Box One Carbon 4.5" Handlebar

Box One Carbon 4.5" Handlebar

Product Overview

The Box One carbon 4.5" handlebar is an ultralight performance component engineered for competitive junior BMX racing. The advanced carbon fiber construction delivers exceptional stiffness-to-weight ratio while the compact 4.5" rise provides geometry optimized for junior riders without excessive reach or handling compromise.

Key Features

• Advanced carbon fiber technology – Premium carbon fiber construction provides superior strength and stiffness compared to aluminum; ultralight material reduces rotational mass without sacrificing durability
• Ultralight construction – 204 grams (7.2 ounces) delivers minimal weight addition while maintaining rigid steering response and control feedback across racing applications
• 4.5-inch compact rise – 114.3mm height geometry scaled for junior riders; provides appropriate reach and positioning without excessive rise common on full-size BMX bars
• 23.6-inch width – Proportional handlebar width optimized for junior frame geometry and rider size without excessive leverage or control difficulty
• 6° back sweep with 2° up sweep – Ergonomic sweep angles reduce wrist strain and improve control during extended racing sessions; geometry optimized for junior rider positioning
• 22.2mm clamp diameter – Standard BMX stem compatibility ensures straightforward installation without adapter hardware
• Professional installation required – Advanced carbon fiber material requires proper installation by qualified mechanics; specialized handling prevents damage and ensures optimal performance
• Impact inspection recommendation – Carbon fiber inspection after crashes or impacts ensures structural integrity and safety before continued use
• Maximum rider weight 100 pounds – Weight limitation reflects junior-specific engineering; exceeding maximum weight may compromise structural integrity
• Maximum torque 7Nm – Precise torque specification prevents over-tightening and material damage during stem clamp installation
• Direct manufacturer shipping – Shipped directly from Box One; ensures product authenticity and quality control
