Attitude Inc Bearing Sleeve Kit for Harley Stainless Steel Axle Sleeves, 25mm to 3/4in., PairNever 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. These adapters take either a 1" or 25 mm wheel and reduces them down to fit a 3 4" axle. They won't change your existing wheel spacing.
