Using the system is quite easy, just press and hold the lever, and either weight the saddle into the lower positions, or unweight, and let it pop up to the desired location, and then release. Lowering the saddle is extremely easy for the Descender mode since it stops solidly at the bottom, but the Cruiser spot is trickier to find, and does take some practice. Just some mild weight on the saddle is all it takes to control the downward movement. Extending the saddle to the Power mode is simple since it pops upwards to the maximum stop, while the Cruiser takes some slight weighting to control its location. It takes some practice to learn the sweet spot for the Cruiser, but it becomes second nature pretty quickly, and can even be controlled in rough terrain or when moving around on the bike. I have used the infinite adjustable seatposts, and I have found that the 3 positions works just fine, although putting the other posts in the Cruiser range is easier, since there isn’t a notch to have to locate.
What I like about the CP is its simplicity. Being a mechanical system, it has no need for regular maintenance for functionality, it’s reliable, and has great long term durability. The CP didn’t have any stiction issues, and it slid up and down along smoothly, with very little slop felt in the saddle.
It is still a complex piece of engineering within the CP, but the lack of a finicky hydraulic based system, with dampers, oil, seals, and bushings greatly alleviates problems. The CP uses an activation lever (worked via the remote), which pulls on an internal cable, and releases tension on a collet, so the post is free to move. When tension is released, the collet locks into any of the three different slots, which correspond with the Power, Cruiser and Descender positions. An air spring returns the post upwards, and its force or rebound speed is adjustable by varying the air pressure. The collet has a very solid feel, and its outward pressure and tight tolerances help keep the slop and wiggle to a minimum.
The only maintenance I have performed is an occasional dab of some Slick Honey lubricant on the stanchion, and keeping the saddle clamp bolt well lubbed. I checked the air pressure, a number of times, and it never varied. The seat clamp has been creak and squeak free, and it didn’t move if the bolt was clamped down properly. The rough anti-slip zone on the post insertion area helped it from slipping lower, but it would oddly rotate on rare occasions.
The middle Cruiser position was quite handy, and was useful in technical spots and climbs, as it gave you more maneuverability and stability. In addition it worked well on downhills where the slope wasn’t as steep, letting you keep the saddle out of the way, and your center of gravity low. Any time it got steep and deep, or in really ugly terrain, the Descender mode was used, since it allowed maximum movement without any saddle interference, or you could remain seated with a low centering. On occasion I would hit the remote accidentally when I was trying to shift, and vice-versa, due to there close proximity to each other, giving me a somewhat awkward moment.
