Box One 24" 520x12mm 28h Rims

Box One 24" 520x12mm 28H Rim

Product Overview

The Box One 24" is a low-profile double-wall aluminum rim with no-nonsense design that eliminates excess material. At 287g (10.1 oz) for the brakeless version, it's among the lightest weight 24" rims available and features a 28-spoke drilling pattern.

Key Features

• Lightweight Double-Wall Construction – Optimized geometry reduces weight without sacrificing structural integrity
• Low-Profile Design – Eliminates unnecessary material while maintaining strength for racing applications
• Brakeless Surface – Aerodynamic profile optimized for speed; not compatible with rim brakes
• 28-Spoke Drilling – Standard BMX spoke count for balanced strength-to-weight ratio
• 520mm Size – Standard 24" wheel diameter (ERD 512mm brakeless)
• Ultra-Lightweight – 287g (10.1 oz) ideal for weight-optimized racing builds
• Front or Rear Compatible – Versatile design suitable for both wheel positions
• Anodized Finish – Durable coating resists corrosion and wear
• Precise Manufacturing – Consistent quality ensures true wheel builds and reliable performance
