Box Two Axles

Box Two Axles

Product Overview

The Box Two are lightweight 20mm thru-axles machined from 7075-T6 aluminum with hollowed construction for weight savings. Available in front (20x100mm) and rear (20x110mm) sizes, they include CNC-machined aluminum nuts and fit most 20mm hubs on the market.

Key Features

• 7075-T6 Aluminum Construction – High-strength aerospace-grade material provides exceptional stiffness while remaining lightweight
• Hollowed Design – Internal channels reduce weight without sacrificing strength; optimized for racing applications
• CNC Machined Nuts – Two precision-cut 7075-T6 aluminum nuts ensure proper fit, secure installation, and consistent dropout overlap
• Universal Hub Compatibility – Fits most 20mm thru-axle hubs on the market, including Box One Quantum hubs
• Front and Rear Options – Available in front (20x100mm) and rear (20x110mm) configurations
• Ultra-Lightweight – Front weighs 77g, rear weighs 87g; minimal rotational weight for racing builds
• Precise Engineering – CNC machining ensures consistent quality and proper clearance with dropouts
