Similar to the Apex Deck, it is best to ensure that your wheel is tight, to reduce any stress on the axle, which can cause many problems.  If you can avoid riding flyout, we guarantee that any product will last longer. The force put on your scooter when riding flyout is something that scooter parts are not designed for.
