Not a problem yet.

I don't see a stack of mouldering centerpull brakes in your collection, their pads hardened to a granite-like texture.

Your cranksets also have both arms - you aren't holding on to a 170mm Shimano 600 Arabesque drive side crank "just in case" you find a matching left arm*.

You don't have nearly enough seatposts, or seat post 'guts' for older low end bikes.

I also don't see any axles, or quick release skewers.

Where are the mismatched pedals, or random single frame / bar pads from BMX bikes?

Also missing are the large stack of tires/wheels/rims/tubes.

Yes, I'm also the co-op for my neighborhood. How did you guess?

Edit: I also left out the random lengths of salvaged brake/derailleur cables & housing. Not to mention headsets & bottom brackets of various dimensions/threadings/fitments. And hubs**
