Cervelo Aspero-5

The Cervelo Aspero-5 is Cervelo's claim on the front end of gravel racing — the most aerodynamic gravel bike they've ever built, backed by 30 years of aero expertise that defines everything the brand makes. The numbers are specific: 37 Watts faster than the outgoing Aspero, 34 Watts faster than the nearest competitor, with nearly 6 of those Watts coming from the integrated aero cockpit alone. That performance showed up where it counts: the Aspero-5 made its competition debut under UCI Gravel World Champion Marianne Vos, who won in it.

Beyond the aero story, the bike is built to race: 45mm tire clearance, downtube storage, a threaded bottom bracket, and a direct-mount top tube bag attachment. Carbon handlebar, stem, and seatpost are included on every build. At RA Cycles, the Aspero-5 is available in GRX Di2, Force AXS, Force XPLR AXS, and Red XPLR eTap AXS builds across six frame sizes.

About the Cervelo Aspero-5

Cervelo has been synonymous with aerodynamic performance since its founding in Toronto, Canada — the brand brought aero to road racing before it was standard practice and has spent 30 years refining that expertise. The Aspero-5 applies it to gravel racing. Built around Cervelo's race-proven tube shapes, a fully integrated aero cockpit, and clearance for 45mm tires, the bike is designed to be raced from the moment it leaves the shop. Every build includes downtube storage, a threaded bottom bracket, and a direct-mount top tube bag attachment — details that matter on race days measured in hours rather than minutes. The Aspero-5 made its competition debut under UCI Gravel World Champion Marianne Vos, who won a rainbow jersey on it. According to Cervelo, it's 37 Watts faster than the previous Aspero and 34 Watts faster than the nearest competitor. Learn more at cervelo.com.
