Madison Satin Black - Hub

General Description

The Madison Satin Black hub with ball bearings is developed for fixie and track bicycles, intended for demanding urban and sportive use.

The hubs are machined through multiple processes from solid round bars of 6061 T6 aluminum (not forged) and feature a satin black anodized finish (not paint), ensuring durability, corrosion resistance, and a clean, uniform aesthetic. Smooth and reliable operation is achieved through the use of low-friction sealed bearings and a geometry designed for proper wheel building for both fixed gear and singlespeed applications.
