runs easily, no damping

The wheel comes complete with quick-release axle. This I had to adapt my car (no problem).
Lying inside the wheel runs on two ball bearings which are unfortunately open. Since dirt can easily clean and affecting the bearings. I have two caps of my old cart used.
The wheel makes a solid, high-quality impression. The Assembly worked immediately.
The cart with the new bike was fucked off right :-) and has a few days to transport already few tons of ballast and concrete blocks. So fully loaded over grass, gravel, hard and soft surfaces. It does not show any weaknesses and is very stable, there to never, at 150 kg load the material drumming audible but none affected the transport case. Was striking how easily the full cart is absolutely Spurgetreu to push. Very good!
After a few days I then again on a rubber wheel with hose changed because the internal loss is non-existent more or less. Each stone, little holes or mini wave is guided directly by the truck arms. That bothered me then but more. as the higher force with the Schlauchrad.
Price-performance full reasonable, stable, runs very light, super Spurgetreu, clear-> never Plattfuss but no damping. Can I recommend
