Four years after first entering the gravel world with the Grevil, Pinarello has unveiled the Grevil F, the latest in its line of racing gravel bikes

There is no denying that this new bike's intentions are racing, from its aerotube shape to its integrated cockpit. Its performance is further supported by the Italian creators' list of performance claims. They claim an 8% stiffer bottom bracket, a 4% improvement in aerodynamics, and a 5-watt savings when traveling at 40 km/h.

But the Greville F's standout feature is its balloon clearance, which accepts wider 700 x 50 mm tires. 3mm wider than Specialized's Crux, 8mm wider than Canyon's Grail, and 12mm wider than Bianchi's Impulso Pro, also from Italy. This makes the Greville F as versatile as the Gravel's versatility, so owners are not forced to trade off speed, comfort, and ability. With a simple tire change, riders can move between fast, light gravel terrain and more challenging technical trails, and the Grevil F can take this a step further with 650b wheels and mountain bike tires up to 2.1" wide.

The original Grevil was once described as a caricature of Pinarello's own design philosophy, with wave shapes on nearly every tube. However, it is clear that Pinarello endorses it, as it is difficult to tell the difference between the old and the new based on silhouette alone. At its core, this design is based on Pinarello's asymmetrical methodology, which adjusts the position and shape of the tubes to equalize the stresses on the drive side of the frame. As part of this, the seatstays and chainstays are rotated downward, and both chainstays are lowered to allow for tire clearance.

Pinarello redesigned the front end with a TICR (total internal cable routing) system to achieve the aforementioned 5-watt savings. In addition, Pinarello optimized the aerodynamics of the tube geometry and concaved the downtube and fork flap respectively to smooth airflow around the bottle and front disc brake calipers. [The S-Works Crux with the same specs weighs 7.25 kg, but is not particularly heavy for a bike designed for off-road riding. The unpainted frame weighs 1,090 grams and the fork 500 grams. The frame is made of the same Toray T700 carbon fiber as the Pinarello Prince, and each frame size uses size-specific geometry, so handling and stiffness are consistent across all models.

They also feature a threaded bottom bracket for easy servicing, and the seat post clamp is positioned forward to avoid obstruction by mud. Because it is race-specific, there are no mounts for mudguards or racks, but a third bottle cage mount is located on the underside of the downtube to carry extra water.

The Greville F is available in black, champagne, and green, the latter not available in the UK.

The Greville F with Campagnolo Ecar and Fulcrum Rapid Red 500 wheels is priced at £5,300, or £7,000 with an upgrade to Princeton Grit 4540 wheels. International pricing has not yet been announced.
