The HEIR Deheighter ™ , made by the combined forces of Kind Shock and Prevelo, is the first dropper post-compatible with Pivotal saddles. This dropper post will allow your little rider to push their seat down low with the flick of a lever for downhill shreds. And by using a Pivotal saddle, this dropper achieves ultra-low stack to fit small riders.
