Cervelo S5 Dura-Ace Di2 Road Bike

Whether we want to get the most out of our training miles or have a crack at the local race series, the S5 Dura-Ace Di2 Road Bike is among our top picks for the job. Cervelo designed this bike with aerodynamics at its core, with a cable-integrated stem that reduces drag and clutter for maximum efficiency. The carbon frame features added stiffness in the head tube and bottom bracket to ensure our energy transmits directly to the rear wheel with as little flex as possible.
