how to put hubstack in FHZ?

i saw some videos in youtube…(i see a person who has an FHZ, the hubstacks are made of duncan bearing)
how do they do that?

(much better if it is a video tutorial)

please teach me!

:slight_smile:

I was wondering the same thing.

You can get an FHZ hubstack mod (kit). It is a longer axle or something in that area. But I am no expert on FHZ stacks.

Addment: You can make your own by using some spacers and bearings.

Yeah, you get a FHZ Hubstack Kit and some hubstacks.
