Review on Tranz-X Jump Seat: Cable-Less Dropper Post - The Ultimate Riding Companion by Raj Mazzabufi

I needed a simple folding seatpost with a seat lever for my gravel bike. I didn't need a big drop like an off-road endro, I wanted something light enough but most importantly I didn't want the stance to squirm and chatter. Many of the cheaper seat posts have noticeable lateral play. I'm happy to report that TransX is for you. Works great, well built, lowers and rises well enough for my 220lb frame. 4″ of travel is all I need, but some serious MTB riders would find fault with that. Very well made, tight as a drum, perfect for a gravel bike setup.
