If you watch the video on the frame, they show a camera man jumping on one of the main tubes. So, I wouldn't worry as much about the bike gently hitting something, I guess, but I wouldn't want to get into a nasty tangle with those protruding bits or maybe a finger caught in one during a crash...
Again, their high end frame, which they said is MSRP of $6000, weighs only 1.8lbs. Why have multiple people now mentioned it being heavy, and one mentioning that another company has one that weighs 700grams? Those are about the same weight...
