Just seen on you tube that fanatec are going to be offering a new DD hub at an amazing price, around $350. Not sure from a business point of view why they would do that but anyone wishing to upgrade their gear has got to be interested.
If this is true then they are going to clean up on the middle price wheel market. https://forum.fanatec.com/categories/blog
It is much less powerful than other DD wheels. 5nm is about same than T500rs can do, and 8nm is about same than Clubsport v2.5. But accuracy and reaction speed are much better than in belt-driven wheels.
