R600 compact cranks on a Cannondale CAAD9. Started to hear a 'creaking'
under loading of the left crank arm, maybe after the first 100km.
Raised the issue with the guys at LBS - who suspected it was something
else doing the creaking - pulled the post, stem, forks out and greased
and re-fitted. Still creaking, so pulled the cranks out, re-greased and
re-fitted - silent again.
LBS suspects the rear wheel, but I know that aint where the sound comes
from. I take the wheel back to the wheelsmith for a chat. He
demonstrates to me that it isn't the wheel.
After the next 100-ish-km, creaking returns. I ask them to upgrade the
BB, although they assure me it's not the BB. They pull it down and
replace the BB - silent again.
After the next 100-ish-km, creaking returns. LBS fingers the blame at
the left crank arm, and returns to Shimano for warranty exchange. Fit
new arm, silent again.
After the next 100-ish-km, creaking returns. I haven't bothered to
take it back to the shop for another session, and I get the impression
that they're tired of chasing the creak. Still, it's pissing me off as
I wasn't expecting something like this from a brand new bike - and from
such calabre as a Cannondale.
Anybody got any thoughts on this one??

I own two Cannondales - 2000 CADD4 and 2004 Optimo. Both have given me
the same creaking problem from the BB. I have used Shimano Ultegra
6500 and DA 7700 and FSA bottom brackets. To rid the noise I have
faced the BB shell, then apply a thin coat of grease (Teflon)* or
equal to the cup threads and torque to spec. Added note: check
chainring bolts. Hope this helps.

I sat and watched as the LBS wrench did all of these things - seem
this is a bit of a Cannondale feature, and they've been selling them fo
years. Nice to know they're on the right track. I called them today t
organise a time to get some Teflon tape on the threads, and they're kee
to give it a shot

Stop fixing it and locate the creak.

Oh. You only want advice that agrees with

My wife would probably ask if plumbers teflon tape would hold up in the
rain. ...just like she asked one day whether it would be a good idea for me
to get the plumbing pipes I just bought out of the bed of my truck in case
it rained over night.

Square taper cranks seem to work dependably and quietly for most riders.

Apparently, even for those who repack their BB every time they ride in
the rain. A press fit would not seem the method of choice for something
that is frequently disassembled, however.

Left hand cup of a sealed BB can creak if not tightened properly. So can
old/work/loose pedals. Another common cause is the saddle rail bolt.

Fair call, but the BB cups have been removed and re-fitted 3 times - s
i'll give the LBS wrench the benifit of the doubt that he's got it righ
at least once. Pedals have been checked. Saddle is silent - especiall
when I climb out of it.
Something is working loose somehow, as it's silent for a while afte
the cranks have been removed/re-fitted, but then it start's creakin
again under load

cannondale bb threads are cut a little large in my opinion. this makes
creaking real hard to prevent because the bb is never really snug. i'd
try a layer of teflon plumbers tape and see what happens - it'll fill
the threads a little.
