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 options for carrying your gear, 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 more gear-carrying options.
