The Box Two Center Clamp Stem is a revolutionary pro-level component that prioritizes both weight reduction and rider safety. Featuring a unique dual mid-bolt wedge mounting system, this cold-forged 6061-T6 aluminum stem eliminates traditional rear pinch bolts to save your knees from impact during gate starts. The open skeletal design provides maximum front-end stiffness while keeping the weight incredibly low for an alloy frame build. Engineered for 1-1/8" steerer tube forks (alloy or chromoly only) and 22.2mm chromoly bars, this track-ready stem delivers precision steering and superior power transfer to your pedals.

NOTE: This stem is NOT compatible with carbon fiber steerer tube forks. A minimum of 45mm of exposed steerer tube is required for safe installation.
