CerveloS5 Red AXS 1 Road Bike 2027
The Cervelo S5 Red AXS 1 Road Bike is the definitive choice for riders who refuse to compromise on pure, unadulterated speed. Engineered with TrueAero tube profiles and an iconic integrated bayonet fork configuration, this machine slices through the wind with unmatched efficiency. This specific iteration takes aerodynamic dominance a step further by embracing a high-performance, single-chainring configuration inspired by professional TVL race setups. By eliminating the front derailleur, the bike achieves an even cleaner frontal profile, reducing turbulent airflow while delivering an incredibly focused, lightweight ride tailored for flat-out sprinters and breakaway specialists alike.
Pure Performance and Uncompromising Componentry
At the heart of this premium build is the ultra-efficient SRAM Red AXS E1 drivetrain, configured in a versatile 13-speed XPLR setup. A 50T Aero single chainring, equipped with an integrated power meter, pairs seamlessly with a wide 10-46T cassette to ensure you always find the perfect cadence without the weight penalty or mechanical complexity of traditional dual-ring systems. Stopping power is equally elite, utilizing SRAM Force hydraulic brakes with Paceline X rotors for precise control through tight corners and technical descents. Every touchpoint, from the one-piece Cervélo HB19 carbon cockpit to the premium Fizik Arione saddle, is selected to maximize stiffness, control, and ergonomic comfort during your hardest efforts.
Next-Generation Acceleration and Rotational Efficiency
What truly elevates this build is the revolutionary Reserve 42TA and 49TA tubeless-compatible carbon wheelset, laced to ultra-smooth DT Swiss 180 DICUT hubs. Featuring cutting-edge carbon-spoke technology, this wheel upgrade sheds a staggering 469 grams of rotational mass compared to standard configurations, allowing you to accelerate instantly out of corners and conquer rolling hills with minimal effort. Wrapped in supple, high-traction Vittoria Corsa Pro TLR 29mm tyres, this setup delivers a perfect blend of low rolling resistance, aerodynamic integration, and vibration dampening, ensuring that every watt you produce is converted directly into forward momentum.
