Box One X4 Pro Carbon Fork 20" Matte Black/ glossy black

The Box One X4 Pro Carbon Fork is a high-performance BMX race fork designed for riders looking for the perfect combination of strength, stiffness, precise handling and low weight.

Built around Box’s Oversized Technology, the X4 uses High Modulus Unidirectional Carbon Fiber fork legs, strategically engineered to increase stiffness in the areas where loads are highest. The reinforced fork crown and muscular shoulder design help reduce flex under hard acceleration, jumping and cornering, resulting in a more direct connection between rider input and bike response.

Unlike full-carbon race forks, the X4 features a strong and lightweight 7075-T6 aluminium 1-1/8” straight steerer tube. This makes the fork particularly suitable for larger and more powerful BMX racers who demand additional strength and confidence from their front end.

An internal aluminium butterfly reinforcement strengthens the critical connection between the steerer tube and fork crown, while the cold-forged 6061-T6 aluminium 10mm dropouts provide a durable and precise interface for conventional 10mm BMX hubs.

With its 32mm offset, the X4 delivers responsive and predictable race handling, while maintaining the stiffness required for explosive starts and aggressive riding.
