Cervelo S5 Red AXS Road Bike 2027

Cervelo's race-ready weapon, the S5, has been re-engineered, making their fastest bike even faster. The Cervelo S5 Red AXS Road Bike builds upon the legacy of the race-winning S5, and sees the front end and forks redesigned to feature deeper chord profiles, boosting aerodynamic efficiency. An updated one-piece stem and bars create smoother airflow, while the sleek integration of asymmetric seat tube and rear wheel profiles has also led to aero gains. The result?  This latest iteration of S5 is some 6 watts faster than its predecessor, keeping some extra watts ready for launching a race-winning break or a final kick for the finish line.

Not just faster, it's lighter too, with a weight saving of 124 grams, giving you some extra help on steep pitches and steady high-speed climbs. While it’s faster and leaner, the S5 still delivers the precise handling, stability, and razor-sharp responsiveness that riders love. This is the S5, reimagined for those who love the thrills and challenges of riding at speed.

Cervelo x Reserve 57/64 Turbulent Aero

Co-developed by Cervelo and Reserve, the 57/64 Turbulent Aero wheelset has been tuned to work perfectly with this latest iteration of the S5 frame and forks. The asymmetry of the rear wheel matches the seat tube, ensuring smooth and efficient airflow over both. Meanwhile, the added depth of the front rim helps smooth airflow over the wheel in high yaw scenarios. Some 3 watts faster than its predecessor wheelset, the 57/64 still tips the scales at the same weight. 

Cervelo HB19 Carbon one-piece cockpit

The distinctive V-shaped bar and stem remain, but it's now a one-piece setup. The “Plus-Four” concept gives a handlebar design where the width at the hoods is 4cm narrower than at the drops - for example, 38cm at the hoods and 42cm at the drops. This innovative setup promotes a more aerodynamic riding position when your hands are on the hoods, while still offering enhanced control and stability in the drops for sprinting and descending. All handlebar sizes comply fully with UCI regulations, including the most recent updates
