great external routed dropper post
this is a great dropper post for the money. Its hard to find a 27.2 dropper post as is. And this one has external routing wich made is perfect and easy to install on my GT aggressor pro. Now my bike had all the bells and whistles.

Works good
There are not many options for a 27.2 seat post these days. Installed this last week and have done a few rides so far. It has been working flawlessly so far. I put it on a 2022 Polygon Xtrada 7 size XL frame. I am 6’2”. This only being a 120mm dropper, I was concerned it would not be enough. Well, I was pleasantly surprised with the bikes geometry, it was plenty to get the seat out of the way. Only time will tell if it lasts.

Works well, but loudly
Works smooth and fast, but is much louder when fully compressed or extended compared to any other droppers I've heard. I wish it had 2 bolt seat adjustment but it's a deal at the price.

Works well and fast
Wanted an internal operated post to replace old worn external post. 27.2 size is getting harder to find. This one is a great replacement.

It works like it should.
It’s a dropper post. Push the button, squat and it goes down. Push the button again and the seat goes up your butt. I bought it and used it a couple weeks on the trail and was really happy. Took a trip up to Copper Harbor and realized how transformative it can really be even to have even a cheap dropper on an intense ride. Bought one for my wife’s bike right away.

Missing seat clamp hardware (main bolt that holds the clamp together.
There’s not a ton of options out there for dropper posts for 27.2 seat posts. This is a good option. It should have come with the seat clamp bolt. As it is, I MacGyvered a bolt and am using the dropper, but taking stars away.

I like it.
I installed the 120mm version on a Polygon Xtrada 5 and it fits and works perfectly so far. I can already tell this is going to greatly enhance my riding. I used to think dropper posts were a waste of money but not so much any more.
