Highline XC/Gravel brings a dropper to bikes with a 27.2mm seat tube. Its 80mm of travel gets the saddle out of the way on steep descents and technical gravel, then returns quickly for the climb, with a self-contained hydraulic cartridge doing the work.

Highlights

  • 80mm travel in a 27.2mm post for XC and gravel bikes
  • Self-contained IFP hydraulic cartridge
  • Linear actuator for quick return speed
  • Quick-connect mechanism for easy cable installation
  • Internal routing with Jagwire cable and housing
  • 2-bolt head, zero setback, 434g

How it works

The post is controlled by a self-contained IFP hydraulic cartridge, and a linear actuator gives it a quick return speed. Cable installation uses a quick-connect mechanism, and Jagwire cable and housing are supplied. The 7075-T6 aluminium post has a 2-bolt head with zero setback.

Remote & servicing

No remote lever is included. Crankbrothers offers Highline drop-bar and flat-bar remotes separately, so you can match the lever to your cockpit. Crankbrothers publishes every-ride, 150-175 hour and 450 hour maintenance guides for the post, and our workshop can install and service it. Internal routing means the cable runs inside the frame, which is a good job to hand to a mechanic. Fitting is a separate workshop service and is not included in the price.

Crankbrothers' Highline XC/Gravel warranty gives the cartridge a four-year unconditional warranty, covers the post's components (outer body, quill, seat clamp and remote lever hardware) against defects in materials or workmanship for two years, and covers wear parts (dust seals, bearings and keyways) for one year against manufacturing defects. Cover runs from the original purchase date, applies to the original owner with proof of purchase, and excludes overclamping, improper installation, crash or impact damage, wear from missed maintenance and cartridges that have been tampered with. For warranty support, return the product to Tune Cycles and we'll manage the claim with Lusty Industries, Crankbrothers' Australian distributor.
