Crankbrothers has been making its Highline dropper posts for quite a while now, but they haven’t been meaningfully updated in quite a few years. That changes today, with the introduction of the new Highline, an evolved, refined, and redesigned dropper post that’s made for “every rider, every trail, every day.” Crankbrothers says the new Highline is lighter, smoother, and more reliable, with shorter insertion depths, all of the sizing options, and adjustable travel for the perfect fit. 

The new Highline was designed to evolve, improve, and simplify our dropper post platform. By reducing insertion length, refining performance, and adding features like internal travel adjustment, we’ve made it easier for riders to maximize drop and achieve the best possible for for their bike and body.

Crankbrothers Highline Details

The new Highline looks a lot like most other droppers on the market, as well as its predecessors, the Highline 3 and Highline 7. But Crankbrothers assures us it is almost an entirely new product. That starts with the “sealed emulsification cartridge that strips away complexity in favor of proven reliability.” The sealed cartridge has a fixed, faster return speed and a simple design that’s intended to boost reliability and longevity.

At the base of the post, the new, low-profile actuator is roughly half the size of the blocky actuators on previous Highline posts. The shorter actuator helps decrease insertion lengths and makes fitment easier on some frames. At the same time, Crankbrothers says it has tuned the actuator and cartridge for easier actuation, a light touch at the remote, and a quick response.

The new Highline also features an internal adjustable travel system so riders can fine-tune the drop length to optimize fit. On the 30.9, 31.6, and 34.9mm diameter posts, travel can be reduced by up to 20mm in 5mm increments with an “easy-to-install key.” According to Crankbrothers, the process requires minimal tools and the post does not need to be completely removed from the bike. Note: the 27.2mm posts use a hydraulic IFP cartridge, and do not have adjustable travel.

The stack height has been reduced by 2mm to a very respectable 45mm (collar base to saddle rail center), and the brand states that insertion depths across all sizes have been decreased, too. The two-bolt saddle clamp has been updated slightly, but still features the quick-release, pivoting rear bolt that makes saddle installation, removal, and adjustments a snap.

More Sizes

Crankbrothers says, “No matter the bike, there’s a Highline that will fit.” It comes in 27.2mm, 30.9mm, 31.6mm, and 34.9mm diameters and travel lengths between 60 and 230mm (depending on the post diameter). With so many options, it does seem like there is a Highline to fit any bike.

Comparing 150mm 31,6 to OneUp V3:
-15mm higher stack height
-12mm longer max insertion length
-105g heavier

As for performance, we’ll have to wait for the reviews. But OneUp V3 is very fast and smooth, the spring mech works lightly (important when matching with a sprung remote), next to no saddle movement and reliability is second to none (have 3 of them in different sizes and never had any issues). Price is also competitive for what the user gets in return.

Crank Bros – good luck trying to compete against the absolute GOAT.
