Faster Than the Rest
The all-new Áspero-5 was built for the front end of the race, and is the most aerodynamic gravel bike ever created. Cervélo has long been synonymous with aerodynamic performance, and we’ve brought that 30 years of expertise to gravel racing. The new bike is a stunning 37 Watts faster than the outgoing model, and 34 Watts faster than its nearest competitor.
With clearance for 45mm tires, downtube storage, and a threaded bottom bracket, Áspero-5 is ready to race the second it rolls off the shop floor. It made its rainbow-jersey debut (and won!) under UCI Gravel World Champion Marianne Vos, and will be campaigned by some of the most elite bike racers in the world.

MAKE FRIENDS WITH THE WIND
You can, in fact, reinvent the wheel. Meet Turbulent Aero, a unique R&D program that leverages real world wind data to create the most rapid, stable, and best handling wheels in real world riding conditions.

SHAPE OF SPEED
Áspero-5 is 37 Watts faster than its predecessor, and 34 Watts faster than the nearest competitor. Cervélo has long led the industry in aerodynamics, and we’ve delivered a gravel race bike worthy of that reputation. The aero handlebar and stem are responsible for nearly 6 Watts of that savings on their own.

WEIGHT
The new Áspero-5 is 66 grams lighter than its predecessor, despite adding a significant amount of surface area to improve aerodynamic performance.

MIXED & MATCHED TIRE GEO
When fitted with equally-sized tires (e.g. 42mm front and rear), Áspero-5’s handling is stable, confidence-inspiring, and ready for the roughest courses. To increase aerodynamics even further, and sharpen handling for less-technical courses, we optimized the geo for a 4mm tire width differential (e.g. 40mm front, 44mm rear).

DOWNTUBE STORAGE
First seen on the P-Series triathlon bike, we’ve implemented our industry-leading downtube storage door on the Áspero-5. It’s the lightest and most aerodynamically efficient system on the market, and puts a tube, tools, and a flat kit inside the frame and out of the wind.

Frame Sizing
How do I determine what bike size I need?
The age-old question, isn’t it? There are many factors that go into bicycle sizing and fit, particularly for high-performance bikes. Without being able to measure you and see you on a bike, precise fit information is difficult to supply. It’s also not unusual for someone to be able to ride two different sizes depending on their goals, flexibility, and fit tolerance. That said, we have some fantastic retailers, and we’d encourage you to go start a conversation with them about what you want from your new bike. You can find the retailer closest to you on our Dealer Locator.
