    Strange creaking

    This has me very confused. I am getting a creaking after about 40-45 minutes of riding. Mostly seated, but after awhile it will creak while standing. If I stop for a few minutes, it will take awhile to start up again.
    I have a Beer BB30 that I have checked many times. I have swapped in a different crankset and pedals. I have swapped out seat and seat post. The rear wheel is an Easton XC1. I cleaned/ lubed the free hub body. I did notice the back plate on free hub body is slightly off, and causes slight wobble in cog when turned. Also tightening the retaining coller, if tightened down, the tool will jam in coller. I am going to try another wheel next. Any other ideas on where to look? It's a cannondale f29 HiMod carbon frame.
    Thanks for any help, I hate noises!!

    Forgot, it seems to creak more with light pedaling. Standing and pedaling hard, it quiets down.

    I'd double check the seatpost/saddle again just in case...

    I would also check your pedals/cleats. I chased a creak down which drove me nuts and it turned out to be my right pedal. Cleaned and lubed it and it's gone.....

    Just to eliminate one other factor, check your pedals. I had both of my XTR pedals come loose and they both creaked when pedaling.

    Check chain ring bolts as well, that was the source of my creak a while back

    I have tried 3 seats and seat posts, no change. I also swapped out chain rings (bolts lubed) I swapped out cranksets with pedals also. And different shoes too.

    Frame welds (or even tubes) in BB area?

    I get creaks from the axle in the rear wheel if the preload get loose.

    I get creaks from the frame when there is a crack....in fact once my frame was warrantied, the creaking went away....go figure.
    I resolve to constantly assert my honest opinion on anything and everything - whether it is requested or not.

    Thanks! I'm going to swap a different rear wheel, and if nothing, have the frame checked

    I had a similar creak. To solve, I removed the seat post, looked for small burrs inside the top of the seat tube that the post might be touching. No burrs, so I applied grease to the area of the seat post that would be inside the frame, then applied grease to the saddle rails, as well as the seatpost binder bolts. Good luck! Bike noises drive me crazy!

    You could start by taking a close look in good light, yourself. And run a fingernail over the surface. A fingernail is pretty good for finding small irregularities like a crack ... or the edge of the sticky tape in a roll.

    If it's happening when you stand and pedal, then it's pretty unlikely to be seatpost/seat causing it, IMO.

    It happens mostly while seated, and pedaling easy, pedaling hard, or standing, and it gets better, or goes away. I have swapped a couple different seat posts, and seats though.

    It could be bottom bracket or rear wheel skewers. Try greasing the inside of the rear drop outs and then tighten the skewers extra tight.

    To clarify: I'm not suggesting a new skewer. I'm saying where the hub makes contact with the inside of the rear drop out maybe the source of the creaking. Put a little grease on the drop out and tighten the skewer very tight.

    I've chased these types of issues for years on several bikes from road to MTB. I have found that it is often a spoke nipple/rim interface. A little lube where the nipple goes through the rim fixes it. You will need to lube them all. Some will say not to do this as it will attract dirt etc., but I've never had a problem in 20 years. Just a thought.

    I'll try the skewer/drop outs. And lube nipples. Not concerned about attracting dirt while troubleshooting. Just want to find it!

    So I tried a couple things at the same(yeah, should have done one at a time). But one of the two seems to have fixed the problem. The insert that is bonded into the BB has a ridge inside on each side. Felt some gouges in it, and the bolts for the beer bb30, had nicks in them also. Might have been it, not sure. The more likely problem was the rear rotor disc bolts were long enough touch on the hub ( on easton hub there is a gap between disc mount and hub. When removing bolts, you can see marks on hub from them rubbing. Also explains why it always takes awhile to start, heat expanding. So far 2 1/2 hours riding, and no noise!!!
