I got about 15 miles on my brand new pugs I built. I am getting a weird creaking noise sounds like it's coming from my rear cassette and hub area. I am running a 1x9 with a sram X.0 rear derauleur and a cheaper sram cassette. The wheel were built by QBP and have a xt rear hub. The noise only happens when I am gears 7-9 gears 1-6 it doesn't do it. Just when i'm in the harder gears and putting strain on it. Any ideas??????

First thing I'd check is hanger alignment. Many a noise solved by that little tweak....

Strange though it may sound the hanger sometimes needs some lubrication. The tension put on it by the drivechain can expose a squeek (metal on metal afterall).

 

[justin51]

Well I will check that and lube it. How do you check alignment though I have never done that before thanks.

I saw, cough... heard that happen with a few older C'dales with a box-style rear swingarm: faulty weld made that noise - nothing to see from the outside and it didn't crack. It just made a maddening creaking noise. Such swingarms were replaced under warranty.

If all else (hanger, spoke tension...?) fails, spray WD40 into all the vent holes of the rear triangle (with your dealer as a witness). If that noise is gone after that...

If I'm taking your thought properly, that's only a concern for replaceable hangers, which would have a large flat surface to surface paring. Then, yep, it could make noise. Pug's are replaceable, so unless you meant the threads, it won't help, and I *doubt* the threads would make a noise at all, let alone, one gear combo.

OP, you'll need a hanger alignment gauge, a shop will have one, you can't DIY unless you buy one of these....

Well I am going to move my front wheel with the SS setup on it to the rear and see if the noise goes away. If it does I know it's in the rear wheel setup if it doesn't then it's something to do with the rear deraileur and hanger. Hopefully it's not the frame Surly doesn't have frame issues though so that would be strange!

When I first saw the topic, I got out a number for a divorce lawyer. But then I kept reading.....

FWIW, 81.37% (nfa) of all "creaking" complaints on a bike are ameliorated by a liberal application of grease to the seatpost before insertion. Don't ask me why, it just is. HTH :thumbsup:

Oops.... no opinion.

LOL.... Well I will try that to... My question to you is I wanna mathematical equation on how you got 81.73% just saying!!!!!

Ah, OK. I should have checked the replaceability before spouting useless information. (assuming you meant NOT replaceable )

nfa = "number from ass" or "not f-ing accurate"

But I do see a lot of them....

LOL.... That's I nice random number

 

[justin51]

Well took the BB apart and re checked everything and all looked good so I am back to square one I am lost here have no idea what else to do.

 

[bmike]

have you checked that the cassette is tightened down? i had a problem on a road bike - only 1 wheelset made a certain noise, in a range of gears. tried everything until i isolated the wheel. then took the cassette off, replaced it, tightened it down, and it went away.

 

[justin51]

Yeah i have had it off and re-torqued it.

 

[caminoloco]

If there's no alternative left, do the WD40 test (with a long nozzle tube to get well inside the frame vent holes). I know Surly has no frames issues, but better makes sure now then when the warranty has expired.
Spray liberally and turn the frame as to get the oil in every nook and cranny around the welded spots, if not for dismissing another possible source it'll protect your frame .

Well after countless hours and swear words I have found the problem thanks to my AWESOME wife. It was my chain, I put a old chain on off my 26" FS and problem fixed. Now I can finally sleep!!!!!!!!!
