MacNeil Apex topload stem, 49mm, black

The MacNeil Apex Topload Stem in black is a heavy-duty, street-focused BMX component engineered for maximum clamping power and front-end lift.

Key Design Features

The original Apex design is built with a 49 mm reach, offering snappy and responsive steering. This makes it easier to pull into manuals and pop bunnyhops while maintaining high-speed stability. The updated Apex 2.0 version slightly reduces the reach to 48 mm, placing it in the ideal sweet spot for modern freestyle geometry.

Component Specifications

• Reach (Length): 49 mm (Original spec) / 48 mm (Apex 2.0 revised spec).

• Handlebar Clamp Diameter: 22.2 mm (standard BMX handlebar sizing).
• Steerer Tube Diameter: 1-1/8 inches (standard threadless BMX fork steerer columns).
• Stack Height: 28 mm ultra-low profile stack height.
• Material Construction: CNC machined entirely from premium 6061 billet aluminum alloy.
• Weight Profile: Roughly 300 grams (optimized weight-saving material cutouts).

Core Mechanism & Structural Features

• True Top Load Elevation:
  The handlebar clamp cradle is positioned on top of the stem body, naturally raising the handlebar height. This configuration is perfect for riders who want to lift their front end without using excessively tall handlebars.
• Recessed Fork Top Bolt Slot:
  The rear top section of the stem body features a precision-machined recess, allowing the fork's top cap compression bolt to sit flush within the aluminum casing. This prevents sharp edges from hitting your knees during bar spins or tailwhips.
• Solid Clamping Surface:
  Includes deep internal knurling inside the 22.2 mm bar bore and oversized hardened chromoly bolts, ensuring the handlebars stay locked in place under heavy landing impacts.

This stem delivers the perfect balance of durability, functionality, and modern freestyle geometry, making it a top choice for BMX riders who demand performance and reliability.
