Selecting a dropper post for my mountain bike was one of the toughest decisions I have made in a while. I had to determine the amount of travel I needed, if I should run an internally or externally routed cable, a hydraulic or a cable operated post, and consider the lever to operate the post. Price was also a major factor, especially considering I am currently a graduate student operating on a low budget.

After measuring my traditional, stationary seatpost and the seat tube on my bike, I knew what my limits were and thought I wanted 150mm of travel. My bike does not have internal cable routing but it does have a pre-cut slot near the bottom of the seat tube, which I assume is for routing an internal dropper post cable. With all of this in mind, I narrowed my options down to one post with few, but overall good reviews. However, the cost of the post was around $385 and it was covered by only a 1-year warranty. With my budget, and the history of dropper post failures, I decided I could not make this purchase.
A few rides later, and many “come to a complete stop, hop off, flip the quick-release lever, adjust saddle height, make sure it’s centered, flip the lever, hop back on” maneuvers later, I was back to looking at dropper posts. I had been hearing good things about the Crankbrothers Highline but wished it was available in 150mm. I set my saddle height 125mm below my preferred max height and ran through manuals, drops, and sharp corners and found that I could safely settle for 125mm of travel. The 3-year warranty from Crankbrothers and recent reports of satisfied customers sealed the deal.
Setting up the Highline was simple. I was a little worried about cable operation since I couldn’t find any documentation or reports of people using the Highline with cable routing like mine, but I have not had any issues with this setup. I did have to cut the cable housing a bit shorter than the manual suggests but this was not a surprise.
I now have over 90 miles and one crash with the Highline on my bike and I am extremely satisfied. Riding with a dropper post has not only significantly decreased the time transitioning between pedaling and downhill or technical sections, it has also increased the fun I have on my bike. When the post was brand new, it had only a very slight side-to-side rotational play. At around 1mm at the saddle’s nose, this is completely unnoticeable while riding, and even after 90 miles and a crash, the play has not increased. The post’s return speed has been said to be slower than some but I wouldn’t call it slow, and it is consistent throughout the travel. I just timed my post’s full rise time at 3 tenths of a second. I’m not sure how loud other posts are when they reach max height, but my Highline does have an audible but not obnoxiously loud pong sound, which I appreciate hearing on the trail.
I believe I made a great choice with the Crankbrothers Highline. Even though I initially wanted 150mm of travel, I have been completely satisfied with 125mm. The Highline feels very well built, and you can read about the lengths they went to develop a high-spec, solid dropper post. Sometimes products don’t live up to their specs, but in my experience, the Highline definitely does so.
