Adjustable Travel

Adjustable Travel

We added a new adjustable travel system that lets you fine-tune your dropper height for a perfect fit. You can reduce the travel by up to 20 mm in 5 mm increments by simply repositioning the keys on the quill; no extra parts needed and no need to remove the post completely from your frame. For example, you can start with the 230 mm post and adjust it down to 210 mm in 5 mm increments for the perfect setup.
Actuator

Actuator

The new, low-profile actuator is nearly half the size of the Highline 3 & 7 for improved frame clearance. We also tuned the cartridge so that it requires less force to drop and gives the post a smooth feel with a light touch and snappy response.
Reduced insertion length

Reduced insertion length

The shorter insertion depth allows to fit a wider range of bikes, including those with extra-small and small frames, as well as bikes with tight tolerances.
Low stack height

Low stack height

The distance between the seatpost collar and the seat rails is minimized, allowing riders with shorter legs or bikes with longer seat tubes to run longer-travel droppers. This adjustment means the saddle sits lower when fully compressed, providing more comfort and freedom of movement on the trail
Head

Head

The Highline’s two-bolt saddle clamp includes a quick-release rear bolt, allowing for easy installation and quick saddle adjustments. It has a 45 mm stack height measured from the collar base to the rail center when fully dropped.

FAQs

The Highline dropper post package includes the dropper post, cable, housing, caps for the housing, and a ferrule to crimp on the cable end.

First, determine whether your bike uses external or internal cable routing; the Highline is designed for internally routed frames only. Next, check your seat tube diameter to ensure compatibility. We offer four different diameters: 27.2, 30.9, 31.6 & 34.9.

Maintenance intervals can vary depending on riding conditions and frequency of use, but as a general guideline, we recommend wiping down the post with a clean rag after every ride and regularly checking the collar and clamp assembly to keep everything running smoothly. For deeper maintenance, we recommend a more complete service around every 150–175 riding hours to maintain optimal performance and long-term reliability.

The Highline 11 features a carbon quill and titanium bolts, which are not available in the new Highline. In the new one, you'll find several updates: an adjustable feature, a shorter insertion length, and a new actuator system that are not present in the Highline 11.
