The Bike is a 2003 felt s32. I just replaced the bottom bracket a month ago. It rides fine and shifts good. The problem with it is it makes a noise like a ping when the crank is rotated. It only happens uder load either on the trainer or the road. It wont happen if you just pick te bike up and spin the crank. I took it to the lbs today and we spent 15 minutes and couldnt find it. They have a better guy coming in later and i left the bike. any ideas?
Try removing your pedals, apply a thin layer of grease to the threads and replace. I had a similar problem last fall and that fixed it. I thought the sound was coming from the crank.
What pedals and BB? You can try to put Teflon tape on the BB instead of grease, that may get it. Could be your seat rails too…
What kind of bearings are in your back wheel? If they are cartridge bearings, and there is even a minute amount of play in the axle it will make exactly this sound.
Clean and grease your seatpost.
This game is never any fun.
Chainrings, crankbolt, the remainder of the front deraleur cable, bad chain link, bent tooth on chainring.
I’m betting bad chain link for you.
you clearly need to buy a cervelo P3 carbon. The sound will disappear instantly.
Check for a bent of twisted tooth on the chainring or cogs.
The sound is definatly coming from the crank area. It makes the same noise if no on is one the bike and you just rotate the crank. Same as if you dont turn the pedals but just the crank. We tightened the crank bolts and the chainring bolts. If you take an allen wrench and tap you get a real similar sound from the chainring. We checked it out but couldnt find anyting that even might be it.
I think is something to do with the stem and the handlebar! That happened to me and I just took apart the stem and handlebars, cleaned up the area nice and good and put it back together. Guess what???
The noise was still there!
If you just took out and replaced your bb, then I would assume that everything is lubed good and tight there as well as your crank arm bolts (but maybe do a quick check). Also, quickly check you chainring bolts.
In my experience, the next place I’d go is the rear wheel. Pull off the cassette and check the axle/hub bolts to make sure nothing is loose there. Grease the hub and put your cassette back on tight. If that doesn’t solve it, well, go through the progression of other items…
“It wont happen if you just pick te bike up and spin the crank.”
“It makes the same noise if no on is one the bike and you just rotate the crank.”
Which is it?
I meant if you turned the crank without rotating the pedals on the crank arm. I just talked withthe lbs. they took everything apart, lubed it up, taped and banged on things and nothing changed. They said the only other thing they could think of is the rear bearing went dry. its a sealed bearing and spins smooth and quiet so they didnt really think it was that. The checked the bike for a crack but couldnt find one. They did ti by eye though. The chain is fine too.
Have you replaced your chain lately? Could the master link be sticking out a little bit and hitting the front derailleur (or something else)?
They checked the chain and said it was fine. it only made the noise when the right crank arm was between 9 and 12 o’clock. you could rotate it back and forth and it would always be in there but not at the same point in there. Sometimes it would be at 9 and sometiems 12 and sometimes in the middle.
do you have internally routed cables?
I went through this same type noise problem with my P2K
Spent hours as my LBS trying to figure it out.
Ended up being that the plastic casing that threads the cable through the hole inthe bike was a bit loose and would cause a ticking sound.
I had the same sort of thing happening on my bike. It was the rear hub…the bearings needed to be lubed and re-packed.
Hey nos306stang
What kind of BB are you using? Is it one that has that plastic tube between the bearings in side the BB shell? My buddy that own a bike shop had this happen to his bike and it took him forever to find it. And he’s a very good bike mechanic? Check that.
Good luck
Dan…
the bottom bracket is a FSA isis type.
ill check the cables when i get it home
the rear bearings are sealed and running smooth and quiet. they metioned they could be dry but didnt think it was
this is a very very long shot… but it happened to me and sooner or later you will be prepared to try anything…
try taking the bidon cages off and see if it still happens. I once had two mechanics, a store manager and the onwer of a bike chain work on my bike for about 8 hours spread across 4 visits trying to fix a similar noise. It turned out to be that the slight movment in the bottom bracket AREA when under load was moving the bidon cage enough that it would contact the frame. you could also test just moving the whole bottom bracket area laterally to simulate load and see if you still get the noise (which would rule out the branks as being the problem).
