Aspero GRX 810 1x Gravel Bike

The Cervelo Aspero GRX 810 1x Gravel Bike exists to be a lightweight and speedy race-oriented alternative to the slower-paced jaunt of bike-packing, gear haulers. Cervelo claims the Aspero changes "the paradigm of the gravel bike design," and "is built to haul ass, not cargo." We couldn't agree more with that aim represented in this highly energetic gravel racer.

The Aspero is crafted with modern geometry aimed to combine comfort for the long gravel miles, with progressive fit to help you soar off the front of the pack. Trail is Cervélo's secret weapon in the world of geometry, and it comes into play on the Aspero to provide stability, regardless of the bike's size. Featuring a two-position adjustment to the fork's trail, you can now fit those super cushy 650b tires up to 49mm and straight-speed racing tires in 700c up to 42mm and maintain trail between 58.1 and 58.6mm, respectively. It means that every size of the Aspero provides similar handling characteristics between various tire and wheel sizes, whether gearing up for a full-gas cyclocross race of packing up for a night under the stars.

The Aspero comes equipped with the protection you need when things get rough, muddy, and gritty. Downtube protection helps keep your frame, and its sleek paint job, free of scratches and dents. Since gravel races tend to be long and self-supported, the Aspero comes ready to carry as much water as possible. Three bottle mounts, plus a bento mount on the top tube, provide ample room for bringing along the critical nutrition you need for all-day races. The Aspero utilizes the same bento mount as Cervélo's P5, and is compatible with all bento's built for the P5.

Shimano's dedicated gravel GRX groupset completes this Aspero build. A 1x drivetrain streamlines the ride, while a wide 11 - 40t cassette ensures the gearing needed for stout climbs. GRX levers have an improved shape and ergonomics for secure hand positioning and comfort across rough roads. GRX's rear derailleur is the crowning jewel of the groupset, with a clutch mechanism and improved chain retention to ensure smooth shifting well past the transition from chip seal to fire road. This particular model rolls on Easton EA70AX rims and 650b tires with a wide and trail-ready 48mm tubeless-compatible set of Panaracer Gravel King SK tires. And as ever with Cervélo, the Aspero runs with the wide and stiff BBRight bottom bracket, which doesn't flex under pressure when you're sprinting for the finish line.
