Hub Extenders for narrow hubs

   For use with my large rotor adapter and narrow hubbed wheels commonly use on the R45 and R65, R80 and R80GS, and some R100's, especially European models. These wheels used the deep dished rotor 34111236005 intead of the more common 34111236566. The narrow hubs have 3 ribs instead of 4. The common 4 rib wheel is 52mm through the bolt holes. The 3 rib wheel is 42mm.  These will not work as an extension for OEM rotors.
