Does the piece of the dropper that attaches to the seat bottom out when you drop the seat? I want to drop the post as much as possible because I'm short.

YES! No more remote and less cables

It works great and is a lot smoother action than the air version with remove button/lever that I had before, from a different manufacturer. KS is my new go-to for dropper posts and I'll be ordering one for my kids and friends.


Do you have this is 27.2mm? Any other under the seat alternative?

Simple, solid dropper

I gave it as a gift but have feedback to share

I added this to my Cannondale Trail Singlespeed. I've become so accustomed to my dropper on my Bronson, when I'm out riding the singlespeed, I noticed the seat always being right there when I head back down the hill. I was shocked when I actually found a dropper in the older 27.2 size seatpost diameter. I like how simple this is, no extra cables and levers, which keeps my singlespeed bike simple, and purpose built.
