.I am the owner of a 2011 Ossa tr280i in Ontario Canada.It has the original rear hub bushing/bearing setup and it is need of a new bushing. I believe the skf # is "pcmf 353916 e".I know that there was a kit available at one time to convert the hub to bearing/bearings with a new pair of spacers.Does anyone know where i can obtain them? I tried local bearing suppliers,but they have a minimum order of $255. Thanks,Ric
