    2010 hifi deluxe creak?

    Posting to see if anyone else has run into this. I have had this a little over a month now but when I first got it on the second ride (about 25miles on the bike) it started developing a creak when the rear suspension would start going through it's travel. Only on the smaller rolling bumps where it was constantly moving and not really on the bigger hits, but constant..

    From the best I can tell it is coming from the forward shock mount, but it's hard to hear where when you're riding, and another weird thing is that is seems to only start after riding for a few minutes....maybe after getting heated up in the sun? Since it takes a few miles to get going it is hard to reproduce in the shop and they don't see anything wrong. I have taken it in twice and they cannot see anything, they have tightened all the bolts to the specified torque, checked the BB/cranks, but sure enough on the trail it starts again.

    I'm pretty sure it's the rear shock pivot somewhere because it makes the loud creaking regardless if I'm pedaling, standing, turning..whatever, as long as the shock is moving it's doing it. I have also ruled out the seat post or rails as well, because trail side I will stop and push down on the top tube and reproduce the sound....just cannot in the shop, must be a temperature thing after sitting in the car or my apartments AC.

    Also, it does not sound like a high pitched squeak like the shock needs to be serviced either, its a very audible creak...kinda like when the GF rig EBB is acting up (Rig owners you know...) but it's coming from the shock joint somewhere...

    Anyone else having this issue?? Suggestions..

    Thanks in advance,

    You could judiciously drip some triflow at the shock pivot point to see if that resolves the issue.

    Check the torque on all of the pivots.

    Shop has already checked all the pivot bolts for proper torque....twice.

    I might try the triflow, but I want to come to the shop with something. Maybe have them service and lube all the pivots, but it's a new bike and should not be having issues like this. I just hope it's not a frame issue.

    My suspension doesn't creak...I don't think...but I've experiencing a LOT of creaking from the general area of my cranks and bottom bracket, mainly on climbs (when pressure is on the cranks).

    I checked all the chainring bolts—they're torqued down tight. And I'm 99% sure there is nothing wrong with the BB bearings (they're external and seem perfectly fine).

    So maybe I need to check the suspension again?

    check your headset

    I had a similar creak in my HiFi Pro 2010, I suspected my crankset also, but just on a hunch I pulled my headset apart and noticed some kind of shavings or grit on the fork's steerer tube. I wiped it and the bearings clean, coated everything with fresh grease and now it's quiet.
    Not saying that's your problem, but it's one more thing to help with troubleshooting.

    Good luck, those creaks are maddening.

    The BB/Crank was the shops first guess. The shop installed the cranks wrong at first and it destroyed the BB, so SRAM sent another one out and it got installed fine. But that was not the issue and the creaking continued. It will creak even when not pedaling or even with my feet off the pedals, just when the suspension is moving.....so who knows.

    Yea, but a few seconds may solve the problem and you would be done with it. That would also aid in determining if that's where the noise was coming from. Just because something is new doesn't mean it's perfect out of the store, many things I buy require a little tweaking here and there to make them right and I sure don't want to be running back to the store all the time without doing a little investigation myself.

    Anyway, that would be my approach but I understand everyone is different. Good luck in isolating the problem.

    Be sure not to lube any of the pivots that use a bushing. They do not need any lube or grease and it is not recommended.

    I don't think a teflon lube will be a problem regardless of what is recommended. The same thing is said about fork stanchions, and I have been using triflow on those for many years without issue.

    You definitely don't want to use grease.

    Lubing them with anything will create more noise than it will solve.

    Yes, and I have been lubing things on my bike that I "wasn't supposed to" with various products for over 20 years with no ill effect.

    I have used wd-40 on cables where it enters the housing, triflow on pivots and stanchions, and I even wash my bike with the water hose and a nozzle. Oh, the horror.

    If it were me, I would drop some lube on there. Others obviously disagree, but a lot of people have been using lube on pivots for a long time. The arguments against are that it attracts dirt and may eventually cause damage to the bushings. I haven't had any problems, so guess I will continue to live on the edge.

    Thank you. I was anxiously awaiting your approval.

    mrilo:
    It seems several people have had this problem for the first few miles of riding and the noise went away once the bushings wore in. Another potential is the air can is not threaded all the way in, or has dry threads. You could have the shop double check the shock.

