    Two Wipperman Connex Links Broke!

    Rode fine with these for 3 years (Ultegra and DA chains), then in the last 2 months, two of them broke. Both times I was going uphill, the last time it was when I shifted under torque, though the first time I was not shifting.

    Few questions:
    1. If this pretty common?
    2. Bought a couple KMC Missing Links to try out. Anyone have comparisons between the Missing Link and the Connex?
    3. I also bought a couple KMC 10 speed chains (Nashbar had them on sale) that I plan to use soon. Have not found anything telling me whether I can reuse the pins on those or how I can shorten/connect the chain other than by using a Missing Link. Can I use the Shimano 10 speed pins on the KMC chain?
    Thanks

    I have not had a problem with mine but now you got me worried. I am assuming you had them installed correctly and not upside down right?

    I don't trust master links that snap together. And I don't recommend using Shimano pins with any other brand of chain. Specs always vary a little.

    Please describe how they "broke".

    I don't think I'd use a detachable link for more than three chain lives, probably two is more realistic.
    I had one come apart once, and it was definitely installed correctly. I was fortunate to find both pieces on the road. After that, I started to carry an extra just in case. Remember, the repair link is subject to the same forces as the other links and will wear.

    I'm running a KMC on one bike and it's working fine as is the link.

    Why would you want to reuse the pins? that's what the link is for.

    Using Shimano pins in another brand chain just doesn't sound like the thing to do, does it?

    Sram links are supposed to be only used once, but I've removed and replaced the same ones a couple of times. They do take some time to remove however.

    What do you mean by upside down? How can I tell if my ConneX is installed correctly or upside down (on an SRAM 9sp if it matters)?

    Yes, learned that lesson long ago with the annoying click on the 11T cog.

    Well, any other ideas for chain pins? They don't seem to sell separately like Shimano does for their 10 speed chains.

    Both times the pin separated from the plate. Just broke off and left me with a single plate and no pin.

    I would want to reuse them if the chain broke on the road and I didn't have a spare Missing Link (like what happened to me yesterday with the Ultegra chain and the Connex link--ended up reusing the Shimano pin since I had no choice).
    I agree using Shimano pins sounds odd, but they look pretty darn similar and KMC doesn't seem to sell theirs separately. Perhaps they want you to use 2 or more Missing Links if their chain breaks other than at the Missing Link. Could be, as they are not too expensive anyway. Just hoping the Missing Links do better in the reliability department.

    Look at the curve of the link. Match the curve of the link to the curve of the chain. The sides are different. I hope that made sense.

    Got it. Thanks. When the link is at the lower segment of the chain, the curved slot should form an "A" shape and not an "U" shape.

    http://www.connexchain.com/data-live...onnex_Link.pdf

    I would think that if the orientation is that important, the instructions should be more clear about.

    Anyway, I will verify tomorrow that my link is installed correctly. I am 50% sure that it is ;-)

    One thing to look for. The older Wipperman links are labeled 10S1 and are not suitable for use on Shimano 10spd chains. They are the right outer width, but there is not enough inside clearance, hence they do not flex under load like the normal links. I would think plate separation would be a likely consequence. Check and see if you had one of those on there.

    The new Connex links say "10 Speed" on them and can be used with any chain.

    What do you mean by "older"? I bought these links a year or so ago (installed the last one a month or so ago) and I think they were the 10S1 (don't have the box), which supposedly were especially made for Shimano chains. Are you saying they were wrong? Wiperman's website is completely devoid of useful info on this subject. The sense you get is they want you to buy their chains and not their links.

    Also, Performance still sells the 10S1.

    I have used Superlink, and SRAM links for years, with no failures.

    A year a go I built a new bike with Campy, and used a Wippermann chain.
    300 miles later the link disconnected while downshifting up a hill, with one half getting lost in the weeds.
    That was the end of my use of Wippermann.

    Funny you mention that. I read somewhere that Superlink beats them all. Wonder if I should give those a try.... Perhaps after I go through my two KMC Missing Links.

    I started using Superlinks in the 90's, and was happy until at some point they seemed to have changed the material they were using, and the darn things started wearing out *fast*. I mean like in as few as 200 miles. You could feel it in the pedal as the link came around the cassette cog. Close examination would show the inner sides of the pins were wearing away.

    At that point I switched to SRAM links, which proved *far* more long-lasting. The SRAM posts have a spiral groove around the pins which I assume is to help move oil.

    Now it has been some years ago that I switched to SRAM links, and meanwhile the Superlink mfgr has changed from Craig to Forester, and now I think it is somehow owned by Lickton. I am currently running a SRAM chain on my Campy road bike, but have a new Campy chain and Superlink 4 waiting for the next time it needs a new chain.

    They are "older" but still all over the place and on closeouts frequently. The 10S1 is fine on the Wipperman chain or Campy chain, but not Shimano 7801+. It may have worked on the original 7800, but then they redesigned the chain. It is also a problem that a lot of online sellers are confusing them. For example, this link calls it a 10S1, but the photo shows the right link that says "10 Speed" on it.

    http://www.bikesomewhere.com/bikesom...501/4853/31183

    If you measure with dial calipers, the 10S1 is narrower ON THE INSIDE, not the outside. This sometimes makes the chain bind through the pulleys or break on hard shifts.

    I threw out all my old links so I don't have the exact measurements anymore. I just avoid problems and don't use links that are stamped 10S1 unless I am using them on a Wipperman chain that they came with.

    I actually got a bunch of links on sale at Performance a few months ago that they were calling 10S1, but that were all stamped 10 Speed.

    The DA CN-7801 and Ultegra CN-6600 chains are the same in dimensions. The original DA CN-7800 was different and quickly replaced by Shimano. They warn against using the wrong connecting pins between them, so I think there was a dimension change in the width.

    No one sells the 10S1 anymore, and I wish they did because I need some. They just have not updated their pictures. Any site that you order from will send you a "10 speed" link. If you get a 10S1 link I will personally purchase it from you (seriously!).
