i just upgraded from a no-name ebay-purchased uni to a qu-ax luxus. my old uni came with thin rubber pads to place between the bearings and the forks, but the qu-ax doesn’t.
since i just happen to have a spare sheet of thin rubber lying around, would it be worth cutting some pads from this and putting them in? perhaps this would make it easier to get a tight fit without stressing the bearings?
my engineer flatmate suggests the rubber is only in the old uni to make up for crappy manufacturing tolerances, which seems plausible, even if the idea of fastening two smooth bits of metal together seems a bit weird to me.
