Dropper posts are the norm on modern trail bikes, and for a good reason. Being able to lower your center of gravity for descents, technical sections, and corners adds a new level of confidence to your riding. The Marzocchi Transfer Performance Series Dropper Seatpost uses a cable-actuated, internal hydraulic cartridge to provide either 125mm or 150mm of travel for a better trail riding experience. This version is for bikes with external cable routing--bikes without the cable ports required to run an internally-routed dropper. It features a tool-free disconnect at the bottom for easy installation and removal. The low lever force provides consistent actuation throughout the travel, with a return-speed adjustment at the lever. This is essentially a Marzocchi-branded Transfer seatpost, which is not a bad thing at all, as the Fox Transfer has proven to be one of the more reliable dropper post options out there.
