Designed using formula 1-level cfd software & proven in the wind tunnel, the cervélo p 5 has more elite-level victories since its launch than any other triathlon bike, including frederik van lierde’s 2013 ironman world championship, & mary beth ellis & jodie swallow’s 2015 & 2016 itu long distance triathlon world championships. It also shines in time trials: ryder hesjedal clinched the gc at the 2012 giro d’italia on a p 5. This asymmetrical 79mm bottom-bracket standard yields stiffer & lighter frames & crank systems. Reduces drag by treating the front wheel & frame as one aerodynamic shape. Ensures your frame is compatible with all current & future derailleur & brake systems. The fork steerer’s diameter has a noticeable effect on a bike’s handling. Evolved steerer design applies the diameters & taper designs that best suit each model. A close-fitting curve in the seat-tube’s trailing edge significantly improves aerodynamics by shielding the leading edge & top of the rear wheel. Hide the rear brake callipers from the wind, not from the mechanic.
