Simple does it.

Dropper posts have certainly come a long way over the past few years, but the—despite countless tweaks and re-engineerings—hydraulic lines are still a huge pain in the ass to set-up and maintain. A brand like Crank Brothers knows a thing or two about simple solutions to problems that don't need to be as difficult as innovation makes them, and its Highline Dropper Seatpost applies the simple-does-it Eggbeater Pedal approach to the dropper world.

Instead of the above-mentioned, pain-in-the-ass hydraulic lines, the Highline features a hybrid system that uses a Jagwire cable to actuate a self-contained hydraulic cartridge. Set-up is simpler, function is more reliable, but it includes the smoothness of hydraulics where the post actually rises and drops. The 125mm travel is fully adjustable, and the cable itself routes internally to maintain the clean, uncluttered look of contemporary cockpits.

  • A dropper post that's actually equal to enduro abuse
  • Hybrid actuation is as smooth as oil but with cable reliability
  • Internal routing for a tidy cockpit
  • Remote switch is almost as infinitely adjustable as the post

Go with Fox Transfer

  • Familiarity: I've used it several times

Despite some of the positive reviews online, two separate bike shops I went to warned me of this post. Thinking that the internet knows better, I continued. Its first use came during a trip to Moab. The first ride it worked fine, though it was a bit slow. The second ride was a longer ride over several hours. In the last hour, the seat would not return and stayed depressed. I took it in to a Moab bike shop and they could not figure it out. They recommended the Fox Transfer (which all my friends had, go figure), and since I didn't want to be stranded on a trail with a slammed seat, I ponied up for the upgrade. The Fox Transfer works exactly as you'd expect, and appears to be the standard of reliability.


  • Familiarity: I've used it several times

This came spec'd on a bike I bought. The movement up and down was way too slow for my liking. Researched it, and it is apparently a fixed speed that cannot be adjusted.
If you dig slow motion, cool. But caveat emptor.

A year in, still great

  • Familiarity: I've used it several times

I have a full year on the 160 mm, 30.9 flavor. It's still working fantastic. No actual maintenance ever done to it. I agree it can be a little finicky if you have any sharp bends in the cable housing and there's an upgrade 'return spring' that's super easy to install and completely fixes that. I have had 3 dropper posts and this is probably my favorite of them all. The remote lever is perfect. I would rate this 4.5 stars if I could since I wish the return speed was a little faster. My post before it was a KS with the air cartridge maxed out though, so I got used to a very fast return.

Pretty Good

  • Familiarity: I've put it through the wringer

Fit and finish are dialed
Smooth actuation
Tons of lever adjustment
Low stack height

Finicky about cable tension. This could be due to bends / curves in the Yeti SB5 frame it's being used on, but I'm often adjusting the cable tension to keep the post from slowly extending when in the down position.

All in all, this is a solid post that has performed well, but maybe not the best fit for a bike that has multiple bends / sharp angles in the seat tube.

A big step forward

  • Familiarity: I've put it through the wringer

Crank Brothers has, in the past, been known less for the quality of their dropper posts and more for their pedals and packaging. This post blows all preconceived notions out of the water.
Incredibly easy instal
smooth, easy operation, not too hard to push lever
Crank Brothers finish and styling
Multiple positions and adjustability on the lever.

Slightly slower return
Sizes may not work on some newer bikes with lower standovers (no 170 option)

Quality and Reliability

  • Familiarity: I've put it through the wringer

I admit I am not the biggest Crank Bro's fan but this dropper has impressed me. It was easy to install and has been trouble free. The lever is awesome and has tons of adjustment on offer. Actuation is smooth and the return speed can be adjusted easily. Overall, this is one of the better droppers I have owned and if you're sick of being let down by less than reliable droppers I recommend taking a hard look at this one.

Mature, in a Good Way

  • Familiarity: I've put it through the wringer

In the last few years, dropper seatposts have gone from being an expensive, finicky curiosity to being an absolute necessity for going fast and having fun on the trail. With wider acceptance, expctations are raised for performance and reliability. The Crank Brothers Highline dropper meets those expctations and does so at a reasonable price. I have been using a 125mm dropper on my hardtail for nearly a year, and it has been flawless. I appreciated the ability to adjust the position and angle of the handlebar remote precisely. I also appreciated that the remote is included in the price of the post and not sold separately!

My complaints are pretty small. The overall length of the post is a bit long, so frames with obstructed seat tubes may be forced to run a shorter-travel post. The hydraulic cartridge is self-contained and sealed, so there is no ability to adjust the return speed of the post. On the bright side, there is no maintenance schedule, and no expensive an labor-intensive rebuilds. After a year, the Highline seems like a post that just works without requiring much thought!

Solid no-nonsense post

  • Familiarity: I've used it several times

Customer feedback on this post has been really positive. Durability over the long term is top notch, the weight is reasonable, and the remote absolutely rocks. I'm still all about the Pro Koryak, but I really love the highline!


