Pinkbike debuted Crankbrothers' Highline dropper seatpost last April and it was their most significant development since the brand was reorganized under the Selle Royal Group. The Highline represented more than a new product from the Laguna Beach innovators. It was a mission statement—a demonstration of its redoubled engineering, testing, and quality control processes—and it was impressive in every respect.
In the Crankbrothers style, every part is beautifully machined and finished. Inside, its cable-operated mechanism can be disassembled and serviced by average home mechanics with a few simple tools. The primary element of the Highline is an easily replaced cartridge (backed by a three-year warranty) which ensures that in a worst-case scenario, customers won't be waiting for their dropper post to be serviced by the factory. I posted a
favorable first-ride piece shortly after the Crankbrothers launch and promised a long-term follow-up report, so here it is:

Crankbrothers InstallationSomeone put some thought into the Highline's installation process. To begin with, it's cable operated, and Crankbrother's decision to use Jagwire's best cable and housing means you may never need to service it, but if you do, a gear cable and some housing can be purchased at bike stores worldwide. I found that the lack of end fittings made it much easier to internally route the cable housing than a hydraulic Reverb hose, with its threaded metal ends. The fixed end of the cable slides into the actuator mechanism at the base of the post, which can be unscrewed by hand. The free end of the cable is fixed to the remote lever with a set-screw, which makes it simpler to fine-tune the housing length between the lever and the frame.
 | Positioning the Highline's remote is facilitated by its ball-and-socket clamping arrangement, which allows the lever to be rotated about its axis and angled to accommodate just about any rider's preference. |
Positioning the Highline's remote is facilitated by its ball-and-socket clamping arrangement, which allows the lever to be rotated about its axis and angled to accommodate just about any rider's preference. The low-profile handlebar clamp is only ten millimeters wide, so it can be nestled inboard or outboard of most any brake lever perch. The shift lever itself is quite comfortable, and its smooth, low-friction action made micro-adjusting the seatpost height a very intuitive process. Nuances, perhaps, but they add up. Extensions and retractions became seamless events—and returning to a competitor's dropper post was not always a pleasant transition.
Two-bolt seat-rail clamps have proven to be the easiest to micro-adjust, and the most secure method to retain a saddle. The downside, however, comes when it's time to replace or remove the seat, which often becomes a wrestling match unless one or both of the clamping bolts are completely removed. Crankbrothers eliminated the need to remove bolts (and the resulting shower of specialty hardware) by slotting the back of the seatpost head. Loosen the bolt, swing it free, and the saddle slides off and on in a more civilized manner.

Trail ReportI ran the Highline dropper post on two different bikes in mostly dry weather for nearly a year. I did manage to find a few mucky and rainy days to ride, but nothing like a serious rider would encounter in British Columbia's temperate rain forests. The post scores top marks for durability. It survived some impressive crashes in the boulders without any indications that harm was done. The sliding bushings are still intact and the post does not rock. The two-key indexing system also held well. To date, the side play is negligible—pretty much what I experience with reputable brand's posts when they are fresh in their boxes.
Crankbrothers say that the seal-head should be unscrewed, and the post lubricated each year. I didn't bother, as the protected area inside the post looked nearly new and was still moist with lubricant when I checked it for this report. The seal-head can be unscrewed by hand should you be curious about the health of your post.
As mentioned, the action of the remote lever, in combination with the post's smooth-operating rotary valve makes for one of (if not the best) modulating posts I've used. part of that control is due to the fact that the Highline extends at a metered rate—fast enough to satisfy most riders, but not so fast that it can't be stopped with a degree of accuracy mid-way through its stroke. Riders who demand an instant extension may find the Crankbrother's post to be too slow, but the Highline is what it is. Its cartridge system is not adjustable for speed like a RockShox Reverb with its manually charged air-spring. I prefer a faster post, but I grew to like the ability to precisely adjust the Highline's extension for technical trails that demanded a lot of pedaling.
Crankbrothers began the Highline project two years before the trend for longer-stroke dropper posts became the norm and there is no hiding that a 125-millimeter-stroke dropper post is the absolute minimum requirement today. The push for ultra-steep seat tube angles has upped the ante and the 150-millimeter post has eclipsed the 125 as the baseline standard for all-mountain and enduro style mountain bikes. If there was any complaint that I could level at the Highline, it would be that it desperately needs a big brother. Crankbrothers suggested that a longer-stroke version was in the testing stages at the launch, so I hope to see it sometime this year.
Pinkbike's Take: | Crankbrothers did well to make the Highline an exemplary dropper. If its only reason to exist was to assure loyal fans that the brand has returned stronger and more committed than it has ever been, the Highline would be a win. That said, if I didn't know anything about Crankbrothers, I'd still recommend it to anyone in search of a pro-quality 125-millimeter-stroke dropper post. Now, where's that 150-millimeter version? - RC |
MENTIONS: @crankbrothers
Shorter and longer travel options are in final stages of development and will be coming soon
Pretty crucial for trail bikes.
mans running a leopard print Vibrator for a seat, according to Bone Deth.
I can add that I've been riding the post in subfreezing (and sometimes sub-zero) temps for the last two months, with lots of road slop and salt thrown into the mix. The post only slows down slightly at sub-zero temps, and it operates as well as it did when new, despite the salt and road grime thrown at it.
- nice looking seatpost
This one looks awesome and certainly would consider it for my next bike.
Cheers,
CB products do not offer any advantage...well except some additional freedoms that come with CB clipping vs spd...and typically have a weak lifespan.
I maintain my Hope hubs annually. That's what keeps them going. Except for your grips and seat, there's not much else that is 'set and forget'.
*sidenote, I abhor CB pedals
Most shops can do it...takes 2 sec
thanks for the info!
Lets pretend youre a special little snowflake defending your countrymen with some misguided omerta
Edit - I'm aware of 200mm drop posts available, but it should be a norm by now
Racers who only want a smaller amount of seat drop, so that the seat stays at their knees when dropped, could tune for that. with small enough adjustments, I could get more drop than my current 125(still some seatpost visible) but less than 150(which would be too long for my current bike.)
eightpins has the right idea, but either needs to get better market penetration for their custom mouting system, or build droppers that will work with a standard seat tube as well.
There ya go, 199€.
Oh yeah...copying a feature used on taiwanese made 2-bolt seatposts for twenty years is really innovative apparently to someone being paid to write a glowing review.
I have both the SRAM brakes (Guide RS), and the Crankbrothers Mallet E pedals. Not a single problem. Haven't even thought about servicing the pedals; in all honesty, I doubt I ever will. Haven't bled my brakes since I've had them. Plenty of my mates have similar success stories with SRAM brakes and a variety of Crankbros products (pedals/wheels/dropper). I'd wager there are plenty more stories of a similar nature to be heard out on the trail.
Have you actually ridden the new SRAM brakes or with any Crankbros products from the last 5 years? If the answer is 'no', I suggest you actually go take them for a test ride, before making any half-baked negative statements about them.
credibility goes out the window
...HAHAHAHA
Don't buy shitty posts, don't need backup ones.
Still, I think they owe everyone who made the mistake of buying either of their previous failed efforts a free highline.
