Cervélo Áspero-5 GRX RX825 Di2
Lightweight and aerodynamically efficient, the Aspero-5 offers more than just a competitive edge—it actively reduces drag, saving you valuable energy as you battle the elements. When faced with a relentless headwind, the 32 grams of drag saved by this bike can be the difference between breaking away and fading into the group. But the Aspero-5 isn't just about speed; it’s about control, too. With the two-position “Trail Mixer,” you can easily adjust for different tire sizes, ensuring consistent handling and a responsive ride whether you’re running 650b or 700c tires. Plus, with clearance for up to 700c x 40mm tires or 650b x 49mm tires, the Aspero-5 gives you the versatility to take on any gravel race, any day. Ready to conquer the terrain? The Aspero-5 is your ultimate gravel weapon.

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.
