Flat Out. That's how Aspero debuted under the characters of the Wednesday Night Rough Club two years ago, and that's how it's stayed. And because at Cervelo 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 Aspero. A faster Aspero, a lighter Aspero, and—dare we say it—an even better-looking Aspero.
Our engineers like to say, "If it looks fast, it probably is"—but there's some truth to it, and Aspero-5 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.
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 Aspero-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", or 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.
