My bike has had an ongoing issue for a couple of months. Most of the time I pedal there is a constant squeaking noise (which I can't pinpoint but seems to be from the chain). This noise only occurs when I'm cycling on the big chainring and completely disappears when I cycle on the small chainring. The noise came back even after I got my bike serviced and changed chain (for general maintenance). The only solution I've found is to wet the chain with a hose before cycling but even then the noise will come back after an hour or so and it's obviously very bad for the chain anyway.

If anyone has any solutions they would be very appreciated.

    Is it really a constant squeak or does it come and go as the pedals turn? Commented Jul 18, 2018 at 20:08

    Consider that when you're on the big chainring the rear derailer is pulled tighter. Of course, on the big ring the chain is also way to the outside, such that it might be rubbing on the front derailer. Commented Jul 18, 2018 at 20:08

    Does the squeaking occur also when you backpedal? Also how does it change when you ride on different rear cogs? Maybe some derailer(s) adjustments would solve the issue.

  • Or maybe the chain is not designed for the number of gears you have.

    Thank you Robert I finally resolved the problem. Ceramic lube did wonders Commented Jul 23, 2018 at 21:08

The most common reason why is your chain squeaking is because there is none or not enough lube on your bike. apply some lube on your chain one drop per rivet and wipe the access lube off (You can choose not to wipe the access lube but it will attract dirt & dust.). A chain with no lube will wear much faster than a chain that is lubed, and it will rust easily too.

  • Concur - water makes the noise go away, because water is acting as a lube. Perhaps the new chain is just as dry as the old one? Or it may be squeaking as the chain touches the chainring teeth.

  • That’s what I think it is as well, but I’ve tried putting lube and the problem is only resolved for about 20 minutes then the noise slowly comes back. Maybe I’m not putting enough but I’m still doing 3 full turns of the chain. Commented Jul 19, 2018 at 10:17
  • Try to listen closely, is the sound coming from the front or the back? Commented Jul 19, 2018 at 14:13
  • It's very hard to tell but I think the back Commented Jul 19, 2018 at 14:47
  • By that, I mean is the squeaking coming from the bottom bracket or the cassette/derailleur. Commented Jul 19, 2018 at 14:47
