    Reusing pins when reconnecting/assembling 11-speed chains

    I'm not talking about totally removing - as in totally out of the chain - the pin. I'm talking about pushing a pin 80% through, separating the link, then reattaching the chain by pushing that pin back home. I've been doing this forever - going back to the BMX days and thought the 7, 8, 9, 10, 11 speed evolutions.

    Rumor has it, that method of pushing that pin back to reattach the chain stopped being okay with the 10-speed chains. Something about the flair on the pin, the pin being shorter, etc.

    Was there a significant change in the design from 9 to 10-speed that changed this? Or, is it that it was always less than perfect and it reached a tipping point at the 9-10 change?

    I would never ever do this.

    Never.

    Ever.

    What on earth could make it worthwhile?

    I'm thinking he's got a good dental plan now, and is interested in trying it out.

    I should add that I've moved on - I stopped removing/reattaching chains that way. Just wondering when it became such a bad idea... well, that assumes it was ever a good idea.

    I'm thinking like you...right around the time we went to 9 speed. It always seemed to be fine w/ bmx bikes and old 6, 7, and even 8 speed chains where there was a decent amount of pin proud of the plate. That ended w/ either 9 or 10 speed, can't remember exactly when but I seem to remember the Shimano guys saying don't do this anymore.

    Yup, nope - not on an 11 speed chain.

    New pin or a quick link.

    I've experienced a chain failure (Wipperman link) and lived to tell about it. It was the second worse experience I've ever had on a bike (#1 is being hit by a car!).

    I remember it being a bad idea once Shimano went to the snap off pins last century, which I promptly ignored and after repeatedly pulling chains apart, switched to Sachs and never went back.

    I too use Wipperman chains on some bikes.
    I have not had the connex link fail while riding but have found one with a crack in it and changed it for a new one. It was an 8-speed model. Big crack from pin to edge.

    I noticed it when reconnecting after routine chain maintenance.

    I always look at them carefully now and have yet to see another one cracked.

    Going on about 10 or more years now using them on several bikes.

    Guess sometimes this kind of stuff happens. Glad you were not hurt.

    Considering how cheap chain pins are, there's no reason to take the risk. Heck, there's no reason to take the risk anyway.

    And from what I understand, you should never break a chain in the same place twice. Is this true?

    Actually, that method stopped when 8 speed chains started.

    Yes, true. If you are using the Shimano pin you should go to another spot on the chain to break it.

    What's the preferred method - the Wippermann/Powerlink/Quicklink or the break-away pin?

    A quicklink is less much less hassle and lasts just as long. There's really no reason not to use one, and save yourself some time/effort.

    I prefer to use some type of link, especially if the chain is on a bike that gets overlubed or really dirty. It's just a bit easier to take the chain off for cleaning. Doesn't really matter, but that's my preference.

    Yup, it was 9sp. That's when the side plates got too thin and they started making the pins flush. So you couldn't safely push the pins out and back in.

    8sp had longer pins so there was some margin for error.

    When I break my 11sp chain, a tiny 'ring' pops off the pin and is left on the punch of my chain tool. It's the flare that was on the side of the pin seated on the punch. I've broken my chain twice, and there are two rings on my chain tool. I noticed them last night; what a coincidence now I see this thread. Anyway, that's enough for me not to try to reuse them.

    Exactly my understanding, thanks!

    Now for the big question. Is it ever acceptable to re-use a quick link?

    With Campy, it was 10s. But the issue is the same regardless of brand: they started peening the ends of the pins to hold them in place and so reusing a pin wouldn't work.

    There are some that are designated as reusable.

    Personally, I reuse them (even the non-reusable ones). I've had zero issues.

    Spending $10 or so to replace something free is a reason. I'm not that cheap but I'll gladly spend the extra 1 min. for $10.

    Although someone in another thread was saying Shimano now includes quick links with new chains, so maybe now there would be no reason.

    Shimano pins aren't free. Topic at hand is re-using pins. If you want to split and re-connect your chain, it's $3.33 a pop.

    3 for $10.

    6 for $14 ($1 cheaper than Shimano pins)
