Noise when applying the pressure.(10 posts)

Noise when applying the pressure.Ingeman
May 27, 2003 2:41 AM
Hi,

Anyone experience a clicking / squeaking noise from crank/rear deraillure when standing out of the saddle. When riding, the noise sounds like it is coming from the rear deraillure area, although as it only occurs when applying extra pressure on the pedals when standing, I would assume it comes from the crank??
I ride ultegra components.

Any thoughts, comments, possible solutions?
thank you
Craig

I had creaking coming from my BB area a few weeks ago. Turns out it was my cleats creaking in my pedals (SPD). I squirted some lube in the inner-workings of the pedals and the creaking stopped.
Same problem here with LS TuscanyNessism

My suggestion is to start a systematic approach of testing, adjusting/replacing components, testing again, ect. until you find the problem.

I've got the same problem with a Tuscany I receintly built up. Click noise from the rear end when sprinting out of the saddle. First I tried a known good rear wheel, tested...No Good, cleaned/adjusted the Dura Ace bottom bracket, tested...NG, new chain...NG, rear derailleur...NG, ect. Thought I had the problem fixed after adjusting the rear dropouts to parallel (adjusting = bending) but the problem came back. Not sure what to try next.

Sorry I can't offer more help. Good luck.

Thank you, I will start the systematic process tonight after work, and hopefully find the noise before this coming w/e's long ride.

cheers

Ed-
Pull the BB completely out of the frame. Clean the shell to the point that you think it can't get any cleaner. Clean the threads on the BB cups. Get some silver or gold, anti-seize lube. (be careful with this stuff! A little goes a long way and don't get it on you! A dab the size of a quarter will turn you into the Silver Surfer by the end of the day!) Wrap the threads of the BB with teflon tape and lube the threads of the shell with the anti-seize. Re-install! Make sure you lube the axle of the BB too! Not with the anti-seize though! Pull the chainring bolts out of the crank and re-lube them as well. Lube the cranks bolts liberally before re-installing them.
This is what I do when installing a BB/crankset in a Ti bike and have never (knock wood) had one come back for BB click!

Ti bikes are prone to BB clicking for some reason. Don't know if it's the alu/Ti interface or just th nature of the beast.
Do you think?Nessism

Merckx-man,

First time I assembled the bb I wrapped the cup threads with teflon tape and greased the bolts/spindle. Second time I took it apart, I faced the bb shell of the frame and greased/taped again. Unfortunately, the noise did not change in the slightest. I would have thought there would be some change to the tone/frequence of the noise if it was comming from the bb.

I'm going to check the rear dropouts again next since this is the only thing that seemed to change the sound at all. I'm starting to think it's internal to the frame in the back. Maybe where the bullet end is welded on at the rear dropout? I've heard LS has had problems with these bullets comming loose? Any wisdom here?

That may be the problem...merckx56

Litespeeds that I have had to warranty have broken either at the dropout(s) or right above the front derailleur clamp sits.
Check all of the welds. There very well may be a crack somewhere, particularly the drops or the chain stays. Or even around the BB shell itself.
Another problem I've heard of is creaking coming from aluminum skewers on Ti frames. The alu is softer than the Ti and just doesn't seem to get a "bite" on the dropout.
If all else fails, call Litespeed! You paid too much $$ for your frame for it to be creaking like an old lady.
Or if it were to "accidentally" fail, you get a new one, right? (insert evil laugh here!)

my creaking litespeed would drive me nuts.colker

it seems the culprit was the seat collar and that horrible alum. insert on the seat tube which litespeed doesn't use anymore (or do they?). threw away there collar and installed a higher quality one (but applied lots of that antiseize stuuf between collar and tube).
lightweight skewers creak, even on steel bikes. try a standard cheap steel skewer on the wheel and see if it betters..
the noise on my obed would drive me nuts. the day i built a steel bike again and experienced silence i promise to never ride titanium again..
the only ti part i have now is a later generation record post. it creaks.

try a solid, steel, boat anchor skewer... if it silences the noise, go from there.

It is fairly common to have clicking noises, but ticks and clicks are very hard to eliminate sometimes. What seems like it is tied to the pedals may be coming from the seat post, etc. Sometimes things like temperature and humidity can affect noises as well. To eliminate chain ring bolts as the problem, take them all out and grease the threads, the faces where they contact the CRs, and the CRs where they contact the crank spider arms. Clicks tied to your pedaling can come from the BB (grease all threads in contact with the frame and BB, and torque it to the recommended settings, which can be quite high), the pedals (grease the threads, get some wax etc. on the cleats, grease the bolts into your shoes, squirt some lube into the guts of the pedal machinery if possible), the chain (clean and lube), your seat post and saddle (grease the post, seat post bolts, saddle rails), your bars and stem (grease the stem, stem bolt at both ends, h'bar bolt, and h'bar where it goes through the stem), and your wheels (check for spoke tension, particularly on the rear non drive side, put a drop of lube where each pair of spokes cross, grease/tighten QRs, tighten cassette lock ring). Needless to say, you want to try these things in what seems like the most likely place the noise is coming from, but there are plenty of stories about "I was sure the noise was in the handlebars but it went away when I tightened up the spokes in the rear wheel," so keep trying different things until you have success.
