Driver, bearings, and hub shell. Hasn't skipped on me just yet. Has a clean sound without being degreased.
The axle is too hollow and it can bend easily, which I did by grinding. And both sides of the axle should be slotted, and the axle design should be like Joytech hubs so you can remove the whole axle without having to bang out the bearings.
A good hub for the price. It varies, some people get a defective hub, others don't. I'm missing a non drive side lock nut so I can't tighten down the cone nuts super hard or the hub will slow down. Overall, all I could possibly dislike on this is the axle and axle design, it's just too hollow and hard to maintain.
