Cervelo

Aspero GRX RX820 Gravel Bike

What Our Gearhead® Experts Are Saying:

“Clean aerodynamics, Trail Mixer tuning, and the trusted GRX drivetrain make this one of the smartest ATB setups for riders who need versatility and speed.”

The Cervélo Áspero GRX RX820 is built to ride fast and respond consistently across varied gravel conditions. Its refined carbon frame delivers aerodynamic efficiency with compliance—thanks to strategic stays and an updated cable layout. The T47 bottom bracket keeps the handling clean and serviceable. The Trail Mixer fork ensures that both 700c and 650b setups feel equally planted, keeping your energy invested in the surface, not corrections.

Shimano’s RX820 package brings smooth mechanical shifting across a practical wide-range setup: 48/31T chainrings and an 11‑36T cassette give you the gear to lead descents or hammer climbs. Hydraulic Shimano brakes and CL800 rotors bring predictable power control at speed. Rolling on Reserve 30 GR AL rims paired with fast-rolling WTB Vulpine tires completes the performance foundation. With concealed storage, dual mounts, and integrated protection, this bike stays sharp longer and feels ready when the trail shifts.
