2023 Cervelo Aspero-5 GRX RX815 Di2

Some might say aero doesn’t matter on a gravel bike, but if you’ve battled a headwind across an open prairie, the thirty-two grams of drag you’ll save with the Áspero-5 come as a welcome respite. Most gravel racing is done without the benefit of a World Tour peloton—or World Tour tactics—and when it’s your nose in the wind all day, it’s nice to know your bike’s shouldering a bit of the load.

“Trail” - Front wheel response to rider input - is the most critical factor in high-velocity handling. The ability to adjust trail with the two-position "Trail Mixer" to compensate for the extreme range of tire sizes ensures a uniform ride experience.

We engineered the bike to fit most 700x42 or 650x49 tire/wheel combos, comfortably. Of course, there are variables - rim width, tire casing/tread depth - which will affect final clearance. IMPORTANT NOTE - We always recommend there to be 4mm of clearance around whichever tire/wheel combo is installed on the bike.

Vibration-damping, carbon seat post we’ve used to great effect on the R5 and Caledonia-5, clever split-spacers under the stem so you don’t have to re-cable your bike to adjust your fit, and our new flared handlebar.

How do we push innovation further with every frame? At Cervélo we believe there are five distinct factors that can be looked at when it comes to improving a bike, and each is carefully considered by our engineering team as they develop new models.

Cervélo's approach to ride quality focusses on the rider's experience. We define ride quality as the feeling of the bike being appropriate for its intended use.
