Description
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
The drivetrain draws from two tiers of Shimano’s GRX gravel range. GRX 820 front and rear derailleurs handle shifting duties — putting the higher-tier shifting mechanism where precision matters most — while GRX 610 shift/brake levers and the FC-RX610 crankset manage input from the cockpit. The 2×12-speed setup runs 46/30t chainrings against a CS-HG700 11-36t cassette, delivering road-familiar gearing with enough low-end range for sustained gravel climbs. The 11-36t range keeps gear steps tighter than wider-range cassettes, which riders coming from a road background will appreciate when cadence control matters on mixed surfaces. GRX BR-RX410 hydraulic disc brakes with 160mm rotors front and rear provide consistent modulation in wet and dusty conditions alike.
Fulcrum Rapid Red 500 alloy wheels come tubeless-ready and roll on Maxxis Rambler 700x40c tires with 120tpi casings and EXO sidewall protection. The Rambler’s mixed-knob tread pattern transitions between hardpack, loose gravel, and paved connectors without excessive rolling resistance on smoother surfaces. At 40mm width, the tires provide enough volume for comfort and traction on loose terrain while leaving clearance within the frame for mud and debris.
MOST handles the cockpit with the Jaguar GR aluminum handlebar and Tiger Alu Aero stem, both routed through the TiCR system for a clean front end. Handlebar widths and stem lengths are matched to frame size across the range, scaling from 42cm bars with an 80mm stem on the 47 to 48cm bars with a 120mm stem on the 60. A carbon aero seatpost and Lynx Aircross saddle complete the contact points, with a Shimano SM-BBR60 Italian-threaded bottom bracket at the frame interface.
