BMX Racing Forks — Carbon Fiber & Cro-mo | Supercross BMX
Your fork is the most critical connection between your frame and the track — it determines your steering feel, your straight-line stability, and your confidence going into the first berm at full race speed. Supercross BMX and Speedline Parts produce some of the most advanced BMX racing forks available, from ultralight carbon fiber BMX forks used by our UCI factory team to proven chromoly race forks built for everyday racers who demand reliability every gate drop.

Choosing the right fork
- Axle size: Most modern race hubs use 20mm. Classic/budget hubs use 3/8". Check your front hub before ordering.
- Steerer type: Pro+ size frames typically use tapered (1 1/8" to 1.5"). Expert and smaller use straight 1 1/8" or 1". Check your frame spec.
- Material: Carbon for maximum weight savings and stiffness at the front end. Chromoly for durability and value.
