    Jet 9 RDO creaking while pedaling

    Over approximately the last month my V1 Jet 9 RDO has been creaking while pedaling. Initially it started while climbing but then progressed to where it was happening whenever I was pedaling. If I stop pedaling, the creaking goes away.

    Initially I thought it was the bottom bracket and had the local Niner dealer install a new PF30 BB. The dealer also identified that I was missing a pivot bolt for the rear suspension and got it replaced by Niner. During this process they noticed that some of the rear suspension bearing were shot, so they are also being replaced by Niner. In the interim they greased them up and I rode this weekend. It was also the first time riding with the new bottom bracket. The bike didn't creak for the first 17 miles, but then it started again. Again, it was only when pedaling and worse when I was using bigger cogs in the rear. Without pedaling the creaking didn't occur.

    I should be getting the bearings replaced this week. Hopefully it solves the issues but I thinking that if it is the suspension bearings, shouldn't it be creaking without pedaling too?

    Anyone else noticed this on a Jet 9 RDO?

    Jet 9 RDO creaking while pedaling

    I would check the torque on ur pedals, cranks, and rear hub. I had a similar issue and didn't trace to a loose hub until some shifting issues developed and I noticed the hub was loose. Also use assembly compound on the threads of all the above things.

    What about standing vs Sitting pedaling.

    It's doing it sitting and standing as far as I can tell, but again only when pedaling. I think the pedals are fine (Shimano XTR's). My cleats creak a bit but that is a different noise altogether.

    I did wonder a little about the rear hub as the potential cause and mentioned it to the dealer today when I dropped the bike back off. The wheel set is also pretty new (Enve AM with DT240 hubs) and the Niner dealer had to put different end caps on the hubs to adapt them to the V1 RDO (they were 142 and they adapted to 135). I also put on a new cassette (SRAM XO) on this wheel set.

    I'm not too experienced with building or maintain wheels/hubs, so not exactly sure what to check on the hub.

    There has been quite a few people asking the same question as you & even on other bikes & over have of them have found the rear Skewer to loose.

    Re: Jet 9 RDO creaking while pedaling

    The other common source of creaking is loose front chainring bolts.

    I had some creaking occur last year and simply tightened the rear wheel and this fixed it. No such luck this time around.

    That was one of the first things I checked and they were ok.

    The part I finding strange was how it was fine for 17 miles yesterday and then started again and continued for the next 18 miles. Maybe the grease they put on the bearings helped but still doesn't explain why creaking is only occurring with pedaling.

    Sounds a lot like the PF30 creaking. A remedy is to use TFE paste on the PF30 and that should help tighten the fit. Rear skewer that is not tight can make a lot of noise too.

    Check the skewers as others suggested. I've had the exact same issue with my Jet, thinking it was the bearings that needed to be cleaned/greased.

    I'm waiting to get the bike back from the shop - they are putting the new bearings in. However, should this not fix it, I wanted to clarify what I'm supposed to do with the rear skewer.

    I have the 135mm axle. Mine just sort of screws in, doesn't have the typical quick release lever, but rather you just tighten it by hand.

    Am I supposed to just check if it is tight? Or is there something more I need to do. Sorry for the noob question but just a little confused on this one.

    Here is a picture of my rear wheel. One the other side of the wheel (left side of the skewer which you can see) is the handle that you use to tighten the wheel down.

    Sounds like you have a DTSwiss RWS skewer? Yes, those are designed to be tightened tight! On the handle side, between the black part of the handle and the washer thing (it's not really a washer but I can't think of that it is called) squirt a little triflow or wd-40 in between so that it tightens smoothly.

    Yes, that is the type of skewer. I'll try the lube on that part as soon as I get the bike back. I've got a lot of riding planned this weekend. Heading to Brown County in Indiana to ride the IMBA epic, so that should give it a good test.

    Did they replace all of the suspension pivot bearings? If not, that's what I'd check next.

    That's hopefully underway as I write this. They were waiting for them to come in from Niner. However with all te good responses on this thread, I'll have a few other things to check if the creaking returns whie riding n Brown County this weekend.

    One thing with the creaking... Everyone can hear me coming, but then they are surprised that its a Niner making all that noise!

    Man, I have been chasing down a bad creak for 2 months now, we tried about everything. Finally, last week, we figured out it was the cassette. It was installed dry and was creaking against the freehub body. Dead silent now.

    Was your creaking worse in the larger rear cogs? That is something I have noticed.

    I had the cassette installed by Art's when I ordered the wheel set, so haven't taken it off or checked it. I'll add it to the list if the creak is not resolved.

    I had a hard time determining this. It was worse when I was doing heavy climbing which meant I was in the larger cogs but I was never sure if it was the extra load or the fact that I was in a larger cog.

