Huh? Unless I'm remembering wrong, they're all standard metric industrial cartridge bearings that any good bearing house can supply. Bushings may be a bit trickier but there, too, the bearing house can usually match up for ID and OD if not length.


Beyond that, BETD is still making upgrade bearing kits for the '99s. they're ID'd for the Ground Control frames, but IIRC all the rear triangle/link pieces were the same.
