The Box Hex Lab Carbon Rear Rim is a high-performance solution for advanced BMX race bike setups, engineered with Oversized Technology for maximum stiffness, control, and power transfer. Designed for elite BMX racing, this premium carbon rim enhances pedaling efficiency while improving rear-wheel stability under load.

Built from ultra high modulus carbon fiber using a precision vacuum-molded process, the Hex Lab rim delivers exceptional rigidity and responsiveness. Its engineered load-path design optimizes force transfer from the drivetrain into the rear wheel, producing stronger acceleration and improved control in demanding BMX track bike conditions.

The symmetrical dihedral angle stabilizers and sculpted spoke bed geometry allow the rim to achieve the stiffness of a wider profile while minimizing material usage. This results in a lightweight yet extremely durable race rim that maintains consistent performance across high-intensity racing environments.

Tubeless-ready compatibility and broad tire support provide flexible setup options, making it suitable for both technical and high-speed BMX race tracks.
