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.

This Dura-Ace Di2 build leaves little to be desired, with Shimano’s top-tier electronic drivetrain system that features a low-profile front derailleur and a 12-speed cassette. Dura-Ace disc brakes are paired with 160mm rotors for reliable stopping power, while the Ceramic Speed 24 bottom bracket ensures an ultra-smooth pedal stroke. Carbon Reserve wheels are stiff for acceleration and straight-lining speed, plus they accommodate tubeless tire setups.

*Due to unprecedented demand in the global supply chain and the bike industry over the last 18 months, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be minor. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.
