any downside to Wippermann Connex link?

Bob Ross

I'm thinking of getting a Wippermann Connex (or equivalent quick-
disconnect link) to make cleaning my chain & drivetrain easier. Is
there any downside to these gizmos?

I've read 1 or 2 anecdotes about quick-disconnect links coming undone
at the starting line of a race (!) but as far as I can determine
that's not a common enough occurence for me to worry about. I'm more
concerned with whether they affect longevity/durability of the chain
or cogs, or if they affect shifting, or... well, anything that might
be viewed as a negative.

Any reason I shouldn't consider one?

I swore off the Wipperman ones after one broke as I was taking off
from a 4-way stop last year. I was barely moving, but I went down
pretty hard. Since then, I've stuck with KMC and SRAM quick links,
more out of superstition than any empirical quality concerns.

Like you say, it's not a common occurrence, but once is really all it
takes.

Seconded. There are 6 cyclists in this family, and I use
various width SRAM Powerlinks (black, silver or gold, depending
on the chain width) without any problems whatsoever.

I've used Wipperman conneX links only twice, and a side plate
failed on one of those, breaking the chain.

I have a Wipperman link but it's on a new, as yet unfitted chain. My
SRAM quick-disconnect links have so far lasted 3200km on one bike and
2200km on another bike, in each case on the original chain. The chains
are in full crankcases, so there is no dirt to set up a grinding
action. I use White Lightning dry wax lube, so it is easy to see in
the bottom of the crankcase where the little balls of wax collect what
it is that they surround -- and on these bikes is mostly oil that
didn't all quite get cleaned off the the chain before I applied the
wax, not dirt. I gave both those bikes their six-monthly service a
while ago and inspected the SRAM links somewhat cursorily without
disassembling the chains; they were obviously fine, not thinned out
anywhere. For perspective, my open chains last about a thousand miles
and a bit, say not quite up to 2000km, and the SRAM quick links on
those have always seen the chain out.

After the comments here perhaps I won't even try the Wipperman quick-
link, and instead use the proven SRAM quick-link on the Wipperman
chain. Or it may be that it is a chain hygiene matter, that a properly
clean and lubricated Connex link will last as well as the SRAM one.
How well did you fellows with the Connex breakages look after your
chains?

I'm definitely a convert to the benefits of fully enclosed crankcases.

HTH.

Does that have a derailer inside?

Wipperman Connex links are fine. Never had any problems with them and
I'm using them for almost 10 years on my road bikes. They are easier to
open then the SRAM links and are better made IMO. Only downside? They
are more expensive when you buy them separately.

No. These are singlespeed/8speed chains. The gearboxes are Shimano's
Nexus 8 speed hub gears, zero deraileurs, just a control cable,
mechanical in one case, electronic in the other. There are a lot of
pics of one of the electronically controlled bikes here:

and a pic of the mechanically controlled bike here:

Enjoy!

I wish now I'd taken a photo of the little balls of wax inside the
crankcase at the end of six months of winter riding, which show either
that White Lightning dry wax is bleeding marvellous or that we should
immediately petition the President to make full chain cases compulsory
for all bikes (to save rising water, high quality oil and energy).

In my case, the bike was only 2 months old, and had 300-400 miles on
it. I didn't have fenders on it at the time, so I'm pretty sure it had
never been ridden in the rain (I had my fendered touring bike for rain
days). I was in a 34-17 gear, starting from a dead stop, IIRC.

I've just thrown away a Connex link as the pin wasn't riveted square
with the outer plate. If used I can imagine it would have been the weak
link. Other than that my experiences with them are fine. They don't open
as easily as SRAM links when flopping about in a carboot (only of a
concern if you clean your chain ). Look for the shifting chamfer on
the linkplates to install them the right way up

My experience with the SRAM goldlinks lately are that I have to fiddle
with them for 15 minutes before installing to remove the sharp edges of
the slots, which makes opening a big PIA.

Not in my opinion. We have sold hundreds with no problems whatsoever.
We use the 6mm one on just about every 10s chain we sell(Campagnolo
and shimano),

I'm guessing the SRAM link can cause excessive wear on the two
adjacent links.

I've used the SRAM links on my 9-speed chains for 7 - 8 years now.
Never had one break.

I check for "chain stretch" with one of those Park tools when a chain
starts to approach 3,500 miles of use and typically reach the .75 wear
point just shy of 4,000 miles but *only* if I span the tool across the
SRAM link. Every other part of the chain measures as being under this
wear limit. I sometimes get a few hundred more miles out the the
chain by replacing the old SRAM link with a new one, which brings the
chain back into spec across the SRAM link, but it pretty quickly goes
back to the .75 wear limit.

Since this out of spec condition exhibits itself only when the tool
spans the SRAM link it seems like the adjacent links have accelerated
wear.

Nobody has mentioned that the Connex is asymmetrical, while all of the
other links are symmetrical. The difference: the Connex will skip on
an 11 tooth cog if installed "upside down." For an impatient dyslexic
like myself, that's enough for me not to bother with it when the
others don't have this defect, are at least equally good and better if
the failure anecdotes in this thread are true, and cheaper. I use IRD
snaplink for 10 speed.

Not a racer, myself...but I have commuted over 5000 miles without a
problem using a Connex links using wipperman and Record chains