    Thanks for all the advice guys. I will try some of the suggestions, it's just frustrating when I cannot reproduce in the shop. They are a good LBS and I'm pretty sure they will take care of me once we get to the bottom of it. They told me to bring it in right after a ride so they can hear it.....

    The creaking on my hifi is from the air can not being threaded tight.

    check your rear skewer.

    i know it sounds funny but seriously check it. i had a creaking sound on my 2010 hifi pro last fall and it was driving me nuts. i checked everything to no avail. was on a ride with a buddy of mine that used to wrench on the usa cycling squad and he said "man tighten your rear skewer, im tired of listening to that thing" sure enough, that fixed it.

    hope it helps

    So, I think I can rule out the Air can looks like it was tightened down properly. As for cracks, it has been inspected by my shop twice and by me with a bright light over and over and I cannot see anything noticeable... unless it's a hairline crack behind a bolt I just cannot see.

    As for the skewer, it pretty tight, Maybe the ABP joints need tightening....not sure. I'll let you guys know when I get to the bottom of this.. Thanks for the input so far..

    same here on the creak....

    Hey all -
    Same thing here....last week I picked up my 2011 hifi deluxe and this weekend went out on my first ride.... the entire ride it was doing exactly what mrilo said and I to am 99% sure it is the rear shock area. I also thought about the headset and rear skewer but it really does seems like the shock. As soon as I got home I put some triflow on the pivot points. I wiped them dry/clean and got back on for a quick spin around my house... it was a quiet as can be and seems to have done the trick. I have to go out for a longer ride to see but the triflow on the pivot points looks like it took care of everything. That being said.....I put it on VERY lightly and then wiped every bit of excess off. I'll let you know after my next ride this week.

    My buddy owns the shop I got my ride from and he also used to work for trek....he told me the lube approach is fine as long as you aren't going nuts on the bike.

    Check your air cans. Only way to check is to let all the air out of it. Then tighten it by hand. Very diificult to tighten it while it has air. That and my cracked seatpost were my problems.

    Still have not found the cause of this, I just cannot find a time to bring it to the shop after a ride to reproduce the issue. Every time I take it in after it's been sitting in the house or garage it will not creak. But like clock work about 10 minutes into a ride... then creak, creak.

    Another interesting thing... I ride 95% of the time with PP on (RP2) but while on a ride last week I noticed that it was being extra creaky and much louder and I then I realized I had turned off PP and was rolling full open. When I switched PP back on the creak went back to it's usual self... not sure what that means but it's worth mentioning.

    I still need to look into the triflow....where are you guys putting it? On the forward shock mount bolts??

    Just have not been riding the hifi much and have been on the HT most of the time. I'd much rather be out on the trails and not taking the bike apart and to the shop, so when the weather turns south here soon and all the trails are closed hopefully I will have the time to get to the bottom of this.

    Took mine into the LBS for a creaking that was driving me nuts. They found it in 2 seconds. Cable housing for the rear derailleur had been pulled too tight. They moved it around and got rid of the creaking.

    De-gas your airshock, tighten in, air it up and see if it goes away. It will be very hard to turn the air can with air in it.

    loosen shock mounting bolts, squirt a little lube around the spacers work, the shock a few times and re-torque the bolts..

    I don't have creaking, but instead squeaking with shock motion on my RF. I pump a coupel of cc's of fork oil into the shock (after decompressing), reset sag/pressure and it goes away every time. So for me it must be a seal squeak or internal one- but either way it works.

    Follow up here and I think I have gotten to the bottom of this. I tried two of the fixes that were suggested so I am not sure exactly what it was or a combination but either way the creak is gone.

    First I let all the air out of the shock and was finally able to twist the air can and tighten it down, not a lot of movement but enough to get a few mm's of twist. Second I removed the forward mounting bolt to maybe re-torque it and possible put some tri flow on it as suggested above. What I found was interesting, the bolt had flakes of blue loc-tite all over it smeared around like it had been trapped in the joint. Looking at the theaded end I noticed a lot of the loc-tite was missing so maybe somehow it worked its way into the joint?? Anyway, cleaned off the entire bolt, got a cotton stick and cleaned the inside of the shock mount, put a thin layer of grease on the bolt, applied fresh loc-tite on the threads and torqued it back down....

