TranzX Jump Seat Cable-Less Dropper Post

Love this product. Well-made, works great, makes for an easy ride getting on and off the bike. I'm 74 yrs. old, had a total hip replacement, have trouble swinging leg over the seat, this works just as I had hoped. Great job, guys. Jean Montague

The single-bolt-does it-all bracket was jammed when I got it. I had to disassemble it and get the inner piece near the holt head unstuck. Then, with a handful of loose parts, each wanting to go its separate way, it took a minute to get the seat rails in the bracket and the bolt tight enough to let me get the lubed dropper post in the seat tube. I adjusted the seat angle, and height, torqued everything, then squeezed the lever. The seat popped up 100mm, 100mm above my intended seat height. The seat angle was good, but I lowered the dropper post four cm. I straightened the seat, torqued the seat post clamp to 4 nm, and took it to the driveway to try it.It's much easier to get on/off with the seat dropped. It's less nerve wracking to make a 180 in the grass at the end of the drive. I was able to raise the seat while riding, just stood on the pedals a bit. The coolest part was positioning the seat between its two extremes: lots of seat height options.I think this is a good value. Decent cable actuated dropper seatposts start around $170 and go up quickly from there. Electric ones are more. I don't plan any hairy descents with this, I don't race either. I've found myself on narrow obstacle strewn trails with long, steep slopes 10" from my wheel and my seatpost sky high. This will cure that. I think descending rutted forest roads this summer will be easier with a lower seat too. This is much better than adjusting seat height with the seat post clamp. Stop, lower the seat some, and roll on, slow and safely..Don't let my kvetching in the 1st paragraph put you off this great product. I think it might have been an open box item, or someone somewhere with a drill driver and 5 mm tip was in a hurry tightening the one-bolt-that-does-it-all.

Really impressed with this dropper post. I’m sure there are better out there but the complicity of being able to install this in 5 minutes and no cable routing to have to mess around with is great. Reaching under the saddle to adjust the seat height is easy to get used to and I was surprised at how quickly I’ve come to the view that I won’t go back to a normal post

i use it on my cargo bike and it weight in at 92lbs, this seat post is solid and function very well for the price , worth it , love it

I mountain bike 95% of the time but I have a Specialized Diverge Sport that I ride in spring on gravel and paved trails when the ground is still too soft in the woods. With long rides, I generally get uncomfortable, hands start going numb, etc. Wanted a dropper post to give options on my position but didn't want to route any cable or spend a lot of money for something I don't use that often. I was pleasantly surprised with how easy this is to adjust while riding, one hand does of to leave the handle bars but for on gravel and paved roads, no problem. Seems to be well made but haven't had it long enough for a good test. Might consider getting one of these for an old hard tail I have that mainly gets used when I talk someone into going mountain biking with me. For my main mountain bike I'd want a wireless or cable type dropper post but for what this is I can't fault it in any way.
