That's right. A dropper for road bikes.

Shaking things up, KS took the formula for mountain bike droppers and brought it to your road bike in the form of the Zeta Dropper Seatpost. Yes, you read that right—a dropper for road bikes. Compared to other droppers in the KS catalog, the KS Zeta has a discreet, minimal appearance that might make you forget it's even there. Constructed with strong yet light alloy, the Zeta is cut-to-fit to accomodate rider height and features either 35 or 50mm of travel. Then, Integra cable routing tucks everything neatly into your bike's frame, while the carbon fiber remote quickly and easily mounts to drop bars for added convenience.

    Not accurate measurement information.

    I've used it once or twice and have initial impressions

    I have updated this review, original review will be the last paragraph. This is a very high quality dropper with smooth actuation and maybe the clearest and easiest setup I've encountered for a dropper post. My other droppers are Rockshox Reverbs which I would also rate highly, but require some more maintenance due to pneumatic activation. It is amazing how much of a difference 50mm in seat height can make. Just beware, as noted below, that this post will not allow the seat to be lowered almost to the frame like a Transfer or Reverb post, you will need to ensure that your post protrudes from the seat tube at least 129mm (by my calculations). This might allow you to customize for rider height but what is fails to tell you is that, even after you extend all the posts travel into the seat tube, you still have to have space for about 3 inches of post. In other words, this dropper does not allow your seat to descend almost to the top of the seat post, there is still most of it sticking out.
