Factor OSTRO Gravel

DISCOVER THE ALL-ROAD ALL-STAR

Speed is your goal. Every ride, whatever the surface, faster is what counts, and this is the gravel bike you’ve been waiting for. The OSTRO Gravel takes its ‘win everywhere’ mentality from its road racer stablemate, the OSTRO VAM, and is likewise developed to dominate its category with incredible aero, superior handling, high stiffness and low weight. With a tire capacity of 45mm, it’s ready to go anywhere, fast.

REAL-WORLD GRAVEL AERO

Gravel racing is fast and aero really matters, but it isn’t as fast as road racing so the requirements are different. The OSTRO Gravel frame is carefully optimized for the speeds at which you’ll be riding. Our team used a ‘zoned aero’ strategy which focused the front of the bike on aerodynamics because it meets clean, or freestream, air flow, and the rear of the bike on lightness, where the air flow is too chaotic and ride quality is the priority. In particular, a lot of time was spent on the head tube, where an all-new tube shape unlocked significant drag reductions by manipulating the ‘laminar separation bubble’ that occurs near the front of airfoils at lower speeds. The tech is rooted in aerospace but all you really need to know is that the OSTRO Gravel will get you to your finish line faster, and by minutes, not seconds.

45MM TIRE CLEARANCE

The OSTRO Gravel offers a generous 45mm of tire clearance in both 700c and 650b, giving you the options and possibilities to tackle the toughest routes and events. This is a real figure, with 4mm of clearance either side in accordance with ISO standards, so the OSTRO Gravel is super-capable in muddy conditions. That was proven at the queen of gravel races, the 2022 Unbound 200, where heavy rain made the course brutal and the OSTRO Gravel was ridden to a top-10 finish.
