i have always had good luck in finding and stopping noise from my bikes, but i have a cinelli starship that i can not get a BB noise to go away, i have tryed grease and plumbers tape, and both......lol...at the beginning of the ride atfer working on it, it has stopped, but always comes back before the ride is over, has anyone ever tryed anything else that might work for this, i hate to sell the bike, but i just can't take much more. it's a campy record BB, thanks for any info, kes
Sure it's the BB?Kerry

With the steps you've taken (can we assume that you torqued it to factory spec? 50 nm for Shimano, 70 nm for Campy), then it's time to start looking elsewhere. What seems like it is tied to the BB may be coming from the seat post, etc. Sometimes things like temperature and humidity can affect noises as well. For chain ring bolts, take them all out and grease the threads, the faces where they contact the CRs, and the CRs where they contact the crank spider arms. Clicks tied to your pedaling can come from the BB (grease all threads in contact with the frame and BB, and torque it to the recommended settings, which can be quite high), the pedals (grease the threads, get some wax etc. on the cleats, grease the bolts into your shoes, squirt some lube into the guts of the pedal machinery if possible), the chain (clean and lube), your seat post and saddle (grease the post, seat post bolts, saddle rails), your bars and stem (grease the stem, stem bolt at both ends, h'bar bolt, and h'bar where it goes through the stem), and your wheels (check for spoke tension, particularly on the rear non drive side, put a drop of lube where each pair of spokes cross). Needless to say, you want to try these things in what seems like the most likely place the noise is coming from, but there are plenty of stories about "I was sure the noise was in the handlebars but it went away when I tightened up the spokes in the rear wheel," so keep trying different things until you have success.

Check your bottle cages, the clearance on the front derailleur, and the cable end for the FD.

I'll vote for working over the Chainring bolts, worked for me(Chorus 10). Campy BBs don't usually have this problem.
many possibilities...C-40

Could also be the pedals, shoes, cleats, chainring bolts, loose rear skewer.

On my C-40 it was the spoke nipples on the rear Ksyrium wheel. Kind of a click on each pedal stroke. A drop of lube on each nipple stopped the noise.

I checked all of the above first, before lubing the nipples.
For me it was Chainrings bolts once and...SGrouts

...rear spoke niples the other time.

Try both!

good (and quiet) luck

I think Kerry provided a good list of things to try. Just to add the the list of "it wasn't what I thought", I spent about 3 weeks earlier this season trying to resolve a grinding/creaking noise I was convinced was coming from the BB. After exhausting all the standard culprits, including wheels, chainring bolts, cranks, pedals, etc., I finally found the problem was my saddle rails which would only creak while pedaling. From now on I'll start with the easy stuff first.
