Cervélo S5 Dura-Ace Di2 five black 2027: the aero road bike built for performance

A high-end aerodynamic road bike to maximize speed

THE Cervélo S5 Dura-Ace Di2 five black 2027 The S5 is a carbon aerodynamic bike designed for pure speed, sprints, attacks, and the fastest races. A benchmark in the professional peloton, the S5 draws on a long history of victories at the highest level, with a design conceived to maximize aerodynamic efficiency without sacrificing handling, balance, and stability.

This new generation of the S5 goes even further: it's announced to be 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 inspired by the iconic V-shaped stem of the S5.

In this Dura-Ace Di2 version, the Cervélo S5 receives an electronic transmission Shimano Dura-Ace R9200/R9270 12-speed, a dual-sided Precision Pro GEN3+ 4iiii power meter, Reserve 57TA / 64TA carbon wheels with hubs DT Swiss 180 and tires Vittoria Corsa Pro TLR G2.0 in 700x29c. A very high-end build, designed for cyclists looking for a fast, light and uncompromising aero bike.

Frame

S5 carbon frame geared towards pure speed

The Cervélo S5 2027 is designed to maximize speed on the road, whether in races, sprints, on rolling sections, or during high-intensity attacks. It retains the balanced handling for which the S5 is renowned, while further improving its aerodynamic efficiency.

Faster than the previous generation

The new S5 is advertised as being 6.3 watts faster than its predecessor. The aerodynamic gains come mainly from the front of the bike, with a significantly optimized 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.

Cervélo S5 bayonet fork

The Cervélo All-Carbon Bayonet S5 Fork directly contributes to the bike's aerodynamic performance. Its deep, integrated design allows for better management of airflow at the front, a key area for reducing drag.

Aerodynamics

A bicycle developed to reduce drag

The S5 is one of Cervélo's most iconic bikes in terms of aerodynamics. The frame shapes, bayonet fork, one-piece cockpit, and wheel integration are all 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 is one of the key performance elements of the new S5.

Integrated asymmetric profiles

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

Reserve 57TA / 64TA wheels developed for the S5

The Reserve 57TA front and 64TA rear wheels were co-developed by Reserve and Cervélo for the new S5. Their Turbulent Aero design is intended to work with the frame and optimize the overall performance of the bike.

Cockpit

Cervelo HB19 Carbon one-piece cockpit

The Cervélo S5 Dura-Ace Di2 is equipped with the new Cervélo HB19 Carbon one-piece cockpit. It significantly contributes to the bike's aerodynamic gains, while providing very clean integration and a 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.
