The Box Hex Lab Carbon Rear Rim is engineered for elite-level BMX race bike performance, using advanced Oversized Technology and ultra high modulus carbon fiber construction. Designed for competitive BMX racing, this premium rear rim delivers maximum pedaling stiffness, rapid acceleration, and precise power transfer under race conditions.

Developed with a full load-path engineering approach, the Hex Lab rim optimizes force transfer from pedals through the drivetrain into the rear wheel. This results in improved efficiency, reduced latency, and stronger forward drive on modern BMX track bike setups. When paired with other Oversized components, it creates a highly responsive and unified stiffness system for maximum race performance.

The vacuum-molded ultra high modulus carbon structure ensures exceptional rigidity while maintaining a lightweight profile. The symmetrical dihedral angle stabilizers and sculpted spoke beds enhance structural integrity, allowing the rim to deliver the stiffness of a wider profile without unnecessary material increase.

Tubeless-ready compatibility and broad tire range support make this rim highly versatile across different BMX race conditions, while maintaining consistent performance and control.
