I'm singing the bottom bracket blues.(7 posts)

I'm singing the bottom bracket blues.Juanmoretime

I have a Shimano bb7700 bottom bracket with only a little over 1,000 miles on it. When I put a lot of pressure on the cranks, going into the wind or climbing it starts to creak on the power stroke of the left crank only. Should I try to regrease it and adjust the cups or is it cooked? BTW, it's only been ridden in some light rain once or twice. Lastly, if is done for, should I try it again or go for the Ulegra? From what I understand is a better bottom bracket. Lets here from the voices of experience.

Thank you,

Juan

I went through the same thing. Remove it, wrap the threads several times with teflon (plumber's) tape, and reinstall. I'll bet that make it go away.

Although I don't think that this directly applies to your situation, I recently solved a creaking "bottom bracket problem" by lubing the contact points between spokes of my rear wheel. It took me a full week to figure it out(with some help from my wife). I greased the saddle rails, seatpost, removed the bottom bracket (greased and plumbers taped it, lubed the pedals......through a long process of elimination it became apparent that I was not even close to what the eal probelm was.
Good luck with your search!

...I had a creak that was on the power stroke of the non-drive side crank that I thought was the BB. Took it out, regreased, and reinstalled...creak still there. Swapped out rear wheel with the rear wheel of my wife's bike...creak still there. Swapped out front wheel...creak gone. Lubed the nipples of the front wheel and the creak disappeared.

Arrived home from work pulled the bottom bracket, greased the bearings and teflon taped the cups and took it for a ride. The creak is gone. Thank you everyone for your input.
I like to thank everyone too!pa rider

Mine started to creak saturday and used most everyone's advice for troubleshooting.

I had a strip crank arm replaced and relube and teflon my bottom bracket. Like colnago40 said I found three chainring bolts loose. I relube my stem and wheel skewers. If it's still creaking I'm lubing the spokes on these ksyrium wheels.

I got caught in the rain alot this pass two weeks, so I wouldn't throw out the option of lubing the spokes.

Boy, you do get alot of information on this site.

Thanks guys,
