    Creaky Smash

    Hey All.. any advice?

    Bike is now almost one year old.. its been ridden about 150 days..

    I have pulled BB and cleaned and regreased, took fork off and cleaned and regreased headset.. greased seat post..

    Suggestions.. most noisy while climbing..

    GG is backed up on service so I thought I would try to handle myself...

    I chased a creak for 6 months, seat rails....

    Im presuming you're seated when climbing?

    EDIT: or remove handlebar from stem, regrease lightly and reassemble to torque specs

    I will try those suggestions.. however, I do climb mostly seated, but when I stand and pedal, its creaks even worse so thinking it is not the seat rails...

    1) Shock bushings. Pull em out, put a thin film of antiseize on all surfaces, then reassemble.

    2) Check the pivot bolts at the seat to chain stay pivot. Remove, lightly grease threads, then retorque, if the bolt spins then there's your creak.

    and though I'm sure you went through the rule outs:

    Same noise in all gears
    Same noise seated or standing
    Same noise suspension locked or unlocked
    Swapped in different pedals
    Checked all pivots and torque to specs
    Moved Geo headset to different position and/or reinstalled with anti seize
    Removed bars, cleaned bar center and stem, greased bolts, reinstalled

    I just love creaks!

    My last one was on the Pistola, took me forever to find it ... shock bushings.

    PS: The ill fated BB, always blamed, but rarely at fault. Bluntly put, threaded BB's don't creak unless they loose. When they go bad they feel gritty, grindy. So yeah, it's not your BB.

    Check the chainring too, especially if you have Race Face cranks. I've had their lockring work loose, so that the chainring itself was moving around. Given that you said the noise increases when standing up, that makes sense (you're putting more force on the drivetrain then).

    I had a spacer under my stem crack and creak. It took me a long time to find it.

    Always go for the bottom bracket first and replace. My smash was creaking and it was the bottom bracket.

    Mine was the front shock bushings on my hazard. A little grease coating and re-torque to spec fixed it.

    So I have been chasing a creak for awhile. Thought it was seat rails and all the other usual suspects. Mine appears to be the section of carbon on the top tube in front of seat triangle. Does that make sense? What's weird is it mostly does it while climbing and it doesn't do it all the time. Temperature and humidity seem to affect it. I tried to reproduce for a video and it wouldn't do it. If I hold the bike in one place and push on the frame below the seat post I can hear it and feel it in frame just above the water bottle holder. Anyone else seen/heard this? I was going to contact GG but left town for work for awhile. It creaks while sitting and standing.

    Take the pivots apart per an above comment. Spin each bearing a few times to re-distribute the grease in the bearing. Then you can feel if they need replaced. Once done, clean the surfaces, re-grease and re-install.

    If all else fails, fill your bath with oil, put whole bike in, turn every 30mins, every 24hrs take it out and ride 10kms (no downhills, just walk those), after a week the annoying noise should be gone, replace brake pads and rotors.
    Thank me later.

    I'm actually reading the thread with interest - have a Smash on order so hoping I won't need to do much creak tracking...(I know it's going to happen at some point with every bike...)

    If you'd like, if it's a size 3, S and I can pick it up for you, she can test ride it for a couple of months and only send it to you when we're sure it's not creaking.

    Great! Which bearings, and what did you do to stop the noise?

    What about the pivot bearings? Were they toast or was there build up between the pivots?

    I may have found a simple solution to the headset noise.

    My chainstay to seatstay pivot was also a source of creak. I took everything off and the last thing I checked was that pivot on the non drive side. When I turned the bolt it chirped/creaked LOUD. I knew I had finally found the source.

    Currently chasing a new one.

    I just had another creak develop on a ride yesterday - turned out to be a loose chainstay/seatstay pivot bolt on the drive side. Glad I stopped during the climb to investigate. Good reminder to check the torque on the pivots regularly, although it is very possible that I failed to torque it back down when I was tracking down my previous noise that ended up being the front shock bushings. All quiet now so life is good.

    Funny I had that bolt come loose twice. Just cleaned everything and torqued to spec - letís see if it stays put now

    I thought my BB was trashed. I cleaned and greased, re assembled, creak stayed away for one ride and was back. It seems like it's the plastic bushing on the chain ring side is where the noise is coming from.

    I had creak from my ISCG 05 bash guard. I could actually replicate the creak by pushing on the bash guard. With the iscg mount that is on the revved frame it might be a good idea to clean that area behind the mount.
