Cervélo P5X SRAM Red eTap
The draw: All out for aero
Cervélo designed this beast using 14,500 pictures taken during 70.3 and Ironman events in 2013 and 2014, a topology optimization program which tells designers where you actually need material to construct a bike, and wind tunnel testing, then designed it around storage. The front end uses a separate post that slides up or down to adjust the height of the arm rests and extensions, with 112mm of adjustment overall. With the lowest stack height of any bike by two centimeters (a size medium has a stack of 496mm), it is best suited for those who want to get low. There are three storage compartments, one up top and two on the frame, though the top and one frame compartment can be removed. Comfortable at full speed, the massive bottom bracket responds immediately to input, though its weight (22.7 pounds) means it takes a little while to get there. Over rough roads and train tracks, any flex in the mast was imperceptible. For better aerodynamics and braking, Cervélo chose TRP mechanical brakes (hydraulics to come later) with larger, 160mm rotors (others use 140mm). Traveling with the P5X is best done with the optional custom travel case ($850). Opting for the Ultegra Di2 package with Rotor cranks and HED Jet 6 Plus front and Jet 9 Plus rear wheels brings the price down to a still jaw-dropping $11,000.
