Rubber-coated adjustable dumbbell
This is the lowest end dumbbell, and the encapsulation may even contain things like cement or stone powder. Of course, the currently popular iron-clad. This is also the most easily damaged, and multiple changes and beatings will make the outer layer of glue extremely vulnerable. The life span is questionable.
Electroplating adjustable dumbbell
At present, the most popular one, the first misunderstanding choice for Xiaobai users, is beautiful in appearance and high-end appearance. But after a few times it will lose shape. This is really about thinking twice before making a choice.
This is one of my favorite dumbbells. The processing technology is a whole cast iron block + outer layer dipping. I like it because it feels good. There are two classifications: smooth surface and pitted surface. The characteristic of the dipped dumbbell is that the dumbbell handle is relatively short and the grip is better.
The process of electroplating always faces the problem that the electroplated layer will fall off.
Do not drop stationary electroplated dumbbells.
