Make the pinging stop!!!(14 posts)

Make the pinging stop!!!niteschaos
Jun 2, 2003 5:10 PM
I have a new crank, new chain, and new cassette. When I pedal I hear a pinging noise at every rpm and every load, not just when I stand up to crank on it. There is pinging even when there isn't any interference with the derailers. I have pedals that don't have sealed bearing and have 3000 miles on them and the bottom bracket could be loose, but other than that I don't know what to check. It's driving me mad.

More info?
Did the noise start after you got all the new stuff or did you get all the new stuff tring to fix the noise?
What kind of shifting system/drivetrain do you have?
Does it make the noise on a repair stand (every load even no load)?
When did the noise first start?
It did this before and after I got everything replaced.niteschaos

I had worn out my chain and was hoping that replacing it and the rear cassette, which was a must at the time, would also take care of the noise. It only happens when I'm pedaling. The last time I had a loose bottom bracket I could feel it as well as hear it, this I only hear. I don't think it's the spokes because it pings even at high rpm on level ground, but not when I'm gliding. I'm riding a Felt F75 with 3000 miles and 105 drivetrain.

Borrow a buddys Wheelset and see if the sound goes away!
When all else fails-take his whole bike!;)

Have a friend who got a Litespeed. It was "pinging". She was not sure what it was. When we rode this weekend, she asked me what I thought. It turned out it was her rear brake cable slapping against the top tube with every small bump in the road. I told her to take it to the shop and have them install three of the rubber donuts around the cable and the noise would go away.

try sticking lube in between spokesbenja15

I know spokes creeking together can make a pining noise and some lube where they cross can fix it

otherwise see if bottom bracket is loose and just work through all the other stuff that could be messed up, pinging noised are hard to track down

make sure you check it is not your seat, or seatpost

give it a good lubing. Don't bother wiping too much of it off...take it out for a few miles nice and sloppy. Work it through all the gears. I have found *some* new chains to need this in order to get rid of all sorts of odd noises. This may be all it needs.
If it happens at the same spot in every pedal rotation...Matno

chances are really high that it's one of your pedals or your BB. I've had both problems happen to me (just noticed the pedal clicking last week - DOH!) and the solutions are simple. Tighten (and remove and grease) your BB first. If that doesn't take care of it, replace the pedals. Try swapping them out first, just to make sure, but with the description you gave, those are by far the most likely options.

You mentioned that the "pinging" is at every RPM and every load. Question. Does it "ping" at the same crank location every time? If so, check that the front deraileur cable is not clipping the crank on the revolution. Also, check that the chainring bolts aren't rubbing against the chain stay, though I doubt this is the problem since the crank is new.

Check everything thouroughly, and isolate possible areas. Remove the chain from the rings and rest it on the BB shell. Spin the cranks and listen for noises. If you put your ear against the saddle. If all is good, you should only hear a whoosh. If the bearings are going and/or their rolling surfaces are wearing, the noise will be clicky or grindy (I invent works). You can do the same test with the rear wheel by removing the wheel and reinserting it with the chain off the cog set. Check the front wheel the same way. If you couldn'y find any problems with the bike on the stand, but the "pinging" still persists while riding, then see if you can borrow a wheelset, cranks, and/or pedals from a friend or shop for a test ride. If you still have noises, then change out the BB.

one other possibility: if you have Mavic Open pro rims, it could be the old "Open Pro click" that you are hearing -- switch out your wheels w/ someone else to rule out/confirm the noise is with the wheels.

A+

try pedalling with one foot (actually unclip it)then alternate. I did this once to discover a clicking pedal. Just a suggestion to help narrow it down.

recently solved my creaking4bykn
Jun 3, 2003 12:58 PM
I've had this creaking when ever I pedaled. Tried the usual, chainring bolts, cranks loose, pedals, bottom bracket, seat rails, seat post, took all off one at a time and greased and tightened. No fix. I finally thought of my seatpost clamp, removed it, greased it and now my ride is dead silent.

So why does ti seem to transmit sound so efficiently?

I would never have guessed it, but I had to clean all my cable stops. Corrosion and dirt had worked its way in between the metal cable stops and the cable and the slighest turning of the bike when under a load caused the creaking. Bet you can't guess how many things I overhauled before I came to that conclusion.
