Gravel racing is fast—and aero matters. But it's not road racing, and that means the aerodynamic demands are different. The OSTRO Gravel is engineered specifically for the speeds you’ll actually be riding, with a ‘zoned aero’ approach that balances drag reduction with weight and ride quality.

The front of the frame is where clean airflow hits first, so that’s where the aero gains are maximized. The rear? That’s optimized for lightness and compliance, where airflow is already chaotic and marginal gains matter less than how the bike feels over rough terrain.

Particular attention was paid to the head tube, where our engineers developed a brand-new shape to manipulate the laminar separation bubble—a phenomenon common at lower speeds around airfoils. Sounds like aerospace tech? It is. But all you need to know is this: it makes a measurable difference.

The result? A gravel race bike that’s not just fast in theory—it’s faster where it counts. Minutes faster, not just seconds.
