UPDATE
Yesterday I was contacted again by Specialized Rider Care Nordic that they had an update to my challenges and right now off the phone from a fruitful and very supportive conversation. It turns out that all of us were right, there are more than one version of the rear triangle and as a matter of fact 3 different versions to be exact. The version installed on all alu frames are quite different in design and have more clearance for a 29" wheel/tire combo. On the MY2018 one year only Carbon frames(Comp and Expert) there is a different design where Specialized also acknowledge that there is less clearance up against the motor thus not making it as capable as a dual wheel size bike compared to all the alu models.
It turns out that apparently rim design/tire combination is crucial in order to find a setup that will actually work on my exact model. The 29" test that
@Maastricht provided as well as the picture
@Jeff McD contributed with in another thread, is now being studied by Specialized and they have promised me that we will find a good solution to my Issues.
Thanks guys for the support!!!
