Description
A patented steerer section allows for Columbus’ top-of-the-range road fork to bring integrated cable routing to 1-1/8” steerer diameters favored by the world’s leading framebuilders.
TREFOIL SECTION: The trefoil section of the fork steerer has been oriented for the optimal compromise between frontal and lateral rigidity, representing the market’s performance leading solution to integrating cables.
TUNED FOR HANDMADE: with the development of its patent-pending Trefoil steerer shape Columbus is able to offer an industry-leading internal cable routing system for the 1”1/8 – 1-1/2" steerer tube diameter. As steel and titanium tube manufacturers we consider this to be the optimal diameter specification for handmade bicycles made from our tubing.
ITALIAN MINIMALISM: Columbus disc brake Trefoil road-fork features a magnetic cover, that allows to enhance both functionality and aesthetic. In addition, the direct mount of the flat-mount caliper on the fork-brake, avoids the use of adapters, providing a lighter and stiffer structure.
