Why We Like The Highline XC/Gravel Dropper Seatpost

Crank Brothers are expanding their Highline series with the addition of the Highline XC/Gravel Dropper Seatpost to manage steep terrain and fast descents with greater control. The Highline XC/Gravel is equipped with a hydraulic IFP cartridge for smooth actuation and durability, and the two-bolt aluminum head fits most standard bikes with a diameter of 27.2 millimeters. Jagwire's premium cables and housing are included to ensure your dropper post is ready to hit the trail after easy installation.

  • A refined dropper seatpost for XC or gravel bikes
  • T6-series aluminum boosts durability and support on mixed terrain
  • Linear actuator offers a quicker return speed
  • Shorter insertion length fits a wider range of bikes
  • Self-contained IFP hydraulic cartridge provides smooth actuation
  • Includes Jagwire premium cable and housing, remote sold separately

What do you think about this product?



I know this post is designed to clamp at the lever, but is it possible to use a cable clamp and an inline barrel adjuster to use a GRX left lever to actuate it?
