Thanks for all your interest and knowledge! i have nothing to add the modolo-discussion more than that's modolo flash sitting on the bike.. and, from my experience with the bike so far, changing the brakes to super record would make a difference.
BTW there IS a picture on the bulgier-site with a frame just like mine:

no facts exept that is ready to be packed and sent to the customer though...
