Major creaking!
Put road bike on the trainer for one ride session. Upon road riding again,
the bike was creaking in a major way. It's not the seat as the creaking occurs when standing. Could it just be that the rear tire dropped out a miniscule amt when changing skewers? Thanks, -Hof |

Major creaking!
Per Hoffer:
Could it just be that the rear tire dropped out a miniscule amt when changing skewers? It could any one of many things.... but you probably already know that... My strategy is to pick the low-hanging fruit first. To wit: 1) Check everything to see if anything's loose. 2) Lube wherever it can be lubed. 3) Disassemble, grease, and reassemble: easiest stuff first. Others will undoubtedly list the many parts that could be suspect. But to the beginning of it all, I'd append checking for a frame or crank crack. Twice now I've wasted day-after-day trying to find/fix a creak only to find out the frame had cracked. First one was on my Ellsworth: a faulty weld where the shock connects to the frame. Second one was on my Seven Duo: drive-side dropout - discovered only when it finally separated. Only one (thankfully!) crank failure - but I could have avoided that by finding the crack that was there (and making a funny noise...) long enough for part of the broken-off surface tb weathered/corroded. -- PeteCresswell |

It's worth cleaning up all the niggly little re-entrant joints on the frame and giving them a damn good eyeballing. I had a mystery creak on my previous bike. I gave up and handed it over to the LBS for diagnosis. They called to say they'd found the source of the creak. "Great!" I said. "Not so great" they replied "your frame's cracked". They clean up all bikes they service so the crack, which was at the seat tube / bottom bracket, was no longer obscured by a thin film of oil & dust. Cue a frantic hunt for the warranty card, but that's another story. |
