Watch the super glues. It is brittle so any shock or impact to the ilder will most likely break the bond, such as turning and hitting the ilder or a rock, paver, tree, table leg, etc. A real easy fix on the idler, but a bit of an eye sore is to use colored micro zip ties around the spokes. When it's moving you can't see them but on the shelf if your staring at it, might gnaw at ya.
