Box One X6 Oversized Carbon BMX Fork

The Box One X6 Oversized Carbon BMX Fork brings Box’s race-proven carbon fork technology to riders demanding greater stiffness, control, and confidence from their front end.

Developed from Box’s title-winning X5 platform, the X6 incorporates Oversized Technology, strategically moving carbon from lower-stress areas into the zones that experience the highest loads during BMX racing. The fork’s larger shoulders and increased cross-sections aren’t just about appearance—they play a critical role in reducing deflection and increasing steering stiffness.

The result is a more responsive front end with sharper steering, reduced latency, and improved bike control during explosive gate starts, hard acceleration, cornering, and landings.

A 1.5" to 1-1/8" tapered alloy steerer tube provides a strong and stable connection between the fork and frame, while the larger fork profile provides increased tyre clearance for modern BMX race setups.

At the dropouts, cold-forged 20 mm thru-axle construction provides the strength and stability required for demanding race conditions. Combined with Box’s other Oversized components, the X6 creates a stiff, responsive front-end system designed to transfer rider input with minimal unwanted flex.

With a 115 kg rider weight limit, the Box One X6 is built for larger and more powerful racers looking for dependable carbon fork performance.

Less deflection. More control. Race-winning Box performance.
