Cervélo Áspero-5 GRX RX825 DI2 1
The Áspero-5 wasn't designed for participation, it was built to win. This is the most aerodynamic gravel bike ever created, period. Cervélo has spent three decades perfecting the science of speed on the road, and now all that knowledge has been unleashed on gravel racing. The result? A bike that's an absolutely staggering 37 watts faster than its predecessor and 34 watts faster than anything else out there. Those aren't incremental gains, they're game-changing advantages.
But the Áspero-5 isn't just about wind-tunnel numbers. It's a complete race weapon ready to attack from the moment it hits the dirt. Clearance for 45mm tires means you can run the rubber that suits the course. Integrated downtube storage keeps your essentials secure without external clutter. A threaded bottom bracket ensures reliability when conditions get gnarly. This bike rolls off the shop floor race-ready, no compromises required.
The Áspero-5 has already proven itself at the highest level. It made its debut under UCI Gravel World Champion Marianne Vos, carrying her to rainbow jersey glory. Now it's the weapon of choice for some of the world's most elite racers who know that when the pace goes nuclear and the field shatters, every advantage matters. The Áspero-5 gives you those advantages in spades.

Sizing Guide
The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
