MCR Post Slippage Questions
G'day Everyone
I have been reluctant to post about this because at this stage I'd say the intentions of Niner to sort out this problem is genuine. So I won't be participating in any ranting, raving put downs. Please do the same.
My concern is pretty simple. This problem is driving me mad. Nothing works for more than a couple of hours. Yes, (what ever it is) I've tried it. I have been putting up with it now for a few months. I believe that my second clamp is now fatigued. I will have to use a washing machine hose clamp this Saturday.
I have been assured of a new frame in July. This comes after being told June and I note some members here being told August, so because I am in Australia I feel that I'd be lucky to see this replacement frame in September.
I am curious as to what people know or have heard of this problem being adressed and rectified with the new 09 frames. I am losing confidence in the brand and figure that if I am wasting my time I may as well start extracting my money back from the dealer and go again somewhere else. I don't want to be waiting until goodness knows when to have the same problem because it has not been solved. It seems to be a common problem and happens with SIR9 aswell.
As I say, I do not want to start a pay out thread here. Please choose your words carefully. I have agonised over this situation and the posting of these questions for a while, but have pretty much lost confidence and need to hear what others are thinking. I really just want my loot back at this point.
Your thoughts?

My MCR has the same problem... And I just got a chance to try one of the solutions that were proposed two days ago, and it seems to have worked. What have you tried? I am asking, because, looking at your previous post, you seem to not want to fix the problem using a remedy, but want things to fit perfectly from the start. Is this still true or have you tried all of the remedies that have been proposed?
My thoughts? I think that replacing a frame for a problem that can be solved without any unsightly clamps/stoppers is a waste of resources. Yes, you may be entitled to it, but if there is a solution, why not try that first? That saves all the production waste associated with building you a new frame and your current frame will not contribute to the ever growing wastelands... Again, what have you tried so far? Maybe you actually missed something...

My problem is that these solutions do not work for more than a few hours. You are right that I expect better from the start and think it is rather pathetic that people are expected to put such things in place to rectify a manufacturing blunder. I think I am entitled to finish a ride with the same saddle height I started it with.
I also wonder how I am expected to take a long term view of a frame that simply can not hold it's post for the duration of one single ride.
The point of this thread is to ask what people's views are on the problem being fixed in the new frames and would prefer to focus on that.
What are peoples views on the problem being solved in the new frames? Has anyone got an 09 frame? Has anyone heard anything about this problem being adressed and solved in the new frames?

I see you are in Brisbane like me.
Did you buy your frame via the local distributor??
If so, have you been back to speak with Shannon or Pete??
I cannot believe that they would not sort you out.
I know of probably 5 or 6 people riding Sirs and MCR's locally and have not heard a single complaint from any of them about slipping seatposts.

The local distributor assured me of a new frame and when I enquired recently as to how it was going they acted surprised that I still had a problem. Up until that time I was very happy with their service and accept it is not a defining moment or anything.
I'm happy to hear yourfriends are enjoying their new bikes. Does this mean my post will not slip tomorrow?
As I keep repeating. My question is:

OK I tried to be nice but it seems from your tone that you want to escalate and *****.
My view is that you seem to be in the minority as you are the only one I have heard of with this problem.
My view is also that you don't seem to be willing to listen to any sort of constructive advice as to how you may be able to rectify your situation.
My view is that if you have checked the tolerances of the frame and seatposst and they are correct then it is not a manufacturing fault.
My view is that you need to contact Pete or Shannon or a competent bike mechanic and see if they can work out what the problem actually is.
Shannon and Pete have always gone out of their way to help me and anyone of my mates who have a bike related problem (purchased from them or otherwise).

