Suggestions needed - bike storage solution

[cmbicycles]

Im having trouble picturing what you want to do. Are the rings going to be stationary or moveable? If planning on moveable your ease of hanging, or taking down, a bike will be significantly less... The rings will create a constant moving target.

They make brackets that can be bolted to I-beams, might find something similar to work with conduit where you could fix it in a permanent position and thread a machine screw bike hook into it. At that point tbough, unless you like the look of the conduit it might be easier and cheaper to use regular hooks in a 2x mounted on the wall.
