Creaking Campy BB

[litespeedguy]

Have Campy chorus components- when honking hard uphill I hear a "creaking sound" in the BB area; my mechanic has tightened the BB & cranks & it's OK for awhile but then the sound retrurns when I'm torgueing.

Anybody have ideas on how to remedy this.

My LBS uses teflon tape to help secure bottom brackets. Have you tried that?

I had the same problem with my CHORUS bb and after awhile it just stopped turning all together.
When I took it out it was just a mess of metal shavings and bearings everywhere.
CAMPAGNOLO bb systems are not so well known (in my experience) to last so long...

A great alternative for Campy users is the Phil Wood bottom prackets made in the USA -- five year warranty, I think. Steel, ti, and oversize ti spindle versions, rings aloww you to adjust chain line plus or minus 5 mm on most frames, great bearings that are really sealed.

Your LBS should have performed a more thorough check and procedure instead of just torqueing. How long has it been since you got the BB serviced?

Phil Woods are a little pricey although the company vouch for them to last at least 22,000 kms. Another alternative but cost a little less than Phil Woods is an FSA with Campy spline and taper. But its a 103mm and not the 102 campy spec. but it does work.

These BB creaks can just as easily be the result of the frame/BB-shell quirk, in which case it's often merely a pain in the rear noise. In fact, I know I've read that the phenomenon tends to be a touch more common with Ti frames than with others -- even with high-end, otherwise superb bikes. It may just be an annoyance, the kind of thing that teflon tape and a little luck can cure.

Or it could be the BB innards after all -- how long you've been using the thing, or the time since its last checkup, could be a clue. Might be worth a look.
