PB Blaster is not an anti seize compound. It is a solvent designed to
break down bonds between pieces that have already seized. (Works great
btw). Anti-seize compounds are used between metals that tend to react
with each other to prevent them from bonding together, such as titanium
and aluminum. Creaks are caused by loose fitting parts. Either something
that doesn't fit properly, like an out-of-round or poorly faced bottom
bracket, or something is loose and dry, like the bottom bracket cups,
crank spindle, seat rails, pedals, quick releases, chainring bolts
(common), un-lubed seatpost, etc, etc, etc.
Anti sieze won't do much for you in this case. Check other stuff and
substitute parts to help rule out different systems. Regularly
disassemble and re-lube fasteners and clamping surfaces.
Best of luck. Chasing creaks can be a real pain, but if it's creakin'
something ain't right...on the bike anyway.

try the derailleur hanger (may be loose) or the cassette fixing nut. have thought my BB was the culprit but actually was one of the afore mentioned.

B Mills

2009-09-18

Thank you all for the GREAT suggestions, looks like I may have my work cut
out for me to check several things. I am going to assume it is NOT the BB
at this time and go through a few other areas first, including but not
limited to, (and in No particular order):

- Headset
- Seat Post/Seat Rails
- Skewers
- Hubs
- Cable Rub
- Pedals
- etc, etc, etc

BTW - when I mentioned Anti Seize, I was thinking of the stuff recmmended by
Park

Thanks again for all your suggestions, I will find the creak !!!!

Cheers

In fact, antisieze is what Park recommends in their blue book of bicycle
mechanics for applying to crank/spindle interface. There is no way correctly
applied antisieze on this interface can make it into the bearings.

I don't know how the PB Blaster came up, but that stuff is NOT anti-seize.  It's essentially WD-40 with some detergents to help break loose rusted/frozen in place fittings.

Anti seize is a paste or cream in a tube or jar that is applied ONLY to the threads of threaded components, especially WRT bike components, ti to ti (ti to any metal really), alu to alu, or stainless steel to stainless steel (and some other steels).

Anti seize is used because it doesn't dissipate or spread thin in warmer/hot conditions like lighter lubes (i.e. slick honey) due to some additives (one of my tubes of anti seize has copper in it).

Another thought popped into my head.
 
Is this a Dura Ace 7700  B/B?
 
The 7700 is well know as being one of Shimano poorer designs. It is well noted that they tend to get noisy over time.

I've found that the brake and shifter cable ends resting tightly (in the down/top tube or seat stay tubes) in their stays stays can also create the illusion of creaking as the bike is ridden.

body{font-family: Geneva,Arial,Helvetica,sans-serif;font-size:9pt;background-color: #ffffff;color: black;}p{margin:0px}PB Blaster is not an anti-sieze, but rather a penetrant agent for loosening corroded or seized threads or metal/metal contact (that were not likely applied in the first place with a true anti-seize compound).  When properly applied, an anti-seize compound will have no effect on the bearings or their lubricants.

Ditto on that. I’ve found lightly greasing the rear hub bearing caps and tightening the rear skewer typically eliminates noise.

As Strader stated, stay away from antiseize stuff…some mechanics use plumbing tape on the threads if nothing else works…

I bet it's not the BB at all. Have you tried running a different BB/Crankset pair? Just throw an old square taper deal in there for testing.

The last time I was 99% sure I had a creaking BB, it turned out to be a mildly loose rear skewer.

I installed a new outborad bearing BB (Shimano DA) a few months ago and it has started creaking in the last couple of weeks. I also have newer Ultegra Cranks. I took it all apart , cleaned all threads very thoroughly (on the BB and the Shell) and reassembled, per their instructions and I liberally greased the threads. I also checked the frame for any cracks or other imperfections, but the Creaking continues. I've done several tests and am 99% sure it is the BB creaking. This is on my commuter bike which has an aluminum frame.

So now I'm thinking of trying some Antiseize compound, but not sure if this will fix the problem, so a couple of questions..

- where do I find Antiseize compound ? What brand is Good to use ?

- any sthoughts as to what else may be causing the Creaking ?

Thanks

Another thought popped into my head.
 
Is this a Dura Ace 7700  B/B?
 
The 7700 is well know as being one of Shimano poorer designs. It is well noted that they tend to get noisy over time.

Not sure where the anti-sieze came into the picture, but that idea may not be so good. Anti-sieze products such as PB Blaster will leach into bearings and destroy the grease surrounding the bearings. Be careful with this stuff.
 
Did you follow the tourque specs and make all adjustments with a torque wrench?

I've found that the brake and shifter cable ends resting tightly (in the down/top tube or seat stay tubes) in their stays stays can also create the illusion of creaking as the bike is ridden.

In the past, when I've had creaks in my BB, the creaking has been audible in
the dismounted bearings. If they're off the bike and you can hear grinding
when you spin the pieces, it's probably the BB. If the bearings turn freely
and quietly, it's probably one of the many other excellent suggestions in
this thread...

This may very well be something else. The alumn frames can resonate
creaking to sound like it's somewhere it isn't.

Try the anti-seize, but it could be a number of other things. Even if
it's only when you pedal, you shift your weight and move lots of things.

Here's what has caused creaking on my alumn bikes:
Seatpost too long (rubs in st on tubes that get wider)
Quick-releases (ESP the cheap qr Allen locks, they creak like crazy)
Ovalized HT
Saddle rails

Don't forget to lube your seatpost, I have seen saddle rails and the post/frame interfaces make noise.

Anti seize is generally purchased at auto parts stores, and the brand I usually get is permatex.  I have both silver and copper.  Be careful not to get it on anything besides the parts you want lubed, it is kind of a bugger to clean up.

Cheers, Mike.
