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.

The hubs are precision-machined through multiple processes from round bars of 6061 aluminum (not forged) 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.
