routing. It all adds up to the bike of choice for those looking to make the most of the time between T1 and T2.

Free Speed

The new P-Series frame is 5.9 grams faster than the outgoing one, but the added tire clearance makes room for the Reserve 52/63 wheels and 29mm Vittoria tires, which combine for a 30 grams or 3.5w savings vs the Reserve 50/Vittoria 28 combo.

Fuel For Fun

In addition to the all-new in-frame storage, we still ship every P-Series with the Smartpak 400, our top tube-mounted bento box, which makes fueling on the bike much simpler without sacrificing aerodynamics.

Fit for Speed

The P-Series is all about adapting to the athlete. Maximumstack increased to 53mm, and we include spacers to bring the basebar up that high. Fitting and positions are evolving, and P-Series offers the most flexibility in an incredibly fast package.
