Great piece of equipment, heavier from the original by 29 grams, probably from bigger lip on the crown, beside that nothing to complain.
I don't think there is a real difference with Fanatec stuff. Materials seems to be resistant.
Simube hub is bit smaller compared to Fanatec one which is just what I needed in order to have all my wheels same. I had issue with my classic Nardi wheel for which I had to use adapter in order to be able to mount it (70x74mm hole pattern). Due to adapter wheel was closer to my for 2 cm and now with Simube hub difference is only 2mm. Me happy :)
