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.
