Yeah, that's what I was thinking. I wonder if the extra stiffness is mainly in the crown and stanchions or if it is in the lowers as well.
It would be really nice to know more about the compatibility of parts between the Z1 and Fox 36.
Also, what offset(s) are available in the Z1 or did I miss that in the article somewhere? Does Fox vary their offset in the lowers or in the crown assembly?
