DETAILED TECHNICAL SPECIFICATIONS

• Product Type: Integrated Cable Routing Headset

• Bearing Size: 52mm - 52mm (Both upper and lower bearings have an outer diameter of 52mm)

• Dust Cover & Spacer Material: High-grade ABS plastic—durable, impact-resistant, and weight-optimized

• Bearings: Premium sealed steel bearings, designed with superior dust and water resistance for ultra-smooth rotation

• Compatibility: Ideal for carbon or aluminum frames with oversized straight/tapered headtubes designed to support fully internal cable routing from the stem into the frame.

KEY FEATURES

• Full Internal Cable Routing Support: The dust cover and spacers are engineered with dedicated channels/openings for seamless cable routing. Cables run directly from under the handlebar/stem, through the headset, and into the frame without being exposed.

• Smart Spacer System:

  • Includes aerodynamic interlocking spacers that can be split/opened. This allows for quick handlebar height adjustments without needing to disconnect or bleed brake and shift lines.

  • Sleek, rounded profile contours perfectly with specialized stems, giving the cockpit a clean, fully integrated, and professional look.

• Premium Sealed Bearings: Equipped with dual red-rubber sealed bearings to lock out water and moisture while retaining grease inside. Ensures frictionless steering, zero play, and long-lasting performance.

• Ultra-Lightweight Design: By utilizing high-strength engineering plastics for the dust cover and spacers, this headset significantly reduces cockpit weight compared to heavy aluminum alternatives.