    Very good suggestions in here - thanks. My Jet 9 RDO is 6 mos old (2013) and started creaking like mad under uneven load - heavy side to side work with the suspension in an active state was the worst. It reminded me of my first generation Blur who's pivots needed rebuilding every 20 or so rides. It also had that creaky BB aspect to it but I could not tell.

    Anyhow, I pulled the rear wheel off and noticed slight play in the derailleur hanger. It was not really loose but still a bit of movement was easy to see. When I pulled the hanger off, there was a lot of grime in between it and the frame interface. There is no way the hanger was perfectly flush with that muck.

    So, I cleaned all this up put a thick bit of grease between the layers and put her back together with a tight axle. (There is a very slight chance the axle was not tight enough, originally.) The first ride tonight seems to indicate that the issue is gone. I'll report back if it is short lived.

    Interesting about the rear derailleur hanger - if my creaking persists I'll have to check that.

    I got my bike back from the shop tonight. They got all the rear suspension bearing replaced. Sounds like my old ones were completely shot and binding up. Anyone else have this on a Jet 9 RDO after two seasons?

    They also took the cassette off, cleaned and lubed it.

    I took it up and down the driveway a few times and it was fine but the real test will be Saturday at Brown County. We'll see...

    Not trying to hijack, but I get creaking in my '13 Jet RDO when only sitting and pedaling. Tightened the post and seat, and still get creaking. Any suggestions here???

    Try lubing the hell out of the rear thru-axle.

    Take it out and make sure it is clean, lube the threads, the axle, and all the surfaces that come in contact with the frame. Lube the hub end caps where they touch the frame in the dropouts. I use Phil Wood's Water Proof Grease. Unfortunately at least at first the grease will hold some dirt but after a ride or two it will be easy to clean up as long as you don't over do the grease.

    Then when you reattach the rear wheel, turn the thru-axle tight! Don't break the flanges on the handle but it needs to be super tight. Then the clamping part should be moderately firm but not super tight as you can break the thru-axle inside the hub and that will be a different level of problems.

    This has fixed a bunch of my creaking problems that I could not figure out. I went through several BBs and checked suspension bearings, derailluer hangers, seat posts... you name it. The thru-axle was unfortunately the last thing I thought of...

    I've known a few other brands that seem to have this rear thru-axle issue too.

    Jet rdo, did all your things as well.

    Dérailleur hanger as well. Bit of dust gets in there and away it goes- you can tell if you grab the derailleur and give it a little twist and it creaks.

    I removed the deraileur from the hanger, cleaned and lubed, then removed the hanger from the frame, put t all back together and bobs your uncle!

    Ok, some good news. I got out for a long ride at the awesome Brown County trail system in Southern Indiana today. After four hours of riding - no creaking!

    It looks like it was likely the suspension bearings. The shop did check my cassette as well and put some extra lube on it, but considering the bearing were in such bad shape that still seems to be the more likely culprit.

    The question is - should the bearings be replaced regularly then? Maybe each season?

    I replace them when needed, which tends to be at about 16 months so far. For the most part I don't ride in wet conditions so that probably helps a lot. Although the last set of lower pivot bearings I went through seemed to be right after several surprisingly deep stream crossings (in which case my bb was shot as well).

    Unfortunateky, You can't assume it's the bearings because a decent mechanic would have done a thorough frame cleanup at the time - remove clean , degrease etc . Done that before, thought it was an upper pivot bearing, but it came back in a ride or 2, but the act of removing a rear wheel and tightening things while I was at it meant I couldn't tell what the fix was.

    Creaks can be massively frustrating!

    My jet 9 has developed a knocking sound when pedaling??? Driving me crazy.

    Everything feels smooth nothing feels wrong…Just a knock or tick sound every pedal stroke. It seems to be coming from the left side

    My replacement J9RDO developed a pretty nasty creaking while pedaling under load while climbing. I checked/tightened the BB cups into the adaptors, the chainring bolts, the pedals, the crank arms and the pivots. None of these stopped the creaking.

    After reading this I tried cleaning and re-lubing the 12/142 thru axle interface. This did not solve it. Then I removed the rear der. hanger and it had some debris from the manufacturing that had to be cleaned. I did this and then re-greased the interface of the this part and tightened the hanger to spec. This immediately stopped the creaking. hopefully this will be last of the noise.

    You know sram does not recommending re-using the PF30 cup right? as in, you remove them and they are done. That could cause some noise too I would imagine.

    Yep, I was rebuilding the bike this past Friday to ride over the long weekend. I had to reuse the sram adaptors that I had, but I added some green loctite. This actually enabled me to be able to tighten the BB cups to a much higher torque than the first time I pressed them in. I hope this der. hanger being loose and not mating to the frame tightly is the culprit. If so, I am just about dialed in on the replacement frame.

    Creaking victory

    SO glad I found this thread. Like previous posters, I had severe, continuous, annoying and embarrassing creaking during high-torque, low cadence pedaling in the big cogs. I'd already cleaned and greased the cassette/freehub interface, so I knew that wasn't the problem.

