The adaptor allows mounting 6-bolt GALFER Disc Wave® in all Shimano Center Lock hubs (not compatible with Fulcrum AFS System). It has two mechanical parts of black anodized aluminium and a metal washer to fix the disc. Installation is easy and quick, and you only need the specific removal tool for the outer Center Lock lock ring. Compatible for all wheel hubs, for big (15-20 mm) and small (9 mm) diameters.
