Aerodynamic tube profiles on a gravel bike seem like misplaced priorities until you consider that competitive gravel events regularly exceed 200 kilometers with sustained speeds approaching 70 km/h. Pinarello's Grevil F5 GRX610 takes this argument seriously, carrying over the Flat Back down tube profile and Fork Flap from the Dogma road platform to reduce drag where it accumulates most noticeably — around bottle mounts and at the leading edge of the fork where turbulent airflow begins. TiCR cable integration routes all housing internally, cleaning up the frame's aerodynamic profile and creating unobstructed mounting surfaces for frame bags and accessory storage on longer events. The result is a gravel bike that borrows road-racing aerodynamic thinking without compromising the geometry and tire clearance that rough terrain demands.

The gravel-specific geometry departs from road conventions with a shorter reach and taller stack that places the rider in a more upright, elongated position suited to hours of mixed-terrain riding. Chainstays measuring between 422mm and 425mm split the difference between responsive acceleration and compliance over rough surfaces. Pinarello tunes fork rake individually across all 6 frame sizes to maintain consistent trail, so handling characteristics stay predictable whether you're on a 47 or a 60. An increased seat tube angle opens clearance for both 700c and 650b wheel configurations, which means you can swap between road-width rubber for fast gravel events and wider 650b setups for rougher terrain without changing frames.

Toray T700 UD carbon fiber forms the frame, blending high-modulus and high-tensile fibers for a layup that balances pedaling rigidity against vibration absorption on rough ground. The Twin Arms rear triangle rotates the right chainstay and seatstay downward to create symmetrical deflection on both sides of the bike, evening out the frame's response to pedaling forces rather than letting the drive side behave differently from the non-drive side. This asymmetric construction carries forward from the Dogma lineage, adapted here for off-road demands where consistent frame behavior matters across unpredictable surfaces.... Read More
