So the bought by Razor.
It was really super. With enclosed wrench psyched replaced, turned off and drove off.
After a day saw the role as new, only was a gray coating to see dirt easily abzubekommen.
But after a few days and a couple of times quitschern (This happens to me quite often when I go Kurfen too tight) the tires had a brown coat is no longer left.
That looks stupid now the role looks very worn out.
Whether this role is better than the originals from Street Surfing I do not know, I'm beginning not so extremely driven.
By the way I'm talking only about the rear roller, since the front is still original and hardly worn.
