The Fox D.O.S.S. 4" Seatpost finally brings the suspension expertise from Fox into the realm of dropper seatposts. 100mm of travel employs Fox's CTD remote lever, offing three options of travel for Climb, Trail, and Descend. Two separate remote levers make selecting the right mode easier in the heat of the moment. One distinct lever drops the saddle 40mm into the Trail mode, ideal for technical sections where you still need to pedal. A separate lever opens up the full 100mm of travel into Descend mode, to do what the D.O.S.S. post does best, "Drop On Steep…Stuff." The remote lever is mechanically actuated, with a shifter cable and can be mounted left or right and above or below handlebars. 30.9 or 31.6.
Adjustable Drop: 4 inches
Diameter: 30.9mm, 31.6mm
