Cervelo S5 Ultegra Di2 Disc Road Bike 2021
With a wind-cheating silhouette, advanced grade frameset materials and innovative construction, the Cervelo S5 Ultegra Di2 Disc Road Bike is one of the quickest options available when animating vicious sprints, surging on lone breaks or thundering along in the local chaingang.
With its advanced carbon construction and aerodynamically sculpted tube profiles, the frameset of the S5 is laterally stiff, comfortable and incredibly aerodynamic. The innovative V-stem and svelte handlebars combine with the fork’s head tube shroud to lower drag further. Increased comfort and lower rolling resistance can be experienced thanks to the frameset-to-tyre clearance for up to 28mm wide rubber.
The carbon rims of the Reserve 50mm wheelset use their sophisticated profiles to slip through the air with heightened stability, and these are driven by the accurate and reliable Shimano Ultegra Di2 electronic gear configuration. The chainset receives a professional touch by way of an integrated power meter, and this allows the rider to track their performance in races and key training sessions. This chainset spins with significantly reduced friction thanks to the CeramicSpeed bottom bracket. Shimano Ultegra hydraulic disc brakes complete the build by donating their modulated stopping power to any weather conditions.
