Cervelo S5 Dura Ace Di2 Disc Road Bike 2021
With an advanced carbon construction, a design centred on aerodynamic performance and state of the art components, the Cervelo S5 Dura-Ace Di2 Disc Road Bike lays a strong claim to being the fastest bike available in today’s market.
The high grade of carbon utilised for the frameset construction is laid in a specific format to result in the stunning bottom bracket and head tube stiffness to ensure that every watt is translated from the rider into forward propulsion. Despite this high lateral rigidity, the sophisticated carbon lay up also guarantees comfort and keeps the overall weight to a minimum. The quest for speed is further satisfied by the TrueAero sculpted frame tube profiles, an innovative fork head tube shroud, the V-Stem and a custom handlebar that all work in unison to reduce aerodynamic drag tremendously.
ENVE SES 5.6 wheels lend their wind-cheating rim profiles to the build and are responsive and light. They are driven forward by the top of the range Dura-Ace Di2 electronic gear setup that ingrates a 4iiii Precision dual-sided power meter into its chainset to give the rider invaluable feedback when racing and training. The addition of a CeramicSpeed bottom bracket is a professional touch and lowers rotational friction markedly while the Dura-Ace hydraulic disc brake configuration stops with accuracy and power under any weather conditions.
