German Bearings Stomp Their Cheap Chinese Equivalents
The key components are total rubbish.
This test is simple and decisive, both bearings are weapons grade, yet the Chinese bearing cannot spin for more than a few seconds after being flipped. The bearings are not very round, this means friction, which means heat, which means wear, which means failure. These bearings are not sufficient for a child's bike, but they are apparently Chinese weapons grade.
The German bearing spins about 5 times as long as the Chinese bearing, and so it should last longer.
The Chinese may economically take over the world, but not in the near future, and not if they cannot develop new innovative products, and high quality products. Until then China will be little more than a manufacturer of trinkets, and baubles.
