Cervelo S-Series Ultegra Di2 Disc Road Bike 2021
With a stiff but comfortable carbon frameset that also has an aerodynamically tuned silhouette, the Cervelo S-Series Ultegra Di2 Disc Road Bike possesses a multifaceted character that is set to perform in sprints, up climbs or on solo dashes away from the pack.
The advanced carbon construction of the frameset is bolstered in critical areas to heighten pedalling stiffness and to grant precise handling while remaining lightweight. The resulting lively climbing sensation and nimble cornering are complemented by the aerodynamic efficiency that is donated by the sculpted frameset tube sections. Gear cables and brake hoses are entirely hidden inside the stem and frame to keep them out of the wind and to give a super-slick aesthetic.
Reserve wheels use their 50mm deep, aero-tuned carbon rims to carve through the air while remaining stable and controllable in crosswind riding scenarios. These wheels are also light and stiff to afford snappy accelerations and consistent climbing speeds. The Shimano Ultegra Di2 electronic configuration changes through its gear ratios with accuracy and dependability while confidence-inspiring stopping power is afforded, even in the wet, by the matching hydraulic disc brakes.
