Never again will you have to pass on a good deal at the swap meet because a wheel you want has the wrong bearings. No more fighting with the wheel to remove the old bearings, only to have to fabricate a new inner bearing spacer. Adapter kit PART #0215-1034 takes 25 mm wheels and reduces them down to fit a 3/4" axle. Adapter kit PART #0215-1035 takes those 1" bearings and necks them down to fit a 3/4" axle. Won't change existing wheel spacing. Solid stainless steel construction to prevent corrosion.
