You going for one Martinh?
I emailed Banshee and they replied saying:-
You are correct and its something we call the “shock block”. It makes a huge difference to soften the feel of the aluminum but you wont give up the lateral rigidity of the frame. Its super stiff and that will allow the power to the pedals.
I will be honest though my friend Lance Canfield did say it was bloody harsh, but he’s used to his own plush DH bikes and has had a few back surgeries. Others who have ridden the bike had no complaints and to be honest with those big fat wheels I found it less harsh then the Scirocco I used to ride which the Paradox is based off of but it was a 26”
