Cervélo Áspero GRX RX815 Di2 gravel bike in review

May 2022 · By

The Cervélo Áspero GRX RX815 Di2 is designed for racing and made for gravel fans who love speed and chasing KOMs. Nevertheless, with an electronic 2x drivetrain and a classic two-piece cockpit, it should maintain good all-round capabilities. Our group test pits it against 18 of the best gravel bikes of the season to reveal whether this is the case.

Highs
  • Performance and ergonomics of the Shimano GRX RX815 Di2 drivetrain

  • Generous protection on the down tube

  • Carving fun on hardpack

  • Brilliant paint job

Lows
  • Vague handling when riding slowly

  • Limited mounting points
