What is that noise? (Voting)
Postby AUbicycles » Sun Aug 18, 2013 5:00 pm
The noise is associated with pedalling, when I pedal and turn the right foot over I get the sounds "tick tick" which seem to be coming from the front chain-ring. Likewise on the when pushing down on the left, a softer (single) tick sound is audible.
What I know is that the gears are setup well - I re-did them again today and they are extremely smooth, so no rubbing again the front derailleur or halfway between gears front or back. I measure for chain stretch and the chain appears to be perfect - no stretch and I took the chain off, no kinks or 'stuck' links. As the sounds occur in time with pedalling rather that each revolution of the chain, it doesn't seem to be a chain issue.
When I don't pedal, there are no sounds, likewise when I pedal but don't put any pressure it is quite. I normally put pressure in when pedalling, and this is when it happens, the volume increases with the amount of pressure.
I have checked the front chain rings - the sound occurs both on the small and large chain ring - but while there is light wear (black paint has worn) there don't seem to be missing or bent teeth.
The pedals have been checked, nice and tight but I did them again likewise the cranks - it is Shimano Ultegra and bolted on the left side.
The bottom bracket is one part I can't easily get to however I removed the chain and the cranks spun freely - not for a very long time but it didn't feel that the bearings had a problem. When pedalling out of the saddle, the sound remains (I am suggesting that because I have Carbon Fibre road bike that if it is a creak from the saddle, that it would stop).
My obvious next move is to replace the chain however this is a bit of a mystery it seems that I can rule out each item.
Happy for any tips and suggestings, and also taking votes as I have to get this sorted and if I can do it myself will make it the mechanics problem:)

stem bolts, either at steerer or bars, grease, retorque
Front derailleur band on not tight enough
chainring bolts, lube, retighten
bottom bracket, lack of lube or grit, a little play in the shell
rear wheels dust seals, dropouts or freehub
headset bearings or adjustment, in particular crown race not perfectly seated on fork
front wheel dropouts
now go do your homework

But there are so many potential click points - I'd get a drop of oil/grease onto some of those saddle/bars contact points too......

On the saddle, the noise continues out of the saddle... however on my to buy list is 'fibre grip' for the seatpost... but needs to accommpany a torque wrench.

Yes he says that it does, otherwise that's what I would have thought too.trailgumby wrote:Saddle rails in saddle sockets is a regular one for me. Does it make the noise when you pedal out of the saddle?
Bottom bracket is my guess.

Simple solution - strip and rebuild the bike. If the noise doesn't go away, get a new bike.
...real cyclists don't have squeaky chains...

Have to admit that some of the Carbon Fibre paste is still on my 'to buy' list. Considering I have been told specifically NOT to consider buying a new bike, this is a problem to solve.. now where is time when I need it.

Seriously, one-minute job: Loosen stem clamp bolts. Remove top cap. With 8mm allen key, loosen expander plug. With allen key still engaged in plug, tap it firmly to ensure it's seated snug on top of the steerer. Tighten firmly, more than it was. Replace top cap, tighten until no play is felt in the headset (grab a handful of front brake & rock the bike back & forward to test). Tighten stem bolts. Ride with only the sound of the wind in your ears.
After having a fair few TCRs come back with exactly the noise you're describing, and without exception the headset being the source due to creeping expander plugs (the hub possibility was actually on the cheaper Composite models, but still worth mentioning for purposes of investigating & eliminating), every bike I build with a carbon steerer tube gets its expander tightened another 1/4 turn before leaving the workshop. Funnily enough, they seem to shut up after that.

Other time it was a popped plate on the chain, if you ran the chain through your fingers you could feel it but you couldn't really see it (until it was found by feeling..)
I have had it another time using a "shimano" chain joining link which I don't think they make anymore. I think the link was every so slightly wider than the chain and would cause a ticking noise.

Those things were utter poo. Only made for the first year of 7900-series Dura-Ace (late'08-'09). It's not so much that they were wider than the rest of the chain, more that they got longer much faster than the rest did, so they'd ride up on the teeth then drop in at the top of the cassette rotation.jacks1071 wrote:I have had it another time using a "shimano" chain joining link which I don't think they make anymore.
