Box 31.8 X 5.5" Handlebar Black Only Works W/31.8 Stem

Box one cro-mo and alloy handlebars are the first, modern, 31.8, oversize bars designed specifically for bmx racing. the added stiffness significantly improves bike handling while putting more upper body power into your pedal stroke. and that means getting out of the gate and down the first straight faster and accelerating quicker out of the turns. custom made from the highest quality chromoly and aluminum, the bars feature a proprietary 13-butted taper from 22.2 Ø at the grip area to 31.8 Ø across the lower bends.
