Cervelo S5 Frameset TVLAB 2026

The Cervélo S5 Frameset TVLAB 2026 was developed for riders who count every watt, whether in a sprint, a fast local lap, or a long race. This frameset forms the basis for a highly efficient aero road bike and follows the same lines as the TVLAB replicas from the professional peloton. It is intended for cyclists looking for a sleek and purposeful platform to build their own top-tier setup.

Cervélo has re-optimized the front of the frame, with modified fork legs, a refined head tube, and asymmetrical shapes around the seat tube and rear wheel. This delivers an aerodynamic advantage of 6.3 watts compared to the previous generation. At the same time, the HB19 cockpit ensures a compact position thanks to the Plus-Four geometry, where the width at the shifters is 4 centimeters narrower than at the drops. Despite the larger frontal shape, the frame has become 124 grams lighter due to an adjusted carbon lay-up. In combination with Reserve 57|64 wheels, the shape of the rear wheel closely matches the seat tube for smoother airflow and a small but measurable gain in efficiency.

In practice, you choose this S5 Frameset when you want maximum speed without compromising stability or ride feel. The precise steering characteristics come into their own at high speeds, on flat stretches, and in technical descents. The generous tire clearance of up to 34 millimeters makes it possible to maintain comfort even on less-than-perfect roads, while the integration of the cockpit, saddle
