Cervelo P5 Shimano Ultegra Di2 12 Speed

P5 is a contre la montre catalyst. It’s made for one thing—helping you go as fast as possible between Point A and Point B.

As at home on the Big Island as it is in a race-critical time trial at the Tour de France, the P5 enables exceptional performances. The past decade of elite road racing has shown the importance of being able to deliver a strong time trial late in a Grand Tour, and the P5 was a key part of Team Jumbo-Visma’s Giro d’Italia and Tour de France wins in 2023.

On the new bike, we focused on creating a fast platform that could be made faster with the latest wheels and cutting-edge fit adaptations. There’s room for a 34mm tire on wide wheels, which improve aerodynamics and reduce rolling resistance. The basebar is lower to reduce CdA but possible stack has increased, and the extensions can now be adjusted between 0 and 30 degrees in five-millimeter increments. For triathletes, we include a variety of storage options, because half the battle is taking in sufficient calories to deliver a strong marathon. Also new on this bike? A size 61 to help all of our tall friends achieve a better fit.

SIMPLICITY & ADJUSTABILITY

The new one-piece front end (first pioneered on the S5) is simpler to assemble and adjust, and stack is now adjustable up to 40mm, while the basebar height drops by 10mm to minimize frontal area. The new riser increases tilt adjustability, 0 to 30 degrees, in 5-degree increments.

SPEED

The new P5 frame is about a watt faster aerodynamically than the previous model and has clearance for 34mm tires. That clearance means plenty of room for Reserve’s new 77/88 wheelset, and Vittoria’s 29mm tire. which saves about 4 watts over the previous Reserve/Vittoria pair for a total system savings of about 5 watts.

COMFORT & CONTROL

The new armrests and pads on the P5 are wider, taller, and thicker than before. It’s definitely more comfortable, but it’s also more confidence inspiring. More surface area here leads to better control, which means more time in the most aerodynamic position possible.

COMPLIANCE

The new fastback seat stay design reduces vertical stiffness by about 22% (while maintaining the lateral stiffness needed for power transfer). The TT position is unforgiving (to say the least), but the new P5 will help you roll into T2 a lot fresher.
