Squeakin' when standin'(5 posts)

Squeakin' when standin'NYrider

When I stand in a climb my bottom bracket squeaks - occasionally. This is a fairly new bike (6mos) - I can't tell if it's the crankarm or actually in the bottom bracket. Also - the way they built the bike is such that there's such a small amount of space between the small chainring and the frame that the chain occasionally swipes the frame - is this normal. I'm riding a Bianchi XL EV 2 with Daytona group.

Thanks for any and all help. Cheers.

I'd remove the bottom bracket, clean it, wrap the bb threads with several layers of plumber's teflon tape, grease the shell threads, and reinstall. Works for me for about 6 months, then I need to do it again.

Normal to get some chain slap; not sure where you mean it's touching, though.

Just a thought: have you considered your pedals (cleats) as the squeaking source?

In addition to the suggestion to clean and grease the threads (I've found no benefit from teflon tape) make sure you torque the BB to the proper settings. With Campy Record, this means 70 n-m, and it's unlikely that you would ever tighten it that much without using a torque wrench.

I can't see how the chain could touch your frame. If you mean that the chainring is touching the right chainstay, it should not do this. I think this would be due to the wrong size or improperly installed BB set, or damaged crank or chainring. I hate creaks and am currently try to work one out myself.
