The Ultra Fortex Carbon Fork represents Ultra’s approach to high-end BMX racing components: precision engineering, carefully selected materials and performance-driven design without unnecessary compromise.

Developed specifically for the forces and demands of modern BMX racing, the Fortex combines a lightweight carbon construction with an aluminium tapered steerer tube. This combination provides the strength and rigidity required to handle the extreme loads generated during hard landings and high-speed cornering, while keeping overall weight exceptionally low.

Wind Tunnel Developed Aerodynamics
Every detail of the Fortex fork has been designed with performance in mind including the shape of the fork legs.

Rather than relying purely on conventional fork profiles, Ultra developed the Fortex around a highly streamlined leg design focused on reducing aerodynamic resistance.

Wind tunnel testing showed that the aerodynamic profile of the Fortex cuts through the airflow significantly more efficiently than conventional BMX race fork designs.

Carbon Performance. Aluminium Strength.
The Fortex combines carbon fork legs with a high-strength aluminium steerer tube.

Together, these materials create a carefully balanced construction focused on stiffness, strength, steering precision and low weight. All created with experience we gained over year in our Sport, BMX Racing.

Under 588 Grams
Performance without unnecessary material.

The Ultra Fortex Tapered 1.5 Pro Carbon Fork weighs less than 588 grams including the top cap.

An exceptionally low complete weight for a BMX race fork designed around the demands of high-level racing.

The finish of the Ultra Fortex Fork you see here has been specifically selected to match the new Stay Strong Grail C.1 Carbon Frames, allowing riders to create a clean, integrated and premium race build.
