Factor Ostro Gravel

Complete Build.

Born from racing pedigree and built to conquer the untamed, the Factor Ostro Gravel is not just another gravel bike — it’s a weapon of speed, precision, and style. Engineered with aerodynamic efficiency straight from the WorldTour, yet rugged enough to devour backroads and singletrack, the Ostro Gravel blurs the line between performance and adventure. Whether you're charging through a high-speed gravel race or escaping into the wild unknown, this is the bike that refuses to compromise — because neither should you.