My tone has been deliberately calm. If you want evidence of an attitude problem try digging up all of your own posts here and on Farkin.OK I tried to be nice but it seems from your tone that you want to escalate and *****.
I have made it perfectly clear that I have tried the remedies given me and have had no success. You are not reading my posts.My view is also that you don't seem to be willing to listen to any sort of constructive advice as to how you may be able to rectify your situation.
I have tried three posts that are easily held in other frames and theyall slip in the Niner. I have measured the seat tube nd it is bigger than my other frames.My view is that if you have checked the tolerances of the frame and seatposst and they are correct then it is not a manufacturing fault.
I've done that, as I clearly stated twicw in this thread.My view is that you need to contact Pete or Shannon or a competent bike mechanic and see if they can work out what the problem actually is.
As I have already stated in this thread, I have had good service with one exception which I clearly stated was not a defining moment.Shannon and Pete have always gone out of their way to help me and anyone of my mates who have a bike related problem (purchased from them or otherwise).
"Your view" TR is the only thing you ever consider, as is your reputation here and elsewhere. Everything you have typed in here (and everywhere else) clearly indicates that you Have not read my posts properly before responding.
Whilst I find you and your attitude rather amusing, I am through entertaining you and remind you of my question to which you obviously have no real answer.
What are peoples views on the problem being solved in the new frames? Has anyone got an 09 frame? Has anyone heard anything about this problem being adressed and solved in the new frames?
Sorry MC.
Obviously cannot help you any more.
Nor can anyone else here it seems.
As I said though.
It does not seem to be an ongoing manufacturing issue.
Seems you just had bad luck.
And repeating this:
And FYI, that must be some sort of wrong sized seat tube given that I have been running a 27.0mm seatpost instead of the recommended 27.2 in my Salsa for over a year now with no slippage whatsoever.
Good luck with your problem though.

Well... I had the same problem on a 2009 MCR. It "seems" to have been fixed by sprinkling some trail dust onto the greasy post. But I don't know for sure yet. If that doesn't help, I'll try some carbon paste, and if that doesn't work, I'll start calling Niner and probably have more to say...
Hello there, Torosc,
Thanks for the reply. I have tried chalking the seat post (similar, I assume to dust?). This worked on a five minute test ride, but not on a long ride. I took a rag and chalk with me a while back and resorted to doing this mid ride when I became sick of overtightening the clamp repeatedly. The post eventually still slipped, even though it was very, very tight.
I have a few steel road bikes and consider them my bikes for life, if I choose to keep them. Tommasini, Cinelli, Repco. I saw this purchase as being the same but just cant see how I could ever be happy riding this frame and seeing it as an "old mate", so to speak, in years to come. I'm glad in a way that carbon paste and chalking has not worked for me because I don't see any success from such as lasting or sufficient.
Thanks for keeping it simple and not bashing the maker or the distributor, who's intentions are not being questioned here by me. I realy wished I'd get an avalanch of warranty claimants that have had their problems solved by a 2009 frame. The truth is more important ofcourse, so I appreciate your reply very much.
Thankyou.

I have a pre '09 SIR9 and ride in Australian conditions. Clamp is a salsa liplock and the post is an Eriksen Ti. Mine slipped. After searching on this forum I tried wrapping a small piece of some very thin paper around the post. Just near clamping point. It slid in about 10mm before the paper started to bunch up. Clamped it up tight and it has never moved since (12 months).
I don't want to get involved in the biffo but MC, before TR asked if you'd been in touch with Shannon and Pete you'd only referred to them as 'the dealer' who could've been anyone OS. Sometimes TR can be pretty blunt but he wasn't this time and was trying to help.
The local dealers are great to deal with. I had some long waits for my frame and fork (4 months) but Tom (the guy I dealt with) and also Pete at other times were very communicative. It seemed the issues were out of the control of our friends in QLD. In the long run it was worth it. It seems that as usual Australia gets the short end of the stick due to volume issues. Yeah it's not good enough, but it's the way it is.

I have had this problem on my MCR. Like MC, I am unable to finish a ride without it slipping. My local shop has spoken with Niner, and they have no problems giving me a replacement frame. Niner has been a fantastic company so far.
That being said, I have solved my problem ! I tried everything trust me, including a few different seat posts. I tried a borrowed Thomson post, and it slipped. I tried another old post I had, it slipped. Someone said to try a longer post ( more surface area making contact with the seat tube). Anyways, I have a small frame. I went out and picked up a new Thompson post in the longest length available. Yes, that sounds silly to use such a long post for a small frame, but that worked. No grease was used. It has not slipped. Just for extra precaution, I wrapped one layer of plumbing/thread tape around the seat post. I really think that the extra length of the seat post has more surface area. I am not an engineer, so I don't know for sure if my theory makes any sense, but so far my problem seems to be behind me.
I do understand how frustrating this can be however. Good luck with either a remedy or getting a replacement frame.

