2026 Cervelo S5 Frameset
Building your dream race bike? Love the thrills of testing your fitness and riding at your limits? The Cervelo S5 Road Frameset is the ideal base for creating your perfect training and race-winning setup. The front end and forks of the S5 have been 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. It's lighter too, with a weight saving of 124 grams, giving you some extra help on the climbs. The frame geometry is designed around 29mm tyres, ensuring you enjoy a smooth and comfortable ride on modern performance-focused tyres. While it’s faster and leaner, the S5 still delivers the precise handling, stability, and razor-sharp responsiveness that you'll love.
Cervelo HB19 Carbon one-piece cockpit
The distinctive V-shaped bar and stem remain from the previous generation, 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
