Cervélo S5 Frameset five black 2027: the aero road bike built for performance

A Cervélo aerodynamic road frame for a performance-oriented build

The Cervélo S5 Frameset five black 2027 is a top-of-the-line carbon frame designed to create a fast, integrated, and performance-oriented aerodynamic race bike. A benchmark in speed, the S5 relies on an architecture developed to reduce drag, improve high-speed stability, and maximize efficiency on fast courses.

This new generation of the S5 is announced as being 6.3 watts faster than its predecessor and 124 grams lighter. The main gains come from the front of the bike, with a deeper bayonet fork, an optimized head tube, and a new one-piece Cervélo HB19 Carbon cockpit, directly inspired by the iconic V-shaped stem of the S5.

Delivered with the Bayonet S5 carbon fork, the Cervélo HB19 Carbon integrated cockpit, the Cervélo SP34 carbon seatpost, the FSA SL IS2 headset, aerodynamic thru axles and Cervélo mounts, this frameset provides an ideal platform for building a custom aero bike designed for racing, sprints and high speeds.

Frame

S5 carbon frame geared towards pure speed

The Cervélo S5 Frameset 2027 is designed to maximize road speed. It's aimed at cyclists who want to create a high-end aerodynamic build that's efficient in races, sprints, attacks, and fast sections.

Faster than the previous generation

The new S5 is advertised as being 6.3 watts faster than its predecessor. The aerodynamic gains come primarily from the front of the bike, with a significantly redesigned fork, head tube, and cockpit.

Lighter despite aerodynamic optimization

Despite deeper profiles and increased surface area, the new S5 is claimed to be 124 grams lighter than the previous generation. Cervélo has optimized the carbon layup and components to improve the entire system.

Ideal base for a custom aerodynamic build

This frameset allows you to build a custom aerodynamic road bike, choosing the wheels, drivetrain, brakes and components best suited to your riding style and level of expectation.

Aerodynamics

A bicycle developed to reduce drag

The S5 is a Cervélo benchmark in aerodynamics. The frame shapes, bayonet fork, one-piece cockpit and overall integration are designed to minimize air resistance at high speeds.

Before the extensively reworked bicycle

The fork legs and head tube have been significantly deepened to maximize aerodynamic gains. This optimized frontal area plays a crucial role in the overall performance of the new S5.

Integrated asymmetric profiles

The integration of asymmetrical seat tube and rear wheel profiles contributes to aerodynamic gains. The goal is to promote smoother airflow around the frame/rear wheel assembly.

Designed for Reserve 57TA / 64TA wheels

The S5 2027 frame was developed in conjunction with the Reserve 57TA/64TA wheels, co-developed by Reserve and Cervélo. The rear wheel's asymmetry matches that of the seat tube to optimize airflow and overall performance.

Cockpit

One-piece Cervelo HB19 Carbon cockpit included

The frameset comes with the Cervélo HB19 Carbon one-piece cockpit. This integrated cockpit significantly contributes to the bike's aerodynamic gains while providing a very clean and high-end finish.

Plus-Four Concept

The HB19 handlebar uses the Plus-Four concept: the width at the hoods is 4 cm narrower than at the drops. This design allows for a more aerodynamic position at the hoods, while maintaining stability and control at the drops for descents and sprints.

Optimized size combinations

Cervélo offers several cockpit size combinations to adapt the S5 to the rider's position. The goal is to maintain aerodynamic gains while ensuring a consistent and high-performance fit.

Fork and steering

Cervélo Bayonet S5 carbon fork

The frameset comes with the Cervélo All-Carbon Bayonet S5 Fork. Its deep, integrated design directly contributes to the bike's aerodynamic efficiency, particularly in the frontal area.

Cervélo aerodynamic through-axles

The Cervélo Aero Thru Axle front and rear axles ensure a rigid, clean mount compatible with modern disc brakes. They also contribute to the overall integration of the bike.

FSA SL IS2 headset

The FSA SL IS2 headset complements the cockpit and fork integration, with a design tailored to the S5 head tube.

Included components

Cervélo SP34 carbon seat post

The frame kit includes a Cervélo SP34 Carbon seatpost, specially designed to integrate with the S5 frame and contribute to the overall aerodynamic efficiency.

Cervelo counter support

The Cervélo Front Computer / Accessory Mount 266 allows you to install a computer or accessory at the front of the cockpit in a clean and convenient way.

Cervelo rear support

The Cervélo Rear Accessory Mount is included to provide an additional integration solution for compatible accessories.
