Pushing the boundaries of flat-out racing, the Cervelo S5 Ultegra Di2 Road Bike iterates on previous generations to strike an impressive balance of speed and comfort. With exceptionally crisp lines and no cable clutter, Cervelo is redefining aerodynamics. The frame is exceptionally stiff in the fork and rear end, and when paired with the smooth-rolling Ceramic Speed 24 bottom bracket it's sure to make the most of every watt. Powerful Shimano Ultegra hydraulic brakes deliver the high degree of modulation you need for late-braking corners or feathering the speed in hairy dashes for the line. The semi-compact front-gearing setup and 12-speed cassette encourage sprints over big hills. Carbon Reserve wheels deliver straight-lining speed and zippy acceleration under power. *Due to a high demand in the global supply chain and bike industry since the start of the pandemic, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be of equal or better spec level.
