Cervélo S5 SRAM Red AXS Five Black road bike

Description

The Cervélo S5 SRAM Red AXS Five Black is a race-oriented road bike built for aerodynamics and speed, whether in the peloton or riding solo. It sits in the premium performance class for riders focused on marginal watt gains, integration, and the precision of electronic shifting.

Frame and geometry

At its core is a carbon composite frame with monocoque construction and a BBright pressfit bottom bracket, designed to boost stiffness around the crank area. The seat tube features an asymmetric profile to smooth airflow around the rear wheel. Up front, it uses a bayonet carbon fork integrated with the headset, allowing deeper profiles around the head tube. The geometry is race-focused and maintains a stable 55.6 mm trail across sizes 48 to 61.

For sizes 48 to 61, reach is 367 to 409 mm and stack is 496 to 608 mm. Chainstay length is 405 mm on all sizes, supporting direct power transfer. Wheel size is 700C across the entire size range.

Components

Drivetrain: SRAM Red AXS with wireless electronic shifting and 12 speeds. The SRAM Red AXS 50/37T crankset includes an integrated power meter, and the cassette is 10-33T.

Brakes: SRAM Red AXS hydraulic disc brakes are integrated into the shift-brake lever system. The setup matches the road standard for race use.

Wheels and tires: Reserve 57|64TA wheelset uses carbon rims with a 57 mm front depth and 64 mm rear depth. Hubs are DT Swiss 180, and wheel size is 700C.

Cockpit: The one-piece HB19 carbon cockpit integrates the handlebar and stem into a single unit. The Plus-Four concept makes the hoods 40 mm narrower than the drops.

Ride characteristics

The aerodynamic concept is built around deeper fork and head tube profiles, which have the biggest impact on air resistance. The seat tube asymmetry and rear frame shaping work with airflow around the rear wheel. The integrated cockpit reduces losses around cable routing and contributes to more precise handling at high speed. The 405 mm rear end supports eager acceleration when attacking and in sprints.

Who it’s for

This model is intended for experienced road riders who race, ride fast group rides, and do time-focused training. It makes sense for cyclists who want an aero bike without compromises in handling and with a fully integrated cockpit. Against other aerodynamic road frames, it bets on a system approach of frame-cockpit-wheels.
