What could be the reason for stem this far away I own a bicycle similar to this one:



(I replaced the handlebars with straight one on mine)

I know that there were some weird designs back in '90s, but some reason probably exists for creating a bike with such a long stem. Doesn't it create uncomfortable riding position?
If the bars were rotated back, they would not be so far away. And, if you wanted to tuck down and get more aerodynamic you could reach the part of the bar that is further away.
