Dropper Seat Post Compatibility - Kona Mahuna 2021 I have a medium Kona Mahuna 2021 (Seat tube length 420mm and seat post diameter 31.6mm) which I would like to fit a dropper post on. The bike is 'dropper ready' with internal routing. I've never had a dropper seat before and I was looking at the PNW Loam, would this one with 125mm travel and 385mm seat post length be compatible?

It’s compatible regarding the diameter and actuator type, but the travel length is something that’s dependent on how much seatpost you have sticking out at pedaling height and how much maximum insertion depth your frame has. Can’t tell you whether it fits or not without that info.
