Familiarity: 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.
