Serious gravel riders and racers now have an ally in Pinarello's Grevil GRX Gravel Bike. Relative to the outgoing Gan, the Grevil is better in every area, such as its increased tire clearance, refined all-road geometry, a third set of bottle bosses under the downtube, and much more. Combined with all of the up-to-the-minute gravel standards such as flat-mount disc brakes and stiff 12mm thru-axles front and rear, this Grevil possesses comfort, classic Pinarello styling, and aero efficiency. This particular build pairs the capable Grevil frame with Shimano’s gravel-specific GRX drivetrain in a 1x and 650b Fulcrum wheels for an adventure-ready package.

The Grevil features similar eye-catching styling cues as the top-tier Dogma K10, with its signature curves, aero section, and asymmetry. Pinarello's goal was to make a bike that was fast over gravel and the road sections that connect them without relying on any suspension systems that can sap power. To do so, it relied on aero tube shapes that help slice through the wind and drop watts loss to air resistance as well as slightly flattened chainstays and seatstays that impart additional compliance over the bumps while maintaining lateral stiffness.

The most notable difference between the Grevil and its high-end cousin is the type of carbon used to make them. While the Grevil+ boasts the top-end of the top-tier Torayca T1100 1K Dream Carbon with Nanoalloy Technology, the Grevil consists of slightly more compliant T700 UD carbon, which gains weight and sacrifices a tiny bit of stiffness but drops the overall cost significantly. While this carbon is slightly less rigid than the T1100 1K, it remains a high-strength, race-worthy layup designed to handle hard miles over varied terrain. It's every bit as light and stiff as the bikes that many of our cycling heroes rode to grand tour and monument wins not that long ago. We should also note that, like most cycling fans, we still lust after those bikes even as technology pushes ever further into the future.

Since this is a Pinarello at the end of the day, we'd be remiss not to point out some of the aerodynamic signature features like an oval-front and FlatBack profile tube shaping throughout the frame and fork, creating an aerodynamic profile that slices cleanly through the wind without any extra materials bogging down the scale. Fork Flaps, an FSC integrated seat clamp, and aero seat post add to the wind-cutting advantage and offer clean, uninterrupted frame lines.

This particular version of the Grevil rolls on Fulcrum 650b wheels paired with Maxxis tubeless tires, so it's ready to take on those all-day chunky terrain routes you've been eyeing. A Shimano GRX 1x group handles shifting and braking duties with a wide-ranging gear ratio and powerful hydraulic disc brakes. With the XT range cassette, a single chainring makes roadside repairs all the simpler should your ride go a bit sideways. Final component shout outs include the brand's MOST cockpit which matches the frame's aesthetic and its intended use.

  • Pinarello's gravel rider and racer built up and ready for adventures
  • Specially designed tube shapes and layup smooths the bumps
  • Shimano disc brakes offer powerful braking and modulation in all conditions
  • 12mm thru-axles add stiffness and security
  • Precise and reliable Shimano GRX components have a wide gear range
  • 650b wheelset allows for wider tires and mud clearance
  • Clean internal cable routing keeps the frame tidy
