By posting on an online forum, you are subjecting yourself to the opinions of others. This is a risk that you will have to take to get a definitive answer to anything. Not to mention.. What you are asking for is practically an opinion anyways.

Regardless of the fact, if I had to wager a guess (which is my opinion), they are probably the 'Hydroformed Cinelli Bullhorns' (Not the 2011's sorry) (31.8 clamp and seemingly aero flat tops) that come with the new Cinelli x Mash frame. Again, this is my opinion.
