OSTRO Gravel Force XPLR AXS 1X Gravel Bike

Factor OSTRO Gravel Force XPLR AXS Gravel Bike

From epic gravel races like Unbound 200 to long all-road adventures, the OSTRO Gravel Force XPLR AXS Gravel Bike is engineered to dominate. Its lightweight, aero-optimised carbon frame, gravel-specific geometry, and high-end components make it a versatile, race-ready machine that adapts to every surface and every rider. SRAM Force XPLR gives flawless wireless gear shifting, and the built-in power meter ensures you track every watt as you power over loose and technical terrain.

Aero-Optimised for Real-World Gravel Racing

Borrowing technology from the aero-road OSTRO VAM, the OSTRO Gravel applies a ‘zoned aero’ approach: the front of the bike is optimised for airflow, while the rear focuses on lightness and ride quality. Factor’s engineers spent extensive time refining the head tube shape, reducing drag at typical gravel speeds and manipulating airflow around the frame. The result? A bike that saves minutes, not seconds, getting you to the finish line faster in real-world racing conditions.

Versatile Geometry and Tyre Clearance

With 45mm tyre clearance on both 700c and 650b wheels, the OSTRO Gravel can handle the muddiest, roughest, and most technical terrain. Its steering geometry is designed around tyre size, ensuring precise handling whether using a 32mm all-road tyre or a 43mm gravel tyre. A lower bottom bracket, short chainstays, and optimised head tube angle provide a nimble, responsive ride without sacrificing stability, even on challenging off-road courses.

UDH and Black Inc THIRTY FOUR Wheels

The OSTRO Gravel features a Universal Derailleur Hanger (UDH), supporting the latest SRAM 13-speed wireless groupsets while protecting your drivetrain in crashes. Complementing this, the Black Inc THIRTY FOUR carbon gravel wheels maximise aero performance while maintaining crosswind stability. Their 25mm internal width and hookless design make tubeless setup simple, while CeramicSpeed bearings ensure ultimate efficiency across all terrains.
