The Basso Expander with Cap Ultra Clamp is an essential component for assembling carbon steerer tube forks, designed to ensure maximum safety, stability, and structural integrity without compromising performance.

Advanced engineering and design

Thanks to its 45 mm length, this expander ensures an even distribution of pressure inside the steerer tube, improving assembly stability and reducing the risk of localized stress on the carbon structure.

The ultra-low 1 mm support base increases the contact surface with the stem, providing a firmer and more secure clamping, ideal for racing and high-performance setups.

Performance and carbon safety

Specifically engineered for carbon components, this expander delivers:

Enhanced structural safety
Optimal load distribution
Full compatibility with modern forks
Superior stability compared to traditional systems

A technical solution designed to preserve the integrity of the lightest and most advanced materials in cycling.

Lightweight and reliable construction

Made of aluminium, the Basso Ultra Clamp Expander combines lightness and durability, making it ideal for road bikes and performance-oriented setups where every gram and detail matters.

Compatibility
Compatible with all forks featuring carbon steerer tubes

Why choose it
