Fork Expander Plug – Carbon Steerer Headset Expansion Plug

NZ$15.00

Protect your carbon steerer tube and achieve a secure, damage-free headset installation with this high-quality fork expander plug. Unlike traditional star nuts (designed for alloy steerers only), this expansion plug is specifically engineered for carbon and lightweight alloy steerers, distributing compression evenly and preventing cracks or deformation.

 

Key Features:

• Carbon-Specific Design: Prevents damage to fragile carbon steerer tubes by spreading compression forces evenly

• Durable Materials: Made from 6061 aluminium alloy + steel for strength, stability, and long-term reliability

• Enhanced Support: Provides added reinforcement to the top edge of the steerer, reducing stress and preventing splitting

• Easy Installation: Installs with a simple hex wrench—no hammering or special tools required

• Star Nut Replacement: Designed as a direct alternative to conventional star nuts (which are not suitable for carbon steerers)

 

Specifications:

• Material: 6061 Aluminium Alloy + Steel

• Expansion Range: 21–30 mm

• Steerer Size Compatibility: 28.6 mm (1-1/8”) or 31.8 mm (oversize)

• Weight: Approx. 41 g (30 mm length)

 

Package Includes:

• 1 × Fork Expander Plug

 

Ideal for road, MTB, gravel, and carbon fork builds, this expansion plug is the safe and reliable solution for modern carbon steerer tubes.
