Resurrecting this thread since I'm having a lot of noise coming from the BB area (Ultegra external BB).
Here is a quote from Mark Hickey on this subject that I found in another thread (http://groups.google.com/group/rec.b...350e00c345ac):
"Teflon tape is basically a VERY thin sheet of lubricant. It takes up
very, very little room, and I recommend it highly for the installation
of bottom brackets.
1) Thoroughly clean everything (BB shell, cups, etc.)
2) Wrap teflon tape around the BB cups (making sure that it's in the
direction that won't "unwind" when you screw in the cups).
3) Slather the inside of the frame's BB shell with grease
4) Slather the inside of the BB cups (in the case of a cartridge BB)
with grease, and put some on the outside of the cartridge where
they'll be inserted into the cups (this interface is one of the
biggest potential "noise generators" on a bike)
5) Slather some grease on top of the teflon tape
6) Install, torquing to spec (pretty darn tight if you don't have a
This will keep your BB quiet and happy for a long, long time."
I used teflon tape (lots of it, like 3-4 layers) on the BB. Worked fine for 20 miles or so and then started clicking. I tightened it pretty tight (didn't use a torque wrench). I could have tightened it a tad more but was worried about stripping the BB or the cups (more likely the cups).
Any new thinking on the advice of Mark Hickey above? I didn't use any grease when I installed the cups, just teflon tape. Any other ideas? I assume if I use all my effort I can strip the BB cups, and obviously don't want to do that.
