Your rear hub is this one:
Chosen Co., Ltd:::HUBS?Disc brake?wheel set
Front hub is probably an M9 version of this:
Chosen Co., Ltd:::HUBS?Disc brake?wheel set
Contact:
chosen.twn@msa.hinet.net
Ask for "April"
Make sure you send the same photos.
And then ask for the Cartridge Bearing Numbers #### for rebuilding the hubs.
Finally, I recommended checking the dropout alignments front and rear - cartridge bearing hubs are sensitive to dropout misalignment.