  • Familiarity: I've used it several times

Well, after riding numerous droppers on the market, I have *fingers crossed* found the one that preforms the best. It has only been on the bike for a few months now, but no signs of play, issues, or anything. One of the best factory levers on the market, smooth actuation, and easy install make this post a win!

No worries here

  • Familiarity: I've used it several times

After having qualms with a few droppers in my past, I was hesitant to try this dropper as I hadn't used one before. From recommendation, I took the plunge and I've loved this dropper. Where others have been faulty in the past this dropper has had zero issues. Smooth functionality, and I paired with the wolftooth components lever.

A Reliable Dropper

  • Familiarity: I've put it through the wringer

This cable actuated dropper post works and feels great. The hydraulic post is smooth and the remote lever allows for quick adjustment.

The 160mm travel dropper is a welcome spec for taller riders.

will the crank brothers 160mm dropper seat post fit a large 2016 santa cruz 5010?

not asking the right question, what size seat post do you have? that will correlate with which seat post will fit

Seems high quality

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

This is my first dropper post, and I only have an initial impression. I was not sure what to expect, but the detail, fit and finish seem to be of very high quality. The installation and setup was easy, and I really like how versatile the lever is in the amount of adjustment options available. Top of bar, bottom of bar, further in, further out, it seems to be a very robust design.


  • Familiarity: I've put it through the wringer

After have several issues with the hydraulic switch on the my prior dropper it was a major relief to install this with no hassle and have it work flawlessly every time I use it. I have used it in near freezing temps all the way up to near boiling temps without any change in performance. This is now my favorite part of my bike. I love the lever it comes with. I was able to get it dialed into the perfect position. If you are looking at any of the post out there, this is the one I would recommend. The internals are simple (like the piston that hold the hatch open on your Subaru, so there is far less to go wrong), the lever is amazing, the install was a breeze.

most durable ever tried, great lever

  • Familiarity: I've put it through the wringer

I used for over a year, no maintenance required, same than day 1..Used in multiple conditions sub 10, over 90 always working. I love the lever micro adjustments too

Rough Start, but Now Great

  • Familiarity: I've used it several times

At first I was disappointed in the Highline dropper post because it was not holding position when adjusted. It could creep up or down. I spoke to a Crank Bros. tech, and he sent me everything (by overnight delivery) that could possibly be the source of the problem, including the hydraulic cartridge. The post is now working flawlessly.

This is my first experience with a dropper post and I was surprised that 125mm of travel is really a lot given my size (5'8") and style of riding. I should note that even with the new components it took a tiny bit of use for things to wear in and work perfectly.

Some pro reviews complained that the post rises slowly. Not mine. It's brisk, but not brutal.

This dropper post requires internal cabling, at least in the seat tube. My frame, a Diamondback, provides for that but makes the cable exit the seat tube through a rubber grommet near the bottom bracket. From there the cabling is external. When ordering check the dimension specs against your frame to be sure what you order will fit.

Still working well a year later with no maintenance beyond wiping dust off.

Heads up: 160mm may not fit your bike

  • Familiarity: I returned this product before using it

Ignore the rating; I'm sure the post works great on a bike it fits. I ordered the 160mm dropper for my 2015 s-works enduro, installed it, and realized it does not fit the frame--the seat tube is not long enough to fit the 465mm length. This is also an XL frame, so it definitely won't fit normal models. Lucky for me, and anyone who uses this site, backcountry seriously has the greatest customer service I have experienced in my entire life. I say that will no hyperbole or exaggeration, they are absolutely superb. My "greahead" Grant immediately called me after I sent him an email and set everything up for me to have a new dropper immediately. Backcountry is the best!

Heads-up: when you order the wrong size product you shouldn't give it a bad rating. Not helpful.

Not the Kronolog

  • Familiarity: I've put it through the wringer

I know, I know. You probably think Kronolog when you think "Crank Brothers Dropper". I'll admit that was hands down the worst dropper post i've ever personally ridden. I can say for a fact that the Highline is nothing like the Kronolog. I've been flogging it for the last 6 months now, and can only say great things about it. The best compliment that i can provide is that it still works. The actuation is really smooth, and the remote that comes with it has a unique adjustable ball joint that can give you multiple mounting positions. I got used to the action of a Wolftooth REMote that i was using with my previous post, so I stuck with that since it is also compatible. One pretty neat feature that i also like is that the stack height of the Highline is a lot lower than most other posts. For a shorter rider like me (5 foot 8) who due to seat tube clearance issues and had to run a Fox 100mm post, this post allows me to run a 125mm instead. No complaints at all about this post, highly recommend.


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

Crank bros dropper offers a smooth ride. Even in cold conditions, it continues to work reliably. No complaints about the cable mechanism, rain or shine.
