The Hex Lab Front Load is a modern 28.6mm, oversize stem designed specifically for BMX racing. When used with our Hex Lab Carbon Fiber Handlebar, you get the absolute stiffest cockpit available in this size. 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 Hex Lab Stems along with the Hex Lab Handlebars has noticed a major improvement in stability and control. Hex Lab Front Load stem bodies are "3D" 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.
