    2013 Altitude 750 -- creaking noises

    I've got a 2013 Altitude 750 (aluminum version) that's about a month old and has about 60 hours of trail use. It's got quite a bit of creaking and groaning going on when there's some exertion. In saddle, out of saddle, you name it.

    Tried tightening what I can...

    I tend to think that the crank arms are the culprit, but they're pretty snug. But it's hard to locate precisely. Of course it could be a combination of things....

    Others with similar experience?

    The bike rides really well, but i'm a bit picky and i don't like squeaky bikes.

    I have the same thing with my 2012 Slayer, and my buddy does with his 2011 Slayer as well. Spent all last weekend completely disassembling the cranks, chainrings, pedals, BB, and main suspension bushings. Everything got a clean, regrease, and then properly torqued back together. Sadly, creaking was still there. Usually I find that cleaning the chainrings and lightly greasing where they meet the crank spider solves the issue on other bikes, but not this.

    We had a real wet year one year and had a creaking problem on my hardtail, I took out my chain ring bolts and greaed them which worked for me.

    Same experience on my wife's 730...
    The noise seems to be located around the upper link!!
    After disassembling all the rear linkage, bushings... Cleaning an torqued (following RM prescription) Noise is still here.
    I don't know if there some relation but the rear back of the bike is clearly not align with the front end. There 's a difference nof nearly 1/2 inch between the two wheels!!!!

    Okay... ...i dug into the problem a bit.

    1) shock pivots (new style pivot bushings made by Fox) were squeaking. Added a drop of Phil Tenacious Oil all 4 corners and gone.

    2) crank arm bolt (right side on the RaceFace cranks) needed to be really really tightened down hard. This took care of the rest of it.

    Now the bike is quiet.

    The only other issue i've had was that rear wheel spokes loosened up almost immediately. That was easy enough to take care of.

    Note - i ride the bike a lot; on chunky trails 6 days/week. I haven't had a completely trouble-free bike EVER, and this RM Altitude seems to be doing pretty well overall. And it rides great.

    Thanks for the notes & suggestions.

    Are the wheels properly dished?

    The 142 rear axel can make a good amount of noise if not greased. It is one of the only metal to metal contacts on the bike. Put a good amount of grease on the axel and reinsert, then clean any of the additional grease from the outside of the threads. Creaks can be very hard to chase at times. When my axel is making noise, it sounds like it is coming from the pivot hardware on the shocks.

    creaking noises are gone !!!
    I just put an amount of grease between the frame and Iguss bushing's washers of the upper rocker.
    There another source of noise on this frame : the alloy cable stop under the bottom bracket. When suspension is in action, tension of the cables makes the internal cable stop insert moving; then it hits the frame in a tic-tic noise; which can be compare to a creaking noise due to the resonance...
    Maybe not an issue on carbon frames

    Was looking at getting the 730, you guys happy with them other than the creaking noises? I have 2 29ers but I think I want something still fast but to get that quicker responsive steering back. Don't get me wrong I love my 29ers just some days I would like to carve the corners harder and the 29 just doesn't do it as well as smaller tired bikes.

    The 750 that i have is getting more ride time than my other bike. Definitely rides better (for me) than any 29er I've been on.

    Very happy with it.

    I just got the 730 last week, sweet ride. I find the rock shoc rear shock is better than the fox on my 2012 element 70 msl. It's a keeper, I'm in the process of switching everything over to X0.

    Just thought I would post this as it might save someone else some time.

    The shop I work for got a size run of Altitude 730 demo bikes a few months back and now that I've worked on a fair number of them I have found that the number one spot that seems to creak is at the rearmost pivots (near the rear dropouts). The little o-rings provided by Rocky Mountain to keep out contaminants seem to do little to prevent the fine dust our local trails largely consist of at the moment from getting between the bushings and causing a pretty irritating creak. Disassembly, cleaning, and greasing of these pivots has resolved the creaking issue in every instance so far, although the creaks have come back on at least one bike as contaminants made their way into the bushings again. Luckily these pivots are easy to service, so it hasn't been too much of a hassle.

    I would try this first before blowing every pivot apart.

    I just ordered this bike. I'm glad this isn't an long term issue. It sounds like most are pleased with this bike and brand. Very excited.

    No creaking or squeaks here. I have over 200 miles on my bike. However, my Monarch makes a squishing noise but it has nothing to do with the bike.

    Do any of you with noises put a light film of grease on your bushings? I have. Maybe its a maintenance issue.

    My week old Alt 750 started squeaking,took apart the upper link and greased metal to metal tourqed up and all is quite now.
    It was fun putting it back together because i forget to put the shock on first!
    Awsome bike though!

    For the time I have o my bike, the only thing I found was the need to grease the shock bolts. I was riding 30 hours a week xc and dh rain or shine.

    Weird to hear about all these creaking issues.. I've put nearly 1100 miles on my slayer in the last 8 months and it is completely creak free. I do keep it clean and greased but thats about it... and I dont loc tite the suspension bolts.. I keep them extremely clean and greased.

    The Slayer doesn't use RM's ABC pivots.

    Seem to have cured my minor creaking, the lower shock mount bolt was pretty dry stock from the shop.

