Where can i find a 61mm wheels for my inline skate?and im also wondering can you use different size wheels?
WD-40 was designed to displace water (wdwater displacement). It is an extremely light oil that can mix with water. It will work on skate bearings, if you want to use it every couple times you go out. Some racers use it and give every bearing a shot of it every time they skate. Almost anything will work in skate bearings but the general rule is the lighter it is, the more often you have to use it. Any of the spray materials are extremly light. A light machine oil will work well and you can get it in most hardware stores or hobby shops. It is really convenient if you get it in a needle oiler which is a narrow bottle with a long thin metal tip that is designed for getting the oil in small spots. You only want about 1/2 drop of oil in a bearing. For longer life, you can go with a gel or very light grease. About 3 pin head spots of grease or gell are about all you need if they are placed centered on a race.
