To the Seven fans out there:

Is there any possible practical or aesthetic reason for the complication in the design of this frame???

for a big strong guy, it provides a very stable saddle platform on which to turn big gears. The more seatpost you have exposed, the more flexy things get. I hate flex in seatposts, so I am not a fan of the compact design for that reason also. And this is a dedicated TT bike where someone is more concerned about staying seated and turning over big gears, and any excess seatpost flex is wasted motion.
I am not convinced at allelviento

First, in TTing, where fluidity and smoothness is key, seatpost flex is never a problem. Also if you want just higher rear end, just get a sloping toptube like those 80's TT bikes. There is no need for multiple triangles here.

If we are talking about big strong guys, we are talking about someone like Abroham Olano. But if you remember, his bike has like 2 feet of seatpost sticking out, so that'd be 5-6 times of flex compared to this Seven.

I think it is a bad engineering job (whether by Seven or requested by the customer).

Is that your bike elviento? Are you interested in selling it? What size is it?

a triathlon or time trial bike. To keep the handlebars low and the seat at proper distance to crank (although that's quite a seat to bars drop, IMHO)and without an overlong stem, they extended the seat tube and gave it additional support. Purely a guess, however.

but for the real reason you'd have to ask the owner or Seven. Seven will modify their designs to fit the needs of the individual buyer. I suspect the owner of this bike had a specific reason and worked with Seven on the design and, voila, the above frame is produced. Unless someone here knows the owner or someone at Seven we can't really answer the question.

... it would appear to be an attempt at getting a minimal headtube... and stiffer main triangle... but judging by the stem/bar combo... there must be more to the story.

Be the bike.
drop the top tube so you can get a lower....tyrius

headtube height. This would allow for a huge drop from seat to bars and a very aggresive aero position. Would need to be very flexible to ride in this and also need to make sure you have to right seat tube angle so you don't lose power from a closed hip angle.

As someone above mentioned, may have been made for a tri bike.
