Bottom Bracket Noise (what's it probably mean?)
I have been waiting for my bb tools to come in for a couple weeks now. If they don't come in by Friday...
The bb had started clicking (not squeaking or creaking, and I pinpointed the sound with the chain off so it is definitely bb) infrequently, and I have had to ride it for my short commute. It has since gotten more frequent, but still unpredictable (not on every pedal stroke). Typically, the left side clicks near the bottom of the stroke, and the right side echoes just after. The right side doesn't always chime in, but it seems to more often than not.
My question is: What does this type of sound usually indicate? is the bb likely toast (it is is old, I have never seen the inside of it)? is it probably just out of adjustment? If I really get the itch to ride tomorrow on a rare nice day, will I kill it? It doesn't feel rough when I pedal, just makes an annoying click.
Thanks for input, wondering if I can ride w/o making things way worse, and if I need to just plan on replacing the bb in any case. I hope to not have to replace thing, seeing as others have told me I would probably not be able to get the drive (fixed) side off myself and the LBS would have to then get involved...I'm starting to hope it pours all day tomorrow.
