Cervélo S5 Red AXS 1 five black 2027: the aero road bike built for performance

A high-end aero road bike equipped for pure speed

THE Cervélo S5 Red AXS 1 five black 2027 The S5 is a very high-end carbon aerodynamic bike designed for pure speed, sprints, attacks, and fast races. A benchmark in the professional peloton, the S5 2027 pushes aerodynamic efficiency even further with a faster, lighter frame and a one-piece cockpit designed to optimize the rider's position.

This new generation 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 Cervélo HB19 Carbon cockpit that adopts the iconic spirit of the S5's V-shaped stem, in an even more integrated version.

In this Red AXS 1 version, the Cervélo S5 receives an electronic transmission SRAM Red AXS E1 with a 13-speed single chainring, a crankset SRAM Red 1 AXS E1 50T Aero with power meter, a cassette SRAM Red XPLR E1 10-46 tooth cassette, Reserve 57TA / 64TA carbon wheels with hubs DT Swiss 180 and tires Vittoria Corsa Pro TLR G2.0 in 700x29c. An ultra high-end, radical and high-performance build, designed to exploit every watt.

Frame

S5 carbon frame geared towards pure speed

The Cervélo S5 2027 is designed to maximize speed on the road, whether racing, sprinting, attacking, or on rolling terrain. It retains the stability, precision, and handling that the S5 is known for, 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 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.

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 crucial area for reducing drag.

Aerodynamics

A bicycle developed to reduce drag

The S5 is a Cervélo benchmark in aerodynamics. The frame shapes, bayonet fork, monobloc cockpit and wheel integration are designed to limit air resistance at high speed.

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 major 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.

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 Red AXS 1 is equipped with the Cervélo HB19 Carbon one-piece cockpit. It significantly contributes to the bike's aerodynamic gains, while providing very clean integration and a very 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.
