    Niner RDO seatpost...anyone?
    Anyone try this one? Apparently has quite a bit of deflection. Thinking next year's upgrade will include some carbon goodness...I have held out and been fairly anti-carbon...but the times are a changin'!

    I just got one on my Jet RDO. So far, so good. Niner carbon seems to be of excellent quality.

    I used one for half of this season - a bit heavy but on a hardtail the flex really smooths out the chatter / rough sections and has never loosened / caused me any problems to date.

    I also have one on my Jet9 RDO and haven't had a single problem with it in the last 3 months or so. It's a bit harder to tell on a FS bike, but I'd have to say that the deflection is noticeable. I rode a RIP9 with a Thomson post for a couple of months before switching to the Jet9 RDO and RDO post, and, although it's not the greatest comparison, things are smoother.

    I have one on my Jet 9 RDO and one on my Air 9 RDO.

    The flex is very noticable on the HT. Cannot say that i need it on the FS though but hey everything for the looks.

    IMHO you will not be disappointed. If you wanna use it on a non Niner perhaps you should look at the Syntace P6 Hiflex. Same priciple.

    Have one on my Jet 9 RDO and love it. Deflection is noticable(to me) and my LBS promotes the RDO Post over selling me a Thompson! They all use them and think they are the best seat post out there. They do sell others, but they all like the Niner the best.

    Post deflects as much as any other quality carbon post. Compared to my Ritchey, Enve, and Easton. THomsons are rough for sure. I always use carbon.

    Kewl, but I'd like to see their deflection results compared to an eriksen sweetpost, which costs only a little more.

    Interesting. I'm going to be building up a 29er hardtail and maybe I'll have to add something like this to the "build wishlist".

    Besides the Niner post, what are the others worth a look at?

    Question for those running this post on hard tails. How much post are you showing? I know the benefits would start to diminish as the post is pushed in more but wondering to what degree.

    Syntace P6 hiflex. It's supposed to be the same as the niner but with a better clamp that offers more support for the seat rails. Also has a 10 year warranty.

    I have one on the way as we speak. Going to be using it on my Yelli screamy. I'll post a report once I try it.

    Ritchey has one out now too, called the "WCS CARBON FLEXLOGIC LINK". it doesn't say it's specifically for 29ers though.;)

    No, it'll work on anything. I think that it's mostly just Niner owners that are attracted to the Niner-branded post.

    Wait... P6 hiflex isn't german for "stick this in your 29er" ?

    Have Syntace bars and really like them. Considering a Syntace or Niner post. As someone else mentioned. For just a couple of bucks more. You can get a TI post that has a much better chance of lasting for many years.

    Does frame material matter? Seems like a carbon post would be better for AL and carbon. TI post for steel and TI frames?

    Cannondale also has a flex carbon post out as well.
  • 11-13-2012
    talabardio
    Do the ti posts absorb as much as the carbon posts do?
  • 11-14-2012
    92gli
    Syntace has a 10 year warranty and a generous crash replacement policy. Thats good enough for me.

    I would already have an eriksen post if it used the thomson style clamp. I had a bontrager post with the style clamp he uses on one of my bikes a few years ago and bent the ti rails on a nice seat the first day out. Not enough support. Probably not be an issue if you use a seat with solid cro-mo rails.

    Have both, cant tell the difference.

    If your looking for a 31.6 rdo post I've got a brand new moondust one that I'd consider selling.

    I have Syntace P6 HiFlex on my hardtail...love it. Made a pretty big difference coming from stock post. You can definitely feel it flex under there which is what I wanted. The 10 year warranty truth be told is what sold me over the Niner.

    That being said, bought the new RDO handlebar, also a thing of beauty.

    Got the Niner RDO and rode today. Sick. Really works. Back/body noticeably less fatigued after ~1 hour ride. Kills the roots etc. My comparison is to the stock Specy post which I thought flexed a lot. I think its combo of flex AND vib dampening. Anyway, highly recommend. Has a 5 year warranty..who keeps there stuff that long anyway?

    I am in the process of switching to a carbon setpost also. I say process because the seat post keeps on moving on me when I am out on the trail. The LBS has narrowed the problem down to the grease from the previous seatpost needs to be cleaned out more. So make sure you clean out the grease from the previous seatpost.

    As far perfermonce, I did notice the ride was a bit smoother.

    Goood Luck!

    I noticed same with my A9C SS.

    I purchased Hylix carbon seatpost off ebay lasy November have put a 1000 miles on it this year and its held up great! I think I paid about $40 for it including shipping. Great flex to help smooth out the rough stuff on my Niner Air9 HT.

    Does the Niner Carbon Post have the same flex characteristics as the Carbon RDO post?

    It looks like the only difference is the clamp (and the associated lighter weight).
  • 12-26-2012

    Third ride on the RDO...again, definitely more compliant than the stockers aluminum one that came on my bike. I am going to be anal and follow the install directions (I was in a hurry when I got it to ride) by applying a carbon paste but so far it hasn't slipped. I cleaned out the seat tube pretty well but will actually degrease it when I apply the paste. So far, I would say it was worth the price over standard carbon posts out there.

    Nope. It's a different post. The RDO has varying wall thickness to give it more flex. I've had the syntace version for a bit now and it really does help a bit with back fatigue on longer rides.

    Does niner advise using paste ? Syntace actually says to clean out grease and spray a small amount of silicone spray in the seat tube. Carbon paste not recommended because it accelerates wear of the outer finish.

    Anyway... I just installed mine dry and it hasn't moved a bit.

    Those of you riding either the hi-flex or RDO on FS, do you think it's a noticeable difference to a non-flex post?

    I'm looking for a new post for my Spec Epic from the stock and was looking at these vs the Thomson Masterpiece. Thomson is about $40 less (on Amazon) and a wee bit lighter. Not sure if the flex would really do much for a carbon FS?

    Thanks
  • 01-03-2013

    I just don't get how you would notice the small amount of flex/deflection on a FS...I would save my money and just get either a 1) nice al post like a Tompson or 2) a cheaper carbon post.
  • 01-03-2013
    92gli
    Yeah, Like tigeo says - kind of no point. But if you ever build a hardtail, get one ! One of the better bike part buys I've ever made.

    I've read up on these recently, so that's all I can pass on.

    Both are one piece, that is, the head is not bonded to the stem.
    Both flex over the length of the post.
    Weights are comparable
    Niner states the max forward/aft flex of the RDO to be 8mm
    Syntace doesn't say how much forward/aft flex

    One report on the Syntace stated 5mm flex in response to a weight, but didn't say how much the weight was.

    BikeRadar said 1 to 2 cm, but that seems excessive.

    I've seen the Syntace as low as $160, the RDO no lower than $198.

    The syntace (which I have) has a longer bottom perch for the seat rails, which offers better support for ti and carbon rails. Syntace also has a 10 year warranty and a crash replacement deal. I've read the actual carbon layup is identical and done in the same factory as the niner post.

    The syntace 30.9 can be had on amazon for $166 shipped (from speedgoat).
