Box One X5 24" 20mm Carbon Black Fork

Box One X5 24" 20mm Carbon Black Fork

Product Overview

The Box One X5 is a BMX race cruiser fork engineered with high-modulus carbon fiber construction and a tapered aluminum steerer tube for responsive handling and lightweight performance. Featuring a 20mm through-axle, oversized geometry, and cold-forged dropouts, it delivers the stiffness and durability required for competitive racing.

Key Features

• High-Modulus Unidirectional Carbon Fiber — Premium carbon construction provides superior stiffness-to-weight ratio, reducing rotational mass while maintaining structural rigidity
• Oversized Technology™ — Strategic material distribution and geometry optimization deliver maximum stiffness in critical load zones without unnecessary weight
• Tapered Aluminum Steerer Tube — 7000 Series aluminum steerer transitions from 1-1/8" to 1.5" upper diameter, accommodating standard headsets while providing increased stiffness at the fork crown interface
• 20mm Through-Axle — Industry-standard axle system provides secure wheel retention and precise alignment, eliminating axle flex and improving braking performance
• Internal Butterfly Steerer Interface — Internal geometry at steerer and crown junction optimizes load distribution and structural integrity
• Cold-Forged and Bonded Dropouts — Precision-engineered dropout design ensures accurate wheel alignment and durability under racing loads
• 32mm Offset — Geometry optimized for BMX cruiser racing, affecting handling characteristics and wheelbase dynamics
