Hubs Madison bright
front hub .- Trabocchi mechanizes these components hub fixie starting from aluminium 6061 round bars whth a metal section of 71 mm . The hub housings go through four different processes of mechanization before being finished,resulting in a bright polishing with 6000ZZ sealed and armored roller bearings, providing lightness and smoothness when turning Forward flange is 70mm de perfil , opening between ends 100mm ,

The groove ball bearings are mostusual and especially versatile. They have low friction and are optimized for low noise level and low vibration,which allows high turning speed.Also they endure radial and axial loads both ways, are easy to assemble and need less maintenance than amy other bearing types. |
