Faster Than the Rest
Áspero-5 GRX RX825 Di2: The most aerodynamic gravel bike ever created — now equipped with Shimano GRX Di2 electronic shifting and a 4iiii power meter from the factory. Cervélo has long been synonymous with aerodynamic performance, and 30 years of that expertise went into this gravel race bike. A stunning 37 Watts faster than the outgoing model and 34 Watts faster than its nearest competitor.
The Áspero-5 made its rainbow-jersey debut — and won — under UCI Gravel World Champion Marianne Vos. Despite a significant increase in surface area to improve aerodynamics, it's also 66 grams lighter than its predecessor. The aero handlebar and carbon stem alone account for nearly 6 Watts of aerodynamic savings.
With clearance for 45mm tires, industry-leading downtube storage, and a threaded bottom bracket, Áspero-5 is ready to race the second it rolls off the shop floor. When fitted with equally-sized tires, the handling is stable and confidence-inspiring for the roughest courses. For less technical terrain, running a 4mm tire width differential (e.g. 40mm front, 44mm rear) sharpens handling and increases aerodynamics even further.
What Makes This Bike Special
Shimano GRX RX825 Di2 Electronic
Shimano's top-tier gravel-specific electronic groupset. Precise, battery-powered shifts engineered for the demands of gravel racing in any conditions.
4iiii Power Meter Included
Factory-fitted 4iiii Precision GEN3+ single-sided power meter. Race and train with data from day one — no extra purchase or installation required.
37W Aero Advantage
37 Watts faster than the previous Áspero and 34 Watts faster than the nearest competitor. The aero bar and carbon stem alone save nearly 6 Watts.
Downtube Storage
First seen on Cervélo's P-Series triathlon bike — the lightest, most aerodynamically efficient frame storage system on the market. Tube, tools, and flat kit inside the frame and out of the wind.
Reserve 40/44TA GR Wheelset
Reserve 40TA GR front and 44TA GR rear on DT Swiss 350 hubs. Purpose-built gravel rims that are tubeless-ready and centerlock compatible.
45mm Tire Clearance
Optimized for mixed tire sizing — run equal widths for stability on rough courses, or a 4mm differential (e.g. 40/44) for sharper handling and more aerodynamics on faster terrain.
