MADISON BRILLIANT HUB SET — Technical Specification

The Madison Brilliant Hub Set is designed for fixed gear, singlespeed, and track bicycles, providing reliable components with a strictly technical and functional approach.

Each hub is precision-machined from high-quality 6061 aluminum and undergoes three stages of bright polishing before final quality control to achieve a smooth and uniform surface finish.

This model does not feature anodizing; the finish is obtained exclusively through polishing.

The hubs are equipped with sealed cartridge bearings (6000ZZ), ensuring smooth and consistent rotation with standard maintenance requirements.
