Cervelo 2025 P5 Ultegra DI2 Bike

It might look similar, but there are a lot of changes!
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 base bar height drops by 10mm to minimize frontal area. The new riser increases tilt adjustability, 0 to 30 degrees, in 5-degree increments.
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.
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.
The new fastback seat stay design reduces vertical stiffness by about 22% (while maintaining the lateral stiffness needed for power transfer).
