Cervelo Aspero GRX RX820 2025

The all new Aspero is here... Welcome to the world of speed gravel!

Cervelo may not have made the first gravel bike, but they definitely made the fastest gravel bike in 2019 with the introduction of the first Áspero, which took gravel riders across the world by storm, heralding a “new era of speed in gravel.” It was gravel, but Cervelo-style, taking all their knowledge of designing and manufacturing the fastest road bikes and applying that to the world of dust, dirt and fast adventures.

Since then, gravel bikes have grown, fragmented, and started to look a lot like the road and mountain bikes that spawned them, with suspension forks, bolt-ons for…everything, and ever-increasing tire widths. The new Áspero remains true to those early, simpler days of gravel, but with some improvements—a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAM’s Transmission drivetrains. But in true Cervelo style… IT’S FASTER!!

So how have they done this? To start with they shaved off three watts worth of frontal drag in the redesign process. Then they dropped the seat stays to give a bit more compliance out back, and reduced front-end stiffness slightly to make the last hours of a long race or the final miles of that epic adventure less painful and fatigue inducing . Between those dropped seatstays, Cervelo added in a bit more clearance for mud, too. It’s a lot of seemingly small improvements, but they add up to a lot. The result is a bike that feels a lot like the original Aspero, but is faster, more comfortable, and more versatile.