    So, after all that took it out for about 24 miles yesterday and now NO creak!! Hopefully it will stay that way. Thanks again for all the input.

    update on my creak...

    Hey everyone -

    A few rides in after a simple "lube job" my bike is as quiet as a church mouse. I decided to take the conservative approach first and just drop a tiny bit of lube around the bolts and pivot points....all good.

    Basically I just dropped a little in, wiped the excess off, and rode away...all good.

    The creak on my RF drove me nuts--turned out to be the rear derailleur cable housing was rubbing right on the chainstay pivot causing the creak. Love the easy ones.

    Okay...I originally thought the creaking in my HiFi Pro was the BB. No way---I've disassembled, cleaned, lubed, anti-seized, and torqued everything down there...I even disassembled and cleaned and re-greased my bearings!

    It still creaks.

    So I made sure my chainring bolts are tight, swapped out my pedals...

    It still creaks.

    So now after reading all the other posts in this thread, I'm thinking it's got to be the rear shock mounting bolts, the chainstay pivot, or the air can...so I'm gonna try all those.

    Just one question: what the heck is the air can? LOL I have an RP23 (or 24), it's definitely an air shock. So I read to let all the air out of the shock, but exactly how do I "tighten the air can?"

    Thanks,
    Scott

    Followup...

    I just went out and sprayed bit of Teflon lube on all the suspension pivot points and shock mount bolts.

    Then I tightened the living sh*t out of the rear skewer.

    Then I went for a short ride...creaking was not as bad...but it was still there. (Grrr...)

    Then I stood next to the bike, grabbed the brake, then pulled on the handlebar while I pushed against the top-center of the frame. That made it creak (lateral force). I could make it creak at will doing that: tick, tick, tick, tick.

    So about the only things I have left to try are...

    - remove, clean, lightly lube and reinstall/torque ALL suspension pivot bolts and shock mount bolts

    - tighten the air can

    ...and then if that doesn't help...I'm down to going over the entire frame with a magnifying glass and bright light looking for any cracks.

    This is THE most difficult bike-mechanical issue I've ever dealt with in my life, bar none.

    Geez...I'm ready to kill myself.

    I took the bike to my LBS, just for the he'll of it. I figured they might find something I couldn't.

    As soon as they heard the creaking, they all said "Sounds like a cracked frame." Great, just what I need. they said they'd look it over and see if they could find the crack.

    A few hours later, they called and said they didn't find any cracks, and that the problem was a loose air canister on the rear shock (RP23). WOOHOO! Problem solved!

    Except it wasn't.

    I brought the bike home, went for a ride...and it STILL creaks like crazy.


    The guy at the LBS even said he lubed and tightened the shock mounting bolts, checked the bushings.

    SOMETHING on that damned bike is creaking...and I seem no closer to finding it...

    Not sure what to do now. The problem is that the creaking---regardless of where the source is----is being transmitted throughout the whole frame of the bike. So it can't be found simply by listening carefully. You'll go mad if you try that, because you'll swear the creaking is coming from EVERYWHERE at once!

    Replace the bushings. They are dirt cheap. Take out the seatpost and clean and lube it, pull the headset and lube that as well. Lube the area where the rear wheel axle contacts the frame.

    Did you try greasing the rear skewer/axle too? My Deluxe stopped creaking. I basically did everything else you did SWriverstone, minus the obsessive BB stuff, plus greasing my skewer. It sounded similar to a squeak I had on my hardtail, but seemed more like it was coming from the suspension on the HiFi. So I did the same thing with the HiFi as I did with the HT, which was like you just going over everything...clean, lube, tighten. I'm not sure what worked on either bike exactly but the creaking is gone in the HiFi, and the skewer is the only real difference I saw from your approach. Just used the basic parktool grease lightly on the skewer rod, cleaned the dropouts, tightened down real hard. Not sure if maybe the ABP has something to do with it all?

    Now I still have rear brake turkey warble, but I'm living with that for now at least.
