dev null Posted February 17, 2016 Posted February 17, 2016 Peoples I need some advice. I have a 26er BMC Fourstroke 02, Alu frame. This bike creaks like an old chair when I pedal. At first I thought it was the bottom bracket. Replaced that, but it creaks still. So, I did some static investigations. It seems that when I put down power on the pedals, the creaking comes from the rear wheel skewer. What can I do to fix it? I also have a rattle that I can't trace yet. Any ideas. Rattles when I ride the rough stuff. I already looked for loose bolts and all that obvious stuff. Let me know your thoughts.
BaGearA Posted February 17, 2016 Posted February 17, 2016 put some grease on the skewer for the rattle check the seat tube or headset for sand or broken parts posibly

dev null Posted February 17, 2016 Author Posted February 17, 2016 Check your water bottle bolts Already done. Too me it sound as if the rattle comes from around the rear shock area, but I already checked all the pivot bolts etc.
David Marshall Posted February 17, 2016 Posted February 17, 2016 Already done. Too me it sound as if the rattle comes from around the rear shock area, but I already checked all the pivot bolts etc.Check the shock hardware before you tighten the bolts. Sit on the rear wheel and lift the bike by the saddle. You will feel play as a slight knock. Don't tighten the bolts beyond the recommended torque. Also check cables and brake hoses for rattles - especially if you have internal routing.
Ghost Rider X Posted February 17, 2016 Posted February 17, 2016 My carbon Trek Madone is permanently parked on my indoor trainer. It had a terrible creak at the seat post.I took the whole bike apart and tighten and greased everything. Headset. Seat post. Bb. Crank bolts. Stem. Seat clamp. But still the creak was there.... Finally I removed the fork and sprayed some "spookpis" into the frame with some cool drink straws as an extension. Went through the head tube and the hole where the top tube joins the head tube. Sprayed where the seat tube joins the head tube from the inside. (Only way to reach there). Very quite now!!!!!!Tjoepstil!!!!!!!

This tip helped me find the rattle. On casual inspection one don't see it, but sitting on the wheel, and moving the saddle I could hear the mechanical play. The problem seems to be at the top bushing where the rear shock mount into the arm. The bushing is just plain worn out. I will probably need to replace the bushing on both sides. Blimey, and my front wheel bearings are also running rough. Money, money, money.
Patchelicious Posted February 18, 2016 Posted February 18, 2016 Money spent on creaks and rattles is an investment in your own sanity.
DJR Posted February 18, 2016 Posted February 18, 2016 Money spent on creaks and rattles is an investment in your own sanity.Tell me about it! I was hesitant to open this thread for fear of jinxing myself again so shortly after I managed to silence my road bike after many months of struggling. At least I managed to kill all the noises that my own somewhat deaf ears can hear. My riding buddy tells me there is still a squeak somewhere, but it is at too high a pitch for me to hear. That'll keep him off my back wheel. And if he wants peace an quiet, he'll have to pay me to fix it!
Bomberman Posted February 18, 2016 Posted February 18, 2016 Spent a lot of randelas and time on up grading my drive train, was so chaft with myself....then it started . Stripped it all off and to find my BB is shot. We will never win.
AlanD Posted February 18, 2016 Posted February 18, 2016 Creaks,squeeks, grinds, rattles..etc..are the inevitable burden of this sport. They drive me crazy amd takes over your life when you have it. I have become somewhat of a master at identifying these noises on my bike as i am relentless in finding and elimating it. Recently i had a squeek that i eventually traced down to a loose brake cable rubbing on the rear of the suspension frame after lubricating eveny pivot and checking every bolt. Add that to your search criteria.
Milosh Posted February 18, 2016 Posted February 18, 2016 I have similar , A new BB helped , but still there GRRRR Pivot brushes i am told , busy replacing so will see and let you know.
Jewbacca Posted February 18, 2016 Posted February 18, 2016 Thankfully I am pretty much stone deaf in one ear and completely oblivious to all the small noises and creaks. The big ones I can hear but fixing those is obvious. I really don't envy you guys who are subject to such fine mastery of sound management!
