Cervelo Aspero-5 SRAM Red AXS 1 - 2026

The Cervélo Aspero-5 Red AXS 1 five black 2026 is the gravel bike designed to be at the front of the race. It's the most aerodynamic gravel bike ever created by Cervélo, a brand renowned for its aerodynamic expertise for 30 years.

This model impresses with its performance, being 37 Watts faster than the previous model and 34 Watts faster than its closest competitor. This technical advancement allows cyclists to save precious time, thanks in part to an aerodynamic handlebar and stem that alone represent nearly 6 Watts of energy savings.

The Áspero-5 is also designed for versatility. It offers clearance for tires up to 45mm, integrated downtube storage, and a threaded bottom bracket. Ready to ride straight out of the workshop, it's already proven in competition, having won the UCI Gravel World Championship with Marianne Vos.
