EXA Form 900i 30.9mm/31.6mm Remote Control Dropper Post with 1x Lever kit and Cable in Housing, 100mm/120mm Travel Dropper Seatpost

Seat post works great for an 85 lbs child. The item shipped without a required set screw for the piece to attach the control cable to the seat post, but we were able to make do. Otherwise, works as advertised.

So it took me about an hour and a half to install this right from scratch and a few little gaps on my part mainly due to the cable routing of my ebike. Overall I'm pretty happy with this I have no complaints whatsoever although I will say this my old one had a metal round 90 included in the cable this does not so unfortunately my old cable was damaged to the point that I was unable to use anything from it but this should have a gradual round 90 included would have been better. That being said all in all installation went fairly quick then straightforward of course attaching the seat takes about 5 minutes and it works perfectly how long it'll work for this I can't speak to but like anything else everything requires a little bit of maintenance and a seat dropper post once per season or twice per season again that'll depend on how much you ride and the conditions you ride in but I do annual maintenance I do monthly chain maintenance and things like that but this dropper post seems legit and no problems that's far.

You can't beat it for low price. Easy to install for any bike mechanic. Plastic thumb control is not very strong; reason for 4 stars. Definitely don't gorilla thumb your control! Lifting your weight off the seat prior to retracting the post could be a good thing, no unexpected seat drops during your ride.

Great value for the low cost. Compared to my tranzx, the cable design for the trigger is better. It has a stopper built in the cable rather than having a screw that presses down to hold it. We will put it to the test on trails but so far basic testing and usage says this is a decent post. Update: few weeks after cold weather, sometimes it gets stuck, might be a defect. We were able to tap the seat to trigger it but that would not be helpful during rides. If it continues we will drop stars and return it.

Good well made seatpost comes with everything you need for installation fit the bike perfect. As a bike mechanic I have installed hundreds of seat posts and this is a good one. All aluminum thumb control is nice
