I have bean wanting to upgrade the bearings on my old Shimano Calcutta 251 and wanted some opinions on bearings.  Has anybody used both Boca and Hawgtech?  Any difference between the two ceramic bearing from these companies?  

 

Thanks for the advice...

I believe the biggest difference is that the Boca bearings use a SS cage assembly, and the Hawgtech uses a polymer material for its cage assembly.  I prefer the SS as some cleaning solutions can damage polymer components.
