Aluminum spacers
For 4-wheel skates
Better Performance
8 pack of industrial airplane-grade aluminum spacers. 8 is what you need to upgrade your 4-wheel skates. Most older skates come with plastic. They were fine back in the day, but there is something better. If you like to go fast, dont be held back by obsolete hardware. These fit in virtually all brands of skates. The reason aluminum spacers work better is this: When you are in your skates your weight is pushing the skates into the ground and the wheels are pushing back up--this puts pressure on the spacers. An old-fashioned plastic spacer bends under your weight. As it bends it puts pressure on the inside of the bearings. The bearings are trying their best to spin, but they receive all this pressure that it impedes it from spinning as freely. Aluminum spacers are so strong--I dont care how heavy you are--they dont bend at all. If you try to squeeze these with pliers or a vise you cant do it--thats how strong they are. And they weigh virtually nothing!!!! Well, that minimizes or eliminates any drag on the bearings. Nowadays most high-end skates come with aluminim spacers. It is not the most exciting product in the world, but it makes a big difference in your skates performance. If you have an older pair of skates--this will give you a little turbo boost. If you like to do tricks and stunts--these are pretty much unbreakable-- If you play hockey and want a little more speed-- this is a small thing you can do to improve your game. These measure about 15/16" across or 23mm (They should be identical to the ones you already have--just a different material). The interior diameter of the hole where the axle goes through is 1/4" or 7mm. There are a few exceptions--if your axles are wider than this they will not fit, but there are not a whole lot of skates out there that have axles like that.