    With so many pivots there are so many possible sources for creaks, one source that I only discovered after long searching (and taking apart a lot of other parts), were the shifter cables leaving the diagonal frame tube (below the bracket). There's a metal piece through which the cables leave the frame tube, by lubing the outside of the cables in this spot I temporarily solve this problem (to be repeated once in a while).

    But now over to the good stuff: Rocky Mountain finally found out that their ACB-bearings need regular lubrication, so their 2015 models (at least the Thunderbolt) will have 4 grease ports. I know this since I tested a proto (provided to RM to our enduroteam) of these links for some months about a year ago:

    2013 Altitude 750  -- creaking noises-untitled.jpg

    This worked really well as expected , but I had to return the proto after some months so others could do some real life testing as well.
    As I had some spare Turner grease zerks (the old pressfit type) I converted my own link into a 'Rocky Mountain meets Turner' link :

    While lubricating using a Turner (Dualco) grease gun:

    They now advertise it:

    I hope this is a usefull contribution to the thread for all my fellow creak-hunters out there

    Well, I started this thread over a year ago....

    This spring I sold the Altitude 750 and got a Bronson. No squeaks or creaks on the Bronson ever; none. And it is a lot stiffer chassis than the Altitude. Also, for those who ride uphill, there is no comparison: The Bronson climbs much much better than the Altitude. I would tend to believe there are a lot more people moving from the Altitude to the Bronson than the other way around....

    The notion that Altitude owners should have to deal with squeaking/creaking/noisy linkages is a real shame.

    The idea of the IGUS bushings may have seemed good, but it's clear that there was not enough "real world testing" on RM's part. And the back end of the Altitude has way too many linkages/bolts/bushings/O-Rings/washers to be stiff and trouble-free in my opinion.

    The Altitude does a lot of things right. They were pretty early to get a really good geometry out there for a 650b bike. I'd like to think that RM will make a few evolutionary corrections to make it as good as it could be.

    Fully understand Uberstein selling the Altitude and switching to Santa Cruz.
    Being a Santa Cruz owner myself (Tallboy C and Tallboy LTc) as well as being a industrial maintenance professional, I prefer the SC build quality and maintainability over the RM products.

    However: also being a RM enduro team member riding an Altitude I will (have to) keep riding this bike, which makes good fun once you've conquered the creak monster since on the trails it's a real nice bike.

    When you say you converted the Turner grease zerks, did you have to do any modifications to get it to fit in the RM frame or did it fit without any mods? What do the Turner grease zerks go for?

    Ok. Thanks for posting the pro/ghetto mod though! An interesting idea for those that need regular bushing maintenance. IME after 2 years and ~3,000 my bushings are all still good. Now that I've jinxed myself I wont be surprised if during my annual winter maintenance I'll hear I need new bushings!

    Are these grease ports something you can retrofit to a pre-2015 Rocky? I have a 2014 Altitude.

    Subscribing. I'm in process of chasing down a very loud and frequent cracking sound that happens when linkage is cycled under load on a RM Altitude 2013 frame. The bike isn't mine. So far I have cleaned and reassembled all IGUS pivots with a thin film of grease, as they had wear marks on all surfaces (including aluminum parts BOTH sides of a bushing). The noise remained.

    The grease fitting mod pictured above is nice, sounds like it's a real time saver.

    I have struggled for a year trying to figure out what was making my altitude creak and squeak so horribly. I tried everything on this thread with no relief. Greasing the pre-15 ABC bushings doesn't work and is a really bad idea if you're not going to clean and re grease them regularly. My LBS couldn't diagnose the noise either. I was about to buy a new frame because the noise is so f**king absurdly loud and annoying, but I FINALLY fixed the issue.


    1st: If you are having constant squeaking/creaking noise when your suspension cycles check the metal insert under the bottom bracket where the rear derailleur cable passes through the frame. Pull out the cable and clean the insert with a Q tip. When dirt & water gets into this spot the cable ferrules move around inside the insert and cause terrible frame noise. I've found that using a metal ferrule instead of a plastic one helps a lot. I replaced the cable housing for the rear derailleur at this section and made it slightly longer so that there is more cable hanging underneath the bottom bracket and this keeps the ferrule from rotating as much and making so much noise. I also put a small glob of glue from a glue gun over this spot so dust would stop getting in there! The glue can be removed really easily when you need to do service.

    2nd: If you are having loud cracking/creaking noises that can be felt in the frame when your suspension is cycling you should try tightening all the pivots (except for the huge one above the bottom bracket) to exactly 9 newton meters and use loctite! The big one is 11 NM. If cracking persists replace your bushings. I had to replace my bushings and the replacements where MUCH MUCH tighter fitting than the ones that came with the bike.

    Try this before you curse your altitude frame and send it to the grave!

    this is completely wrong.

    9 newton meters on all the pivots except for the one big pivot above the bottom bracket. 11 NM on the big one.

    Are the swingarm's main pivot bearings bonded in or dit you press them in dry or with grease? My experience is this is another source of noise: the bearings officially should be bonded with medium-strength Loctite (638 is the Euro number). Put them in dry and things will get noisy.

    I haven't had issues with my bearings at all so I haven't touched them. I checked them not too long ago and they were still pretty smooth after 1 and 1/2 years of riding. Can you describe the frame noise that the bearings are causing for you?
