astroluc said:so, as the title reads, I have this annoying tick coming from the sprocket side of my bottom bracket. It occurs on the down-pedal and more-so under load. I brought it to my LBS and they checked it and greased it up; they said "no prob... just needed to be tightened and lubed"
...get back on the bike and... tick... tick... tick... "dammit"
I was originally scared that it may be bearings, though this is my new ride (05 Cannondale R700), the visit to the LBS asuaged that concern... until I heard it again.
Any thoughts?? Oh, and I am going to bring it back to the shop... I just want some thoughts/ input from those more knowledgable than I in regards to bicycle mechanics. Thanks!
Well, it is not unheard of to have a bottom bracket go bad. I had a very similar problem a few years ago. I went though the list of possible ticking sources. Took of crank arms, lubed and reinstalled. Used a quill stem, so removed, lubed reinstalled. Took off pedals, cleaned lubed and reinstalled. Checked spokes. Looked at saddle rails. Made sure that cable housings were not clicking against each other. I kink of felt that the clicking was coming from the bottom bracket because it would only happen when I stood and cranked hard and only on the right side. I took it to my LBS because I was out of ideas and asked him to pull and look at the bottom bracket. He told me that 9 out of 10 people think that noise such as clicking is coming from the bottom bracket but it usually is not. I told him that I was very familiar with my bike and sensitive to where sounds are coming from. It's a titanium frame Merlin. So, he agrees to pull the bottom bracket for me. Well, he said, what a piece of [censored] that bottom bracket was! You had a bad bearing. A new unit solved the noise.
I just installed a Campy bottom bracket on the bike and used Ti prep on all threaded areas. I also removed the cups from the sealed bearings, and painted the area with teflon goop. Nice and quiet.
If you have gone through all other areas of possible noise, pull the bottom bracket and clean up the threads and reinstall it. Actually, this is a good annual maintenece proceedure that you should do anyway. Inspect that bottom bracket carefully while you have it out. If you have to replace it, it's not all that expensive, depending on what you are using.
