Rollerblading is a sport enjoyed by young and old, from kids playing street hockey to adults engaged in professional rollerblading. Regardless of the level of rollerblading, you should always make sure that the wheels on your inline skates are properly tightened to prevent injury. Tightening the wheels is also an important part of the process of rotating the wheels, which you should do routinely to prolong the life of the wheels.
Hold the inline skate in your lap with one hand. The wheels should be facing up.
Insert the Allen wrench into the bolt of one of the rollerblade's wheels. Tighten the wheel by turning the bolt clockwise. Tighten as much as possible if the wheel has an aluminium spacer. Tighten until snug and then unscrew a bit if the wheel has a plastic spacer. This will help keep the spacer from breaking or deforming.
Spin the rollerblade wheel to check whether it's tight enough. Tighten the bolt further with the Allen wrench if the wheel wobbles. Unscrew the bolt a tad if the wheel sounds like it's rubbing, or if the wheel doesn't spin freely.
Repeat Steps 1, 2 and 3 until all wheels on both inline skates have been tightened.
The correct size Allen wrench will vary depending on the manufacturer. If you aren't sure what size you need, take one of the skates to your local hardware store and ask for help finding the right size wrench.
