The Box One Front Load is a modern, 31.8 diameter, oversize stem designed specifically for BMX racing. When used with our Box One Alloy Triple Taper Handlebar, or Box One Cro-mo Triple Taper handlebars, you get the absolute stiffest cockpit available. This added stiffness significantly improves bike handling while putting more upper body power into your pedal stroke, translating into more forward momentum. This isn’t just hype. Every rider we've worked with who have used the Box One Stems along with the Box One Handlebars has noticed a major improvement in stability and control. Box One Front Load stem bodies are cold-forged and CNC-machined from the highest quality 6061-T6 aluminum. The lightweight front clamps are cold-forged and CNC-machined for increased stiffness and strength.
