Description / Columbus Compass Carbon Tapered Integrated Headset (1-1/8" - 1.5") – Black

Designed by Italian tubing and framebuilding specialist Columbus, the Compass Carbon Tapered Integrated Headset delivers the stiff, ultra-precise steering foundation required by modern disc and rim road, gravel, and cyclocross builds.

The upper assembly features an integrated 16 mm carbon fiber gap cap that serves as both a weather-resistant dust cover and an aerodynamic spacer, reducing the need for additional micro-spacers under the stem. Both upper and lower angular contact bearings (ACB) feature heat-treated stainless steel balls and races oriented at 45°×45° to handle high axial and radial forces under aggressive braking and cornering.

Key Features

  • Tapered Compatibility: Seamless interface for 1-1/8" to 1.5" tapered steerers (including Columbus Futura fork range).
  • Integrated Carbon Top Cover: 16 mm stack height eliminates excess spacers while providing a lightweight, low-profile finish.
  • Sealed Stainless Steel Bearings: 45°×45° Angular Contact Bearings (ACB) offer high corrosion resistance and low friction.
  • Direct-Drop Installation: Full IS (Integrated) fit drops directly into machined frame seats without pressed cups.
