  • ELITE PERFORMANCE DESIGN: The Box Two 22.2 x 1-1/8" Center Clamp BMX bike stem is cold-forged from aerospace-grade 6061-T6 aluminum, offering an exceptional strength-to-weight ratio. Its open skeletal design reduces unnecessary mass while increasing torsional rigidity for razor-sharp handling and high-speed stability.
  • KNEE SAVING INNOVATION: The Box Two 22.2 x 1-1/8" Center Clamp bicycle stem is engineered with a dual mid-bolt wedge system that relocates the chromoly clamping bolts to the center of the stem. This eliminates rear pinch bolts to reduce knee injury risk, minimize bulk, and enhance rider safety during aggressive sessions.
  • ULTRA LIGHTWEIGHT BUILD: The Box Two 22.2 x 1-1/8" Center Clamp bicycle stems are available in 48mm (213g) or 53mm (218g) lengths, this stem is built for agility and durability. A 22.2mm bar bore, ±5° rise, and compact 28mm stack height deliver a responsive cockpit feel ideal for sprinting, jumping, and technical riding.
  • ROCK SOLID COMPATIBILITY: The Box Two 22.2 x 1-1/8" Center Clamp bike stem riser is Designed to fit Box One XL, Box One X2, and Box One X5 forks with a 1-1/8" steerer tube. Requires a minimum of 45mm exposed steerer tube for proper installation. It is not compatible with carbon fiber steerer tubes.
  • BOMBPROOF DURABILITY: The Box Two 22.2 x 1-1/8" Center Clamp adjustable bike stem is manufactured through cold forging for maximum density and strength, then finished with a premium anodized coating and laser-etched graphics. Resists corrosion and wear while maintaining its high-performance look in harsh riding conditions.
