There is nothing unusual about Kunteng's scattered beads and flower drums. Used in the low-end cars of Giant and Merida. If it doesn't explode, Kun Teng should be closed. Shimano Flower Drum is also a ball, but the quantum low-end ball flower drum can't compare with this, especially Shimano's labyrinth mechanism, which is a patent of Shimano, and can avoid sediment and rain from entering the flower drum as much as possible.

You can handle this kind of wheel for your purpose, but there seem to be more fakes on DH 19 wheels on Taobao than the real ones. I haven't studied how to distinguish it. I bought a fake DH 19 and dropped it without a trademark sticker. . . .
