Cervélo Áspero-5 GRX RX815 Di2

STRAIGHT TO THE POINT

Our engineers love to say: “If it looks fast, it probably is!” And there’s truth in it because the Áspero-5 looks fast even while standing still. With no cables in the wind, aerodynamic tube shapes inspired by our tested library, and just enough clearance at the seat tube for optimal tire accommodation, this bike showcases its true purpose.

LIGHTWEIGHT SPEED

Some might argue aerodynamics don’t matter on a gravel bike, but if you’ve ever ridden into the wind across an open prairie, the 32 grams of aerodynamic drag saved by the Áspero-5 will be a welcome relief. Most gravel riding happens without the luxury of group drafting or World Tour tactics. When you're facing the wind all day, it’s good to know your bike is helping ease your burden.

TWO-POSITION ADJUSTMENT

The “trail” of a bike determines how the front wheel responds to rider inputs—a critical factor for high-speed handling. The two-position Trail Mixer allows you to adjust the front geometry to accommodate a wide range of tire sizes, ensuring consistent riding performance.

MULTIPLE CONFIGURATIONS

The bike is designed to comfortably fit most tire/wheel combinations: 700x42 or 650x49. Naturally, variables like rim width and tire tread depth will affect the fit.

Important Note: We always recommend maintaining a 4mm clearance between the frame and the installed tire.

SRAM INTEGRATED POWER

Red and Force versions include Quarq Zero power meters integrated into the crankset. Integrated power meters provide better stiffness, lighter weight, and greater accuracy compared to aftermarket solutions. The DZero offers precise power measurement within +/- 1.5%, even with varying temperatures.
