My-FELT-Surplus30-Plus - That's right I went to the dark side of the force, as it were. When I found out that the PNW Dropper seat post that I purchased and sent from America, didn't fit because of the "cink"/bend in the seat tube on the frames, I have been in search of another replacement Dropper Post to replace the KS Drop Zone, that came on the bike form FELT. Inside the box is the 2023 Fox “Factory” Transfer dropper post that features the 30.9mm post diameter in the 100mm Drop). The Factory model is priced at $350, but I got mine for $299 - including the normally $70 Fox Transfer lever. So I Post for $100 less than retail. Pricey? Yes, but People get on average 4-5 years of service, and I cannot believe how slick/smooth and quick the action is both going up and down. This dropper post is of a completely different (higher) caliber of Dropper Posts compared to the KS.
