Pinarello took a holistic approach to their new gravel bikes, the Grevil and Grevil + (pronounced “Gre-veell plus”). Anyone can make a gravel bike, but they wanted to make a gravel bike with true Pinarello DNA. Translation? Ensure their new bike has the handling, stability, and responsiveness typical of the brand, regardless of build, tire, or wheel size.
Yes, wheel size. The Grevil and Grevil + fit both 700c and 650b wheels, and tires as big as a 27.5 x 2.1”. Like OPEN and 3T Cycling, Pinarello achieves this variety of tire and wheel sizes with a short 420mm chainstay with a dropped chainstay. Many call it fashion; we say it allows the chainstays to be wide enough for optimal stiffness without compromising wheelbase length or tire options.
The company from Treviso didn’t just call it good with a dropped chainstay. Having touted their Think Asymmetric philosophy for years, Pinarello found that a dropped chainstay substantially changes energy transfer from the wheel to the saddle. So they designed what they’re calling their Twin Arms technology. In short, because the drive side chainstay is dropped, the drive side seatstay ought to be dropped as well to ensure the rear of the bike responds to stress similarly. Small details, but they make all the difference in making a bike that is hollistically cohesive.
Much is shared between the Grevil and vaunted Dogma series. The Grevil receives flourishes such as a concave downtube for improved aero around the water bottles, and provides a little opening to integrate a Di2 junction box. The now-ubiquitous Onda fork and Fork Flaps are found here as well, with the non-drive side much bigger to smooth air flow around the disc brake caliper. Pinarello added a third bottle cage under the downtube (where air flow isn’t as important), as well as the comfort-laden seatpost from the Dogma K10. All in, features like these make the Grevil that much more versatile on and off the beaten path.
Geometry plays a substantial role in dictating the character of a bike, and the designers went to great lengths to ensure that the Grevil and Grevil+ ride like a Pinarello. Reach and stack numbers are similar to what you’d find on the Pinarello Gan K, with just a touch more stack. Pinarello managed to ensure that the wheelbase is only about 2.5% longer than the Gan K despite much greater tire clearances.
The Grevil gravel bike is available in two carbon grades: Grevil with Toray T700, and Grevil+ with Toray T1100 1K found on the Pinarello Dogma. Delivery is expected in March 2019.
