Highline 7 Dropper Seatpost

The Highline 7 is poised to be Crank Brothers' best dropper post yet thanks to its smooth feel, easy installation, and shorter insertion length that allows it to fit a wider range of bikes. Premium Trelleborg seals keep out dirt and grime when you're riding in wet conditions, while the hydraulic IFP cartridge ensures smooth actuation and long-term durability. And to show you how confident Crank Brothers is with their design, the post is backed by a 4-year warranty that lets you shred with confidence.

  • Improve your ride with Crank Bro's flagship dropper post
  • Shorter length sits lower in the frame to fit more bikes
  • Self-contained IFP cartridge offers smooth actuation
  • High-quality seals keep out dust, dirt, and grime
  • Igus glide bearings eliminate side-to-side play
  • Linear actuator gives the post a quick return speed
  • Quick-connect mechanism for easy cable installation
  • Includes Jagwire cable and housing, remote sold separately

I love the smooth lever action

I had a well known hydraulic actuated seat post that came with the bike. They are known for being intolerant to the temperatures below 32 degrees. After a couple trips to the bike shop and a rebuild, it was never right. I went to a Carbon Fiber seatpost for a while because of the hassle. I recently purchased a Highline 7 Dropper Seatpost and was pleasantly surprised how it performed. It is no wonder that it has higher reviews than most other dropper posts. A very good value


Does the post come with a CB remote?

Crankbrothers Highline 3 and 7 does not include a remote lever. The MSRP on this product has been adjusted to give the owner the freedom to choose any remote they prefer. The Highline does require a remote that has the ability to pinch the cable, since the head of the cable feeds from the base of the post.
