Ok, I've got a steel framed lemond poprad that I've converted into a flat bar commuter. I've got this creak that is driving me nuts. It is very hard to isolate but it happens when I am pedaling hard up a hill. I can sometimes recreate it out of the saddle, but not consistently. It seems like it is coming from the drive side, but I'm not positive.
Things I've done;
- cleaned and re-lubed drive train
- re-greased and re-tightened seat post
- re-tightened rails on the saddle
- tightened chain ring bolts
- re-tightened cassette
- re-greased and re-tightened pedals
- checked for any obvious cracks in the frame
- checked spokes and added a bit more tension
The only thing I haven't done is re-grease the BB. It is a newer Deore groupset with the Hollowtech cups. The BB is pretty much brand new, really not a lot of miles on it. This is my foul weather commuter, but I also had a bad accident this winter and didn't get much riding in. I'm probably going to take the BB out, clean and re-grease the threads and re-install tonight. However, I'm not sure that is it and I'd like a second opinion. Is there something else I should be thinking about that I'm missing? Area I should re-focus on?
