Anyone riding one of these posts?

I have a Trans X cable less dropper on my hardtail SS, it’s only 100mm drop.

I mostly use the bike fir jump, pump, trials, so a dropper like this is an alternative to a quick release and a rigid post.

These droppers drop as much as 175mm, don’t weigh much, seem pretty maintenance free, and they’re cheap!

Any reason to avoid it?

I have the KS Exaform Speed Up mechanical post. It works great. I have it on a 'road' MTB I converted.

This hydro version looks like a manual lever KS eTen. Not 100% maintenance free, and heavy. I had one and eventually replaced it with something better. You can replace the cartridge if it fails, and what maintenance is required, you can do yourself.

If you're just looking for a cheap alternative to a rigid and using the quick release, I'd personally go with the mechanical version. I think I paid less than $75.

Crazy. Looks like the mechanical is NLA. I think my purchase was back in 2018? ...and the prices for the hydraulic are what I paid.

Specs. 'Only' 750g for the 175mm in 30.9.

Post is in. Will take a look after family movie night.

Star Wars 9 was ok the third time around

810g. And it is long. 558mm is a lot.

looks like it will fit in the N9 and put the seat at a good height for me on 160mm cranks. Wouldn’t work with the 175s.

Dropper is in. It was pretty rough the first couple of cycles, got better quickly. Seems to build a lot of pressure as you near the low position. Not sure if it’ll get better or not, I did about 3 cycles.
Summary - it’s a cheap dropper and acts like one. Seems serviceable though, more the Ford Escort experience than the Lexus experience.
it fits a Nimble9 2021 model and should accommodate down to about 33” pedal spindle to seat rail measurement and larger.

Cycled it 10 more times, it's smooth now, with some pop in the last 25mm of up and compression in the last 25mm of down. Trouble is it runs up pretty slow. Could be my seat clamp I guess, but I don't really think so.
I went ahead and ordered a regular 170mm dropper that was on Black Friday sale. It was $80 more (2x the price), but I know it'll work if I decide to take the bike cross country and need to cycle up and down a lot for features.

This exaform dropper is a step up from the quick release solid seatpost, and a step below a remote operated mainstream 2021 product.

Took a short ride on the Exaform. In use no problem with the raising or lowering speed. It doesn't snap up and hit your butt, but since you have ahold of the seat/lever, it works just fine speed wise, if feels fast enough.

Now I think the only downsides are the 150-200g weight penalty and the length.

Lo ciclé 10 veces más, ahora es suave, con algo de pop en los últimos 25 mm hacia arriba y compresión en los últimos 25 mm hacia abajo. El problema es que corre bastante lento. Podría ser mi abrazadera del asiento, supongo, pero realmente no lo creo.
Seguí adelante y pedí un cuentagotas normal de 170 mm que estaba en oferta del Black Friday. Costaba $ 80 más (el doble del precio), pero sé que funcionará si decido llevar la bicicleta a campo traviesa y necesito subir y bajar mucho para ver las características.

Este gotero exaform es un paso adelante de la tija de sillín sólida de liberación rápida y un paso debajo de un producto convencional 2021 operado a distancia.

I have the exact same model of Exa Form. I have been using it for a very short time, but I am surprised and uncomfortable at how difficult it is to compress it and especially how slow it is to recover its extension. Very hard and slow final. I don't know if it's normal, if it's defective, or if it needs some internal modification.

Thanks for the tips. 😊
