I have seen that rack a couple of times and it has me totally confused...! I tried to find their webpage but failed, anyone have a link?

I am utterly ignorant on this rack so please forgive me if i am way of base but,.. what i just don't get is:

1. Is this rack really only attached to the seat post? Then why the redundant huge tube triangles just floating in mid air..?! Wouldn't a simple Truss design be just as strong and more sensible/light/look better? Why not in fact just use a normal style rack since this bike has eyelets for it? Doesn't the whole rack vibrate or move about due to the single attachment point?

2. Isn't this rack sortoff a bad idea on a Alu folder with an already "stressed" seat post (Big and heavy rider), won't the extra weight of the goods carried on the back lead to trouble with post and frame?

3. The huge main tube and the triangles would make it pretty heavy right? The only advantage i can see in this design is that it removes easily/quickly and won't impede with the fold, but aren't there quite some other racks out there with the same capabilities but that are of a more regular (strong/light) design.

Lastly it seems really high of the ground which is not ideal for carrying loads and stability....?

My apologies up front if i am in fact smoking carpet.
