One Front Load BMX Stem - 31.8mm

BOX One Front Load BMX Stem in 31.8mm is a modern, race-focused stem built for BMX riders who want a stiffer, more precise front end with the security of a front-load bar clamp. Cold-forged and CNC-machined from 6061-T6 aluminum, it’s designed to hold alignment under hard gate starts, pumping, and sprinting while keeping cockpit setup straightforward. This stem uses a compact 28mm stack height and a +/-5° rise to help fine-tune bar height and reach without compromising clamp security.

• BMX racing-specific front load design - Delivers a direct steering feel and stable bar positioning under high sprint loads
• 31.8mm handlebar clamp - Supports oversize BMX race bars for increased front-end stiffness and precise tracking
• Cold-forged + CNC-machined 6061-T6 aluminum - Balances low weight with the strength and durability expected for racing impacts and repeated torque cycles
• Cold-forged, CNC-machined lightweight front clamps - Adds clamp stiffness for consistent bar hold and reduced risk of bar slip when properly torqued
• 28mm stack height - Keeps the front end compact for a clean, responsive cockpit setup
• +/-5° rise - Makes it easier to dial bar position for starts, manuals, and cornering without resorting to extreme spacer stacks
