Cervelo Aspero GRX RX820 2x Bike Info
The Cervélo Áspero GRX RX820 2× is a high-performance gravel bike built to deliver speed, control, and versatility for mixed terrain riding. With its all-carbon frame and fork, dual chainring gearing, and refined components, it’s designed to conquer both fast gravel roads and rugged paths without compromise.
Equipped with the Shimano GRX RX820 2×12 drivetrain (48/31T crankset, 11-36T cassette), the Áspero GRX 2× offers expansive gear range for climbs and variable terrain. It uses hydraulic disc brakes for reliable stopping power in wet or muddy conditions. The full-carbon fork is tapered, and the frame features modern refinements such as a T47 threaded bottom bracket, cleaner internal cable routing, and compatibility with universal derailleur hangers (UDH).
The cockpit blends function and comfort: Cervélo’s AB09 carbon handlebars with flare, SP19 carbon seatpost, Prologo Dimension saddle, and Fulcrum Rapid Red 300 tubeless-compatible wheels wrapped in WTB Vulpine 700×40c tires. These provide a responsive, confident ride with enough compliance and tire clearance to handle varied gravel surfaces.
