On trails with technical descents, grinding climbs, and rolling technical sections, Specialized's Command Post BlackLite ensures you're always in the best position to rule the terrain. It controls your seat height with the flick of a lever so you can maintain the flow at all times. There are 3 positions to choose from: up for climbing; down for jumping and steep descents; and a middle height when you need to pedal, but you want extra maneuverability too. The seatpost is sealed for reliability, and is controlled by a lever that mounts to your handlebars and connects with a cable.
So some comment that is loses air while riding. I have never experienced that in the 12 months I have owned it. I would say of all the dropper posts i have owned this one has needed the least amount of maintenance of all of them. i would say yearly to pull it apart grease the internals and replace the seals. They are all bound to eventually have problems and lack of maintenance only makes this happen faster. The major advantages to this over other posts is the mechanical lock out. when other posts fail on the trail you are stuck with a post in the down position. With this post you can pull it up and lock it in one of the 3 positions and continue your ride.
Bottom LineYes, I would recommend this to a friend
