Mystery part... Part of Campagnolo chain or installation?



A

Artoi

Guest
Just replaced the chain with a new Campag Ultra Narrow 5.9mm Veloce
grade chain last night and took it for a ride this morning. After the
ride, while wiping the bike down, I found this tiny polished metallic
ring on the Rt chain stay. It must have held on by static electricity or
a bit of sticky grease.

The tiny metallic ring measures approx 4mm diameter and is made of
polished metal wire of approx 0.35mm in diameter.

Anyone know where it might be from? Could it be part of the chain that
was just installed?

One other thing I noticed is that this chain is a lot quieter, near
silent, compared with the KMC chain that came with the bike. I noted
previously that with the old KMC chain, the Chorus cassette ran pretty
much silent while the Veloce cassette (both new,12-25, 2006 model) was
noisy despite adjustments. Even though with a bit of run-in, the Veloce
cassette got to be a bit quieter, but it was still not the same as the
Chorus. Now with the new Campag Veloce chain, it's equal with that
Chorus. Interesting bit of anecdote.

No. You worry to much...

Dear Lou,

Wouldn't you begin to worry if you found bits of metal stuck to your
chainstays by static electricity after a ride?

Maybe, but I still can't explain where that component came from. It's
too delicate and clean to have come from the road. And when I saw it, it
was resting perfectly at the top of the chainstay towards the very rear.

It's just really bizarre!

I guess no one has seen or heard of any parts like it. Oh well...

You do get a little circlip around the end of the spindle that the QR
lever is on. Not the spindle through the axle, but the eccentric shaft
thing that the lever itself rotates on as you open and close it.

The shaft sticks out the other end from the handle and may be retained
with a circlip at that point. I don't think the one on my bike is a
complete ring like you describe, but perhaps it's from there? You could
check it's not missing. I lost one once and made a replacement by
cutting a small shape from the wall of a plastic coke bottle.

Sounds like a roller from one of the chain pins, just got stuck there
after you shortened the chain(?).

If everthing is working properly and after checking the bike, no. This
piece of metal could easily be picked up by the tire.

Dear Lou,

Maybe this will clarify things . . .

Static electricity?

Ah, I get it now ;-) Yes that's something to worry about.

Did you clean the KMC chain with solvent?

How did you lubricate the KMC chain?

Absolutely, it's regularly cleaned and wiped. I use Weldite's spray-on
lube every week.

The key issue here is that there's a difference in noise level b/n the
two cassettes. RD adjustments just doesn't make a difference, even
through LBS.

Well, I wondered if it's a part of the chain, but it's definitely a wire
rather than a roller that has a significant width. But looking around
the chain, I couldn't see anything similar. Is it a component of a chain
design?

It's not a circlip and the found ring certainly has no strength for a
circlip.

I was considering the possibility that the KMC chain was under lubricated.

Yes, that was one consideration. But the cassettes were used on the same
bike/chain. So it made no sense to work perfectly with Chorus but not
Veloce.

In any case, the problem has resolved with the new Campag 5.9mm Veloce
chain. So I guess there is a difference somewhere. As for the KMC chain,
it was one that came with the bike, definitely not their top of the line
10 speed product with that X patterned external plate.

Cheap chains are noisy. KMC has a reputation for making cheaper,
noisier chains. You have discovered why they have this reputation.

I drive diesel these days, they are pretty safe in that regard. :p
