There’s a widely agreed-upon saying that goes something along the lines of “Never change your gear the day before a race.” For many athletes competing at Unbound Gravel 2024, the historically challenging course often requires last-minute swaps to better accommodate the unpredictable conditions race day brings.

We spotted Rob Britton’s and Team Amani rider Jordan Schleck’s custom Factor Ostro Gravel builds ahead of the race and wanted to offer some insight on what goes into preparing for the biggest race on the gravel schedule. 

Both of these builds are based around the Factor Ostro Gravel frameset but both use different builds and component choices, as well as wildly different, eye-catching custom paint jobs. Kick back and check out this pair of spicy gravel race machines.
