> Over 5000mi/8000km, everything is consumable, except hopefully the frame and associated components. I didn't blow up a hub over 7000 miles of touring, but I replaced chains, the cassette, the chainring that got the most wear, a couple of spokes, a rim, a saddle, and maybe a few other things. Oh, and several tires. That seems... unusual? I'm at 11,000 miles on my current road bike and I've replaced less than that even though I'm using components designed for weight, not durability. I'm on my fourth chain, third cassette, second rear tire (although both tires need replacement soon), and other than those the only things I've replaced are brake pads. Hauling a heavier load obviously increases wear and tear, but I wouldn't expect it to be that much.
