Using these Surly Big Dummy Mushroom Nuts is easy. Just remove the old nuts from your cargo deck and rack system and replace them with these new ones. Make sure to tighten them properly to avoid any loosening during use. When it comes to maintenance, periodically check the nuts for tightness, especially after long rides or when the cargo is heavy.
