BOX ONE Oversized Chromoly Flat Handlebars

The Box One Flat Chromoly Handlebars are built for riders seeking maximum front-end stiffness and precise bike control. Manufactured from premium 4130 chromoly steel, these handlebars feature Box’s proprietary 13-butted construction and Oversized™ 31.8 mm clamp interface for exceptional strength and steering precision.

Unlike traditional BMX bars, the Flat Chromoly bars utilize a very shallow 3° backsweep, providing a more direct riding position and enhanced control for riders who prefer a flatter cockpit setup.
