Subject: Bottom Bracket Noise

...have a 12+ year old ti frame with ultegra crank and bottom bracket that
were the originals from when I assembled the bike. ...haven't ridden the
bike in a number of years, but just recently got back on. I'm noticing a
clicking that seems to be coming from the crank or BB. ...doesn't appear
when coasting and seems to grow a bit louder when pushing harder. ...also
seems to click once per revolution. ...bike might have perhaps 10-20,000
miles on it over the years - probably closer to 10, since I think I was
largely riding my tandem during that time instead. ...but it definitely
wasn't there a few years ago when I was riding regularly. ...am about to put
together a new bike, but am planning to keep the old one for commuting or as
a back-up.

...so what's the chance that the click can be solved by simply disasseming
the crank and bb and giving everything a coat of grease? Is it even worth it
to expect the BB to last as long as it did? I looked quickly on-line and it
looks like everything went to the external cups and/or the splined drive
things rather than the traditional square axles that I'm used to while my
bike was collecting dust in the garage. I really don't want to replace the
perfectly fine crank, especially since I'll primarily be riding the new
build, and I don't really want to pull everything apart just to find out
that I need a new BB (or should just replace one that old) if I don't have
the replacement already available.

Thoughts and recommendations?

I had a similar clicking "noise" which I thought was emanating from the
crank. It was always more noticeable when I was pedaling and never when
coasting. As it turned out, I traced it to my newly purchased Fizik Arione
saddle. I squirted WD-40 on the rail connections and where the metal seat
pieces inserted into the plastic assembly (front/rear). Next ride --
SILENT. Now if I could only get rid of the occasional chain noise
(low/high gears), it would be incredibly peaceful. Some guys blow by me on
bikes that make almost NO sound -- stealth! I wonder how they do it...

Finally reached 50 years of age and I'm sufficiently affluent to have the quality well-maintained bikes I always
wanted. But now my knees make more noise than the drive-train on the road-bike, and when I am climbing hard the gasping
for breath sounds drown out any mechanical noises from my MTB!

I'm 45 and my orthopedic surgeon suggests daily doses of Glucosamine
and Chondroiten. It has the same effect as an anti-inflammatory drug
such as Dolobid or even Advil, however, it takes 6-8 weeks to reach
its full effect.

Why take these supplements ?? In one clinical trial, after 2 years,
the people taking Glucosamine and Chonrdoiten showed no degeneration (
no decrease is cartilege width ) in X-rays taken at the end of the
study, vs. width at the beginning of the study. Thus, these
supplements effectively halted osteo-arthritis (the wear-out arthritis
that everyone gets). The people taking anti-inflammatory drugs had
significant narrowing / loss of cartilege in their joints after 2
years of drug usage.

That's too funny! I'm 56, a relative newcomer to cycling, and also
appreciate being able to afford nice equipment -- however late it is to
really take advantage of it. While not too much is grinding in my old bony
frame (so far), my lung capacity and endurance are no match for most women,
some children, many recumbents, and even a few tandems. Sheesh! I get
passed by just about everyone, including handicapped guys pedaling trikes
with their fingers. At least if I could have a quiet bike, that would be
something of pride...and would disturb fewer passersby as they scorch past
me.

The click could come from many places.
Your effort is best spent determining
exactly the source of the click. One
rider here tracked down a bottom bracket
click to his shoe lace ticking on the
crank. It could be the saddle or seat
post or pedal. Or something even
further from the bottom bracket.

GOOD chance..also look at pedal/cleat for noise, the source of most
type noises.

Is it even worth it
> to expect the BB to last as long as it did?

Square atper or Octalink spline, In either case, it is a cart bearing
and the only difference is you can tap the right cup off on the square
taper, UN-72 type BB, to add grease in there as well.

Goitta get yer hands dirty to evaluate this problem..or have a decent
LBS do it, they chould have replacement parts. DON'T need a new
crank.

Initial diagnosis can be done with clean hands.
* Ride one footed
* Ride no hands.
* Ride out of the saddle.
* Try every combination of riding styles.
* Heck, take you shirt off.
* It could be you sunglasses clicking on your helmet.

I seem to have recently fixed one by "cracking" one of my triple
chainring bolts tighter.

Do the same thing to the pedals and the seat post/saddle. I had a
'creaky BB' that turned out to be a slightly under-torqued seat post.

Square taper cartridge BB's are still easily available:

It's likely that a thorough disassembly, cleaning, and reassembly will
either find the problem or simply make it go away. If you grease all
the threaded parts (including chainring bolts and pedal threads), I'll
bet yor mystery noise will go away.

Thanks. I'll give it a try. ...already did that with the quill type stem and
that solved the problem there.
