I would out of principle. If it's a standard you know won't be replaced anytime soon, I'd stock up on tubes, mech hangers, cables, cleats, maybe chains... Not against trump in particular, but IMO there will be a point where either aliexpress falls off or gets banned/taxed so bad it's not worth it anymore (I think it already happened in brazil and it will happen in the west eventually)
Same with non perishable pantry if you ask me. If you have the space, it's a nobrainer to havea room full of pasta/toilet paper/other necessities. If it can't go bad, no reason not to stock it
