here is the Gear Track by Gladiator that is hanging on the wall. It is 2 pieces that I have on the wall and then tons of items you can add on with it. The hooks can be put wherever you want them at or whatever works for the widths you have. I have been happy with it.
I have a couple times noticed after humid rides there is a small wet patch underneath my bikes, didn't think they were that wet, could be coming from the chain. So I would recommend watching out if you are putting them inside somewhere to take care of carpet or wood.
