Killerdrop is a patented frame integrated dropper post solution that optimizes saddle position thoroughout its travel. 

It uses a standard dropper post that is clamped at the top of its stanchion to a tension bar that pivots around a point near the head tube.  This allows the steepening of seat angle and saddle pitch as the dropper extends, which puts the rider's center of mass in a more optimized position for climbing. 
Conversely, when dropped, the saddle is in a much more comfortable position for descending.

Licences are available to bike brands and framebuilders now.
