I agree. The bearings are inexpensive, and it certainly doesn't hurt to have extra bearings.

There is a very real possibility that Zongshen changed the design of the rear hub. I am busy enough here at China Riders, that I don't frequent other forums. If somebody finds four bearings in his hub, then he obviously needs four bearings. If he finds two bearings, as I did, then he only needs two.