    After reading this thread, the first thing I did was check the hanger for looseness, and was disappointed to find it was tight. I took it off anyway and found the mating surfaces between the hanger and the frame were colored brown. Clearly some very fine dust taken up residence in there. I cleaned the surfaces and coated them with Teflon anti-seize.

    While I was at it, I also disassembled and cleaned all the pivots. There was some contamination in there but nothing severe. The bearings were all in good condition.

    I took her for a test spin today and hallelujah, problem solved- mostly. I still have some miscellaneous squeak/creaks during high-torque, low cadence pedaling, but it's 80% better (I think the residual creaking is from another, yet-to-be discovered source). I can't say whether the improvement is from the pivots or the hanger since I cleaned them both at the same time but if you're having creaking issues it's worth trying and not hard to do. BTW Niner is now recommending that pivot bolts be tightened to 10 Nm (the older bolts say 6).
    I dreamed I ate a 10 lb marshmallow. When I awoke, my pillow was gone.

    Always seems like the BB gets blamed initially for creeks. Gotta say I've never found that as the problem. Not saying it can't be, just not in my experience. Today's bikes just seem to be creek amplifiers which makes it even more annoying.

    What I've found, most of which have been mentioned. If anything has anything additional please add to the list.

    • XX Cassette - never had the problem before 10 speed SRAM. Showing up a lot recently
    • Chainring bolt - Recently noticed it in the big ring but not the small ring
    • Skewers - they are loose or have grit in them
    • Pedals/Cleats - usually only one side creeks so easy to diagnose
    • Headset - Never had this myself but friends bikes have had creeks there.
    • Saddle/post - Easy to figure out as it still creeks when you stop pedaling or stop when you stand up.
    • Spokes - Once had a road bike where the spokes rubbed against each other and creeked. Little lube there and it stopped.
    • Derailleur Hanger - Never had that as an issue but adding since I see it in the thread.
    • Housing Ferules. This one drove me crazy for a while. Seems like nylon ferules would fix this so I kind of wonder why I had this issue.

    Jet 9 Bearings ahead of BB

    I'm looking at the second replacement of the lower, forward bearings (in front of the BB) on my Jet 9 in as many years. The other bearings seem to last longer - at least they haven't seized. The lower front bearings froze to the point where it loosened the pinch bolts and caused a creak under heavy torque. Re-tightening the bolt (red one) fixed the creak, but not the cause of the problem. I'm awaiting delivery of yet another pair of enduro bearings. The low and forward position of these bearings on Niners seems to make them very vulnerable to environmental damage. For as little as they move through the suspension travel, I wonder if bushings here wouldn't be more appropriate (perhaps bushings with grease nipples). I suppose bushings aren't very fashionable though.

    under-load creaking - pivot bearings guilty - jet9 al

    Hit everything mentioned previously mentioned for weeks. Finally resorted to the most time-consuming repair and pulled all the pivot bearings. The bearings themselves were fine, it was their seating in the frame. I don't know if they were too tight or too loose (probably too tight as I kept tightening them and this alleviated the problem temporarily), or just needed lube but I cleaned out all the frame seats, lightly greased and rebuilt more or less to torque specs. That did the trick - no more creaking.

    My creak was the bottom bracket. Disassembled, cleaned, re packed with some grease and topped it off with a squirt of lubricating oil on the the "bearings(black plastic)"....silent now

    do you used the Shimano one? or Sram?

    Hey Kuttermax, is your Niner still creek free? I've been working with the identical sounding problem for over a year.

    For the most part I've had a very good season with my Jet 9 RDO. I have made a number of big changes to the bike though. At the start of the season I swapped out my White Bros Loop for the Rockshox RB-1. I also replaced my XX1 crank with a Quarq XX1 Powermeter. Later in the season I replaced the Fox RP23 with a Fox DPS Evol, including their newer mounting hardware and bushings. My local mechanic helped with a number of the installs and he always checks the bike over when I have it in. I haven't had any significant ongoing creaking issues this year but I do spread out the wear between my two Niners (I also have a RIP 9 RDO). For those of you looking to put an upgrade on the Jet 9 RDO, the DPS Evol is really cool. I've noticed a lot more mid-stroke support since making the change.

    That being said, there is no question that full suspension bikes require a fair bit of maintenance to keep running in tip top form. I took my RIP 9 RDO to a trip to Colorado this year and after a hard week of riding that included some shallow stream crossings it needed a lot of work including replacement of the suspension bearings. In contrast, my Jet 9 RDO has seen mainly dry trails.

    Niner is going to be launching their new racing bike very soon so it will be interesting to see what tweaks they make to the design. The various generations of the Jet 9 RDO definitely addressed many of the early design issues. Some of the aftermarket bottom bracket designs, such as the Praxis Designs Conversion, have also helped fix some troublesome issues for people.
