Best Dropper Seat posts
Regarding the PNW Components Loam Dropper, MTBR believes that is stands out from the crowd of dropper seatposts with a great price, short stack height, and tool-free system to adjust the amount of seatpost drop. The travel of the Loam can be reduced by up to 30mm, in 5mm increments. If you need more adjustment than that, the Loam is offered in versions with 125, 150, and 200mm of adjustable seatpost drop.
On the other hand, "the OneUp's dropper post V2 is available in 120, 150, 180, and 210mm lengths and can all be shimmed down in travel by 10 or 20mm. The ability to fine-tune travel with the included travel shims, along with this post's category-leading low stack height (shortest total length per travel size), lets rider run the longest possible dropper for their saddle height. This is a huge advantage for shorter riders who want to run 150mm or even 180mm droppers on small and medium-sized frames. What else is there to like? Well, the price is really, really good."
