  • These Box Lab Carbon Race Bars are a first of their kind, built specifically for younger riders with a custom hand laid carbon fiber construction that's the best balance between strength and weight.

    A high-level, race-orientated bar that uses Box's proprietary 28.6mm clamping area, designed to offer exceptional stiffness and unrivaled performance. There really isn't anything else like this on the market.

    Please note: the maximum recommended rider weight for these bars is 100 lbs.

BMX Handlebars come in either a 2 piece construction or a 4-piece construction. What one you choose is down to personal preference. 4-piece bars offer additional strength (and weight) and are popular mostly with Street riders. 2-piece bars offer a more classic look and are typically lighter.
