I had the same problem, and couldn’t figure it out. Eventually I cleaned my chain really well and applied a good drip lubricant to each individual link. You can do it at night, spin the cranks alot to get it in there good, wait till morning and wipe the excess off. Don’t use a spray lube like my LBS uses, didn’t work for me. Takes more time this way, but it’s worth it. If you’ve already tried this or if that doesn’t do it I don’t know.
I scrolled through the post’s(this might be a far cry from where the “ping” is coming from…it’s difficult without the bike in front of me/us)… could it be the computer magnets “pinging” when they cross paths??? some magnets “ping” when they meet…
just a suggestion… FWIW
And the answe ris the rear bearings. I took the bike out today and rode. I noticed that it was periodic and increased with bike speed not crank speed. In fact the crank didnt even have to be moving. I then swapped out my disc wheel and the noise went away. This surprised me since when i had ti ont eh trainer i tried just spinning the back wheel and no noise. guess i never got ti up fast enough. I took it into the lbs again and it was a different guy on it. The others are more atb guys this one is a die hard road guy. he checked ti out and saw where it was makignt he noise and that the bearings where good but dry. I took in the front wheel also.
thanks to all those how helped. I am kind of disapointed tha it was not something exotic like a cable houseing or something.
Have you tried raising your front der up just a tiny bit. It could be rubbing on a tooth.
also, are there marks on the chainstay at all that indicate that the chainrings may be too closse. If you replaced your BB and the spindle was slightly shorter it may cause this problem.
Depending on how loud the ping is, it could be the screws that are holding the cable guide under the BB shell are contacting the BB spindle as it rotates. This could be caused by the new BB’s spindle being thicker than the last one. try backing off the screw off a bit and rotating the cranks.
Finally, snug or not, if the crank arm is slightly off of the isis pattern it can cause this problem. try removing your cranks and re-tightening them with the extractor cap off. keep an eye out to make sure that the splines are lining up correctly.
good luck. I hope this helps.
For future noise diagnosis reference chain link problems do not make noise with every pedal rev, but with every 2-2.5 depending on your chain length and chainring size.
I recently figured out the intermittent squeak I was hearing was my saddle bag rubbing on a seat rail. Sounded exactly like a BB problem.
