Impressive design. But not advisable if your coop is renting the space.
Wheels at our local coop.
Piles by sizes (24, 26, 26odd, 27)
Boxes of small wheels <20"
Hooks on 2x4s.
Just finished making a rim rack as well. Will post photos once it's assembled in place.
If you remove quick releases, that makes the wheels narrower and you can fit more.
alternate hook lengths by a couple inches and you can stagger the height a bit and get more side ways with the axles not hitting.
On the hanging bars we put the hooks in at 9 inch spacing. Good wheels get tagged with specs & price before hanging. mostly 700c roadie wheels. 700 c hybrid are still at a shortage as they just aren't strong enough.
3 storage units? Well storage units vary in size a lot. Take the time to cull the masses. I dismantle wheels all the time. A few each week in my spare time. Freewheels/cassettes removed. Tires removed. Intact rim tapes saved by size. Rusty spokes are cut out. Stainless are unspoked and the spokes and hubs saved. Oversize spokes are saved. Spokes are measured and taped in bundles by size with green painters tape and the size and count written on the tape. I have peanut butter containers of nipples sorted by steel, brass, long, short, medium, etc. Bent or cracked rims go in a separate pile for artists and sold for $1 each. Good rims are marked for size and spoke count. Many rims don't have sizes stamped on them so a sharpie helps. I write the size and spoke count on the inside of the rim next to the valve hole. The majority 0f the rims go to artists, very few are used to rebuild wheels. Hubs are saved intact as it's much easier to find a matching cone/axle for a hub than to try to sort and store the 100+ different cone specs.
26 mtb wheels are much stronger than 700 wheels so we have far more 26ers. Too many more. So I often will toss the older steel rim wheels from USA made mountain bikes of the 1980s and 1990s. I once sold 68 steel wheels in 1 shot to an artist. A heaping pick up truck load strapped down. There was no noticeable reduction in the piles. PS, welding steel rims is easier than aluminum for sculptures.
