Cervélo Áspero-5 Frameset

That’s how Cervélo Áspero-5 debuted under the characters of the Wednesday Night Rough Club two years ago, and that’s how it’s stayed. And since, at Cervélo, we know that flat out doesn’t stay flat out for long without a little help from science, we’ve come back from the drawing board with a new Cervélo Aspero-5 Frameset. A faster Áspero, a lighter Áspero, and—dare we say it—an even better looking Áspero.

Our engineers like to say, "If it looks fast, it probably is"—but there’s some truth to it, and the Cervélo Aspero-5 Frameset looks fast standing still. No cables in the wind, tubes derived from our library of aerodynamically proven shapes, and just a hint of a cut-out in the seat tube to squeak out just a bit more tire clearance, add up to a bike that proves the adage. 

LIGHTWEIGHT SPEED
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.

TWO-POSITION ADJUSTMENT
Trail—front-wheel response to rider input—is the most critical factor in high-velocity handling. Flipping the two-position "Trail Mixer" to compensate for the difference in circumference between a 650b and 700c tire maintains consistent handling by maintaining consistent trail figures.

MULTIPLE CONFIGURATIONS
We designed Aspero to fit most 700c x 42mm or 650b x 49mm wheel/tire combinations. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 4mm of clearance between the tire and frame.
