Cervelo P3 Frameset

With the increasing prevalence of electronic controls, the permanently bonded-in ICS3 guide tubes are no longer required for proper shifting performance. Leaving them out simplifies electronic installation and saves weight.

Cervelo engineered BBstop to accommodate all shifting options (mechanical and electronic) in a single design. BBstop incorporates a stop in their Single-Bend bottom bracket guide, permitting the use of cable housing through the down tube. This stop prevents housing shift (fore-and-aft) and fixes the axial position of the housing where it enters and exits the frame for consistent bend radii.

Each individual cable gets its own individual curve. One curve in one plane; the cable bends only around the bottom bracket, not side to side. By removing twists and bends from the cable path, friction load is removed, ensuring crisp effortless shifting in all conditions. 

Dropping the down tube “hides” it in dirty air, reducing the high pressure normally found on the down tube’s leading edge, and eliminating the low pressure air that normally pulls rearward on the fork crown.

The P3 offers multiple gear-carrying options, each one specifically positioned to minimize aero drag so you’re always ready to race. It's designed for a frame-mounted battery on the down tube.

It also feature a horizontal, standard two-bolt bottle cage between the arms on the aerobar, which Cervelo has found to be, by far, the most aero position. Two mounting bolts behind the stem add carrying capacity.
