Stiff, Fast, Aero: Pinarello Grevil F Is a Pure Gravel Racing Steed

Four years after Pinarello launched its gravel racing-specific line of Grevil bikes, the brand is unleashing an updated version of the rig that pumps up the stiffness, aerodynamic profile, and power savings compared to the first run.

The Grevil F, like its predecessor, is all about speed. Pinarello says that when designing road bikes, it always works to pinpoint the perfect median among key features including carbon material, aerodynamics, weight, geometry, and tube thickness.

For the Grevil F, Pinarello stuck to the same mantra, prioritizing performance for riders who need power, stability, and speed, even when the road gets chunky.

The Grevil F starts with a frame composed of T700 carbon that combines both high-modulus and high-tensile-strength fibers that mix to create a build that is both rigid and forgiving. The bike is a sturdy platform that still absorbs vibrations from the trail, creating a more comfortable ride.

With three different build options, the Grevil F can accommodate riders who prefer only slightly rough terrain to those who are just about mountain biking.

The frame fits 700c road tires starting at 25 mm, 700c gravel tires from 32 to 50 mm, or 27.5 mountain bike tires up to 2.1 inches.

It also features a specially developed seat clamp in front of the seat post and embedded into the top tube. This is so debris flying off the rear tire — whether dust, mud, or whatever else — doesn’t find its way inside to gum up the system.

Even though the Grevil F thrives in rough terrain, Pinarello did not skimp on speedy features often reserved for the road.

First, the Grevil F’s frame keeps Pinarello’s asymmetrical design, addressing the different forces the rider applies to the drive versus non-drive sides of the frame. For example, the bike’s right chainstay and seat stay rotate downward to increase pedaling efficiency and damp impacts from the rear wheel.

The Grevil F’s Onda fork features a wave design and a 50mm rake that is light and pliant. And Pinarello’s Total Internal Cable Routing system ensures no errant cables hinder aerodynamics. The prominent front brake caliper shroud also displays Pinarello’s commitment to aerodynamics in gravel racing.

Compared to the previous Grevil line, Pinarello says the Grevil F update is 8% stiffer on the bottom bracket, 4% more aerodynamic, and saves 5 W at 40 kph.

The unpainted frame weighs in at 1,090 g in size 53. The Onda fork adds 500 g.

A complete bike without pedals equipped with Campagnolo Ekar and Princeton Grit 4540 wheels weighs in at 18.8 pounds in size 53. The same bike with Campagnolo Ekar and Fulcrum Rapid Red 500 wheels is 19.5 pounds.