It doesn't seem like the post length would do much since all of the clamping force is at one spot near the top. Unless it just adds some friction. Sure adds a lot of useless weight though.
I did find it odd MC mentioned he wanted a "permanent" solution.
In my opinion, there isn't one. I, like MANY other people, had the post slipping problem on my Cervelo Soloist. It is solved with a proven technique that includes carbon assembly paste. I say it is not permanent, because if/when I remove the post, I need to clean it all off and redo the solution. If you are looking for something you can do once and never again, that may not exist.
Anyone try a thin metal shim? That's what is on the Cervelo - thin brass shim between the post and frame. Carbon paste goes between post and shim and regular grease between shim and frame. Granted on that bike it is because of the odd shape of the tubing, but maybe it would work in this case too?

No it's different.
Take the post out, grab a pinch of dirt and sprinkle it on the greased part of your post. Smear some dirt on the inside of the seat tube as well. Put the post back in.
Surly Constrictor Seatbinder and Bolt will NEVER slip. It isn't chi chi lite or anything like that but it holds better than any other binder I've ever used in 17 years of riding (all between 220 and 280lbs).
If your shop has one of these, ask them to run your seatpost through it. Pretty great little device that has sloved a ton of this sort of thing.

It will make the seatpost not so pretty when you remove it, but it solves the slipping.

Agree that obviously the clamping force is at the top as you mention, however the extra surface area being contacted by the longer post would add some friction. It could just simply be that the Thomson post I ended up with has a tighter tolerance than the other I tried too. I tried carbon paste, it did not work.cycleboy said:It doesn't seem like the post length would do much since all of the clamping force is at one spot near the top. Unless it just adds some friction. Sure adds a lot of useless weight though.
Not to be a smart A$# but I had to laugh about adding " A lot" of useless weight due to the longer post. Really its minimal, especially on a 28lb steel hard tail...

MC, Hud is on the money.
I might be blunt at times with my responses but I think people who know me will tell you that I am actually a pretty good guy.
Also I love taking the p1ss and sometimes people take these comments as being serious and react badly.
The interweb is never conducive to conveying emotions and quite often leads to conflict on forums as a result.
Anyway, good luck with your issue.
Seems to be some good feedback coming from others.
Hopefully some of this will provide a result for you.
I know, I meant the emphasis to be on useless. If there's added weight that isn't serving a real function, it's useless in my way of thinking. Granted in your case it is solving a problem and therefore not truly useless, but useless in terms of having to do that to solve the problem.BP73 said:Not to be a smart A$# but I had to laugh about adding " A lot" of useless weight due to the longer post.

Well shoot, my post started slipping again on my MCR after I've started riding it a lot more. Before I try some of the methods to solve this, can somebody answer a question?
When the seatpost is in the frame, should it be a completely snug fit? On my bike, you can feel a bit of fore and aft play in the post when you tug on it back and forth. Of course, that's with the clamp loosened. Is this normal, or is this what is causing the problem?
I would think if the post didn't have that play, it wouldn't be able to wiggle its way loose.

Mcr Seat Post Slippage Issues
Just got my 09 MCR in the first production run and am having the same issues with slippage of the seat post. Haven't been able to ride much because of trying to solve the post issue.
I am lucky to make it through a ride with out having to adjust the post 2 x at minimum.
I have tried /bought two new Thompson posts and MOST of the above noted suggestions. With no success.
I feel for the amount of money that bikes are now going for that putting dirt on the post to get it to stay in place should not be a solution or blue lock tite.
I contacted niner and they are always nice and respond quickly but have not had been able to recommend an appropriate fix. This seems to be a production problem i would guess??
I dont know where to go from here but I do not enjoy the bike anymore and am considering
an alternate frame. Will have my LBS contact niner.
