you must be referring to this layback detail on the controltech seatpost (pictured below and in my previous post)?
I do agree, it does seem unnecessary; however, if you imagine the post was completely straight with a 0 offset, you wouldn't be able to slide the seat back as far as you can with this
slight setback. It's a minimal difference though,
maybe a difference of 10mm? ...15mm?
Probably 5 mm at most bolt head to the front rail which is limited by the saddle rail bend choice..
Only the angle that the hole drilled through the ti tube is closer to the way the rail bend is in relation to the seat itself .
So sliding the seat rail is a bit more horizontal than if it ran straight thru ..
Maybe the kink gave them a bit more metal in the tube above the rear of the piece that pierces it.
