Box One Os 31.8 Cromo 8.0" Handlebar

Box One OS 31.8 Cromo 8.0" Handlebar

Product Overview

The Box One OS 8.0" is a tall chromoly handlebar engineered with Oversized Technology to deliver maximum stiffness in a high-rise configuration. Constructed from 4130 chromoly steel using extruded and mandrel-formed methods, it provides responsive steering control and extended leverage for riders who prefer elevated bar geometry without compromising durability or weight.

Key Features

• Oversized Technology — Strategic variation in wall thickness and tube diameter distributes material efficiently, optimizing stiffness-to-weight ratio across the entire bar
• 4130 Chromoly Steel — Premium handlebar material offering superior strength and impact resistance compared to alternatives
• 13 Butted Construction — Variable wall thickness reduces overall weight while maintaining structural integrity in high-stress zones
• Massive Clamp Interface — 31.8mm clamp diameter maximizes contact surface with stem for locked-in steering precision and zero flex
• Extended Geometry — 8.0" rise with 7° back sweep and 2° up sweep provides elevated control point and extended leverage for varied trick progression
