Why We Like The Highline 3 Dropper Seatpost
Though we´ve had great luck with the Highline Dropper Post in the past, Crank Brothers made a number of improvements to this 3rd generation to boost performance and reliability even further. This Highline 3 is their lower-cost option, but it uses much of the same technology as the more expensive Highline 7. The difference lies in a simpler hydraulic cartridge that omits the internal floating piston, and a standard 2-bolt head rather than the quick-connect head found on the Highline 7.
