it. I mistakenly did one wrong on my own bike and it was painfully
obvious in the stand that it just didn't fly, so I flipped it, and
life was good.


There is another problem with them, but it is mostly on the Shimano
ones.. They seem to have a propensity to break.. a run of chains
with weakened/weak side plates got made, and the link pins pull
through. Not cool. Warranty them out though.


This is a far more serious matter than cost. It's safety. When a
chain beaks in a standing sprint the rider generally flies over the
bars. This is why you shouldn't sprint in top gear on SA-AW
three-speed hubs. They reliably pop into neutral under load and speed
due to a basic design problem for which they should be taken to court
for damages.

wow, and to think that all those years i had one growing up, and all
those times i'd sprint to the end of the road against my friends, i
never ever had it pop out of gear. not even once. was mine the
defective one if this was otherwise a "reliable" occurance?

Nahh, just means you pedal like a girl.

What happens if fitted with the heart "upside down"? I checked my
two bikes with Connex links and I see one is right side up and the
other upside down. I never noticed any difference in how they rode
or shifted.

Supposedly it doesn't work so well on very small cogs.

Don't do that! What do you mean by "supposedly" and how is that
caused. This is not religion class. We can't rely on the
infallibility of the Pope here. "Let's get to the facks ma'am, just
the facks", as Sgt. Friday would say.

OK, I'll be more specific. On my bike they make a clicking noise in
the 12. What this means in performance I don't know -- I blindly
followed the printed instructions not to use it that way after
noticing that problem. Oopps, I don't mean problem since I have no
proof it was a problem. Call it a phenomenom observed by me.

Those instructions seemed to correspond in some way to my experience,
but my experience didn't prove anything. Oops, I shouldn't have said
"seemed" -- please strike that from the recond. Since I don't have an
engineering degree and have not run double-blind tests, I'll try to
refrain from putting in any heresay in this group (though Brandt did
ask if the manafacturer gave any info on this, so I guess heresay is
acceptable in those circumstances.)

But I will refrain. Heresay is not aceptable obviously. Thank you for
keeping us so clear.

Please accept my sincere apologies.

Now was that so hard?

eg

Now kiss his spoke wrench and be gone...

B and might I add S

The Connex link MUST be installed the right way around. Looking at
the drive side of the bike (from the right), when the snap link is
on the top horizontal length of chain, the cutout should look heart
shaped..i.e, the cut out starts at the top, lowers towards the
centre, and then rises again to the top.

YOU MUST FIT IT THE RIGHT WAY AROUND

Could you explain what effect the orientation of the master link has?
If the link can be installed in the wrong orientation, it will be
incorrect as often as not. Can you cite an admonition to that effect
in the Wipperman installation instructions?

I have a hard time with absolute statements to which I can find no
logical supporting evidence. They sound like religious dogma.

The shop where I bought my bike (in the UK) is owned by an ex sales-rep
for a major bike manufacturer. He told me that this manufacturer
supplied bikes with Connexe chains and it wasn't until numerous bikes
were returned with chain 'problems' that they were informed by the
manufacturer of the correct orientation for fitting.

OK, this might be boll*cks. BUT, the Wipperman instruction leaflet
clearly shows how to fit the link, and if it wasn't important they
would just show a length of chain rather than the complete 'loop'.

I just follow manufacturers instructions. On my 4th chain, I ride 8'000
miles per year...never had a problem.

Not from that 'store' site no. But if you care to look at the
manufacturers site at:

Click on 'tests' and then item '02'..you will see it in, well not black
and white, but 2-tone grey (sorry gray).

Still having a hard time?

Wow. I was trying to figure out what all this meant, wondering if
"heresay" was about "an opinion or a doctrine at variance with established
religious beliefs" or merely "an out of court statement offered to prove the
truth of the matter asserted," and then I began to wonder if it was an
intentional conflation of the two. Then my head started to hurt. So...
nevermind.

Why you posted this as a reply to me and not JFT is a mystery, as is you
questioning the use of a word YOU added to the thread.

Otherwise, nice post 8-)

Dear MSA,

What a wretchedly clumsy site! You can't link directly to
anything, or even copy the text!

Here's the relevant passage:

"Fixing the chain via the ConneX Link is straight forward
and simple. However, do take note of the orientation of the
link. The plates are asymmetrical and the user has to ensure
that the more rounded side should brush against the cogset
(Refer to the diagram, you can see the top side is more
rounded than the bottom one). If the wrong side is used, it
will cause shifting problems and the chain to skip."

In what language is this "sentence"?

(FYI, it's called a "follow-up"; a "reply" is a different thing
altogether.)

Otherwise, nice post 8-)

That's hair-a-see!

ObRBTContent:

Now that the gd bar exam is done, I've actually started riding some
again. (But Jesus, it's a hundred out every day in 95818. Who knew?)
So after peeling off some cobwebs and doing some inspection, I see most
of the tires on the three bikes need replacing. With the bike and me over
200lbs. (91kg) in each instance (disgusting, but waddayagonnado?), I'm
thinking I should be honest and get rubbers that are durable, rather than do
the wannabe thing and buy way-too-thin, over-priced "racing tires" in an
attempt to live out a fantasy. Nashbar has a pretty broad selection. Gimme a
recommendation for the next few months where I make the transition from the
90 min./day ride up to 300 mi/week (all good road). Thanks, Rico.

Even more. I see no explanation of the link's orientation under that URL.

Dear Jobst,

You have to go to the indicated section and then scroll
down:

"Fixing the chain via the ConneX Link is straight forward
and simple. However, do take note of the orientation of the
link. The plates are asymmetrical and the user has to ensure
that the more rounded side should brush against the cogset
