The Haro Lineage Topload Stem in black is a premium, high-strength cockpit component built specifically for BMX riders who demand a mix of vintage styling and modern durability. Unlike road or gravel stems, this component is designed for 20-inch freestyle and street BMX builds. The top-load design provides a noticeable handlebar rise, offering extra leverage for hops, manualing, and front-end control.

• Handlebar Clamp Diameter: 22.2 mm (standard BMX handlebar size)
• Steerer Tube Diameter: 1 1/8 inches (standard threadless BMX forks)
• Stack Height: 32 mm

Core Mechanism & Design Features:

• Recessed Compression Bolt Channel:
  The rear top section of the stem body features a machined recess, allowing the fork's top cap/compression bolt to sit completely flush with the top of the stem. This design prevents knee injuries during barspins or tailwhips.
• Beveled Aesthetics:
  The Lineage line pays homage to Haro's iconic 1980s design DNA while utilizing modern, lightweight weight-saving cutouts that maintain maximum torsional rigidity.
• Heavy-Duty Clamping:
  Equipped with solid chromoly bolts that provide clamping security to prevent your handlebars from slipping forward or backward during hard landings.
