    Strengths:    no sideways movement, infinite adjustment, sturdy, stylish and great value.

    Weaknesses:    Remote control was fiddly to get right.

    Bottom Line:   
    I've had mine for a summer and winter season, it has been used and neglected over that time. First the negative, I found that (it may be common to other seatpost remotes) finding somewhere on my bars that was easy access, allowed the cable to run true and avoided the brakes and shifters took some time. I also found that the remote cable was sensitive to excessive mud. The power available to pull back the lever to the lock position was poor and therefore any stickiness in the cable was a pain.
    I solved all that by including a spring between the cable stop and the lever (threading it over the remote cable) It works superbly now.
    Apart from that the post feels solid, no movement at all when locked, easy to keep clean and lubricated, takes massive punishment from my not insignificant frame and keeps on trucking.

    Forward saddle mount


    Bottom Line:   
    Just got back from my first 5 hour + ride using this seat post and I can't find enough good things to say about it.
    I paid $167 shipped to my door, and this post was definitely worth that price.
    I had been looking at dropper posts for about 4 months but was repeatedly turned off by the high cost.
    Having found this one I have no regrets so far.

    Before i get too far in, let me state that this is the first dropper post I have ever used, so this is not really a comparison to other makes/models.

    It is very beefy, and seems well built.
    Both the release and remote are made from machined aluminum, so they should hold up to some trail abuse.
    I'm not sure what the name for it is, but the saddle mount has fine teeth on the top and bottom allowing for lots of fine angle, saddle adjustments.

    So far I have not experienced any issues with the post getting "stuck" in the dropped position, which is common with the KS posts.

    The design of this post makes it so that the saddle mount is forward of the post.
    This may be an issue for riders who prefer their seat farther back of the center of the post. I have heard of people mounting the DNM seatpost backwards to compensate for this. However I cannot speak to the reliability of this method as it likely puts forces of the riders weight in directions that the post was not designed for.
    I mounted mine in the designed direction and my saddle is pretty well centered on the mount. So I suspect the majority of riders will not have an issue with this.

    The only other issue you might have is that the seatpost is too high when fully extended.
    When I installed mine, I had to insert it all the way into the seat tube (to the min height line on the DNM post) to be in a proper pedaling height when fully extended. Users with shorter legs or taller seat tubes, may have to go without using the full length adjustment, or consider cutting down the seat tube. I'm 5'11" if that helps at all.

    Some concerns I have, based on my own research on dropper posts:

    1. Staying in upright position - (the KS seatpost seems to have multiple reviews where the users mention that the post no longer stays in the upright position but rather acts like a suspension seat post, and to fix you have to send the post into KS to be serviced. The reason I have this concern is that the DNM post seems to be very similar in appearance to the KS, however I have not experienced any such problems)

    2. Possible seatpost damage from Bicycle repair stand - (LBS, and lots of home builders use repair stands that hold the bike by the seatpost. I have heard that this can cause internal damage to dropper posts, and cause them to no longer function. I build this bike myself, and as it was my first build I took it into my LBS to have it looked over to make sure I did everything right. As they took it back I was chatting up the LBS owner and casually looked back at my bike and cringed as I thought I saw that he had put it in the stand using the adjustable post, but he actually raised the entire post from the seatpost clamp and used the lower seatpost to put in the repair stand. This made me think that they are aware of the issues, but maybe not all LBS's are?)

    3. Dirt and debris in the release mechanism - It's seems common that dropper post owners cover the release mechanism with an old tube section, to prevent dirt getting into it and fouling things up. I have not had any issues yet, but will be doing the same just to be safe.

    Those are the only concerns I have, and hopefully I have explained where those concerns come from.
    If I have any of those concerns become an actual problem (or if any other issues arise) I will post an updated review to shed light on those issues. But if you don't see another review here from me, then consider my concerns a non issue, and consider this a product I would reccomend.
