8000km mxus 30
bearing seized
20inch wheel
commutes with 70km/h speeds all year

think wd/40 killed them



wound up using other sidecovers i had handy
those bearings were a little chunky
pulled the dust seal off and grease was dry so repacked with grease





bought new bearings but the repacked ones are doing fine with about 2000kms on them
