    Shimano chain connector pin

    I accidentally split my new HG93 chain at the wrong link.
    I pushed the pin back in as I only had one connector pin.
    Is it ok to use the chain having split and pushed back one of the pins?
    Or should I get a new connector pin and replace the pin I pushed out?

    I do use a proper Parks chain tool for the splitting so there should be no 'damage'.

    no worries.. I have done it several times with no issues... in theory you should use a connector pin...but I have pushed the pin back several times without worries...

    The ends of the pins are "mushroomed" or "peened" to keep them in place. When you push the pins out it breaks this portion of the pin off. This is why you need the special replacement pins. The probable (but not guaranteed) outcome for pushing used pins back in is that a plate will pry itself off the pin and the the chain will break.

    If you know where the pin is you should take it out and replace it. If not, you'll have to wait for it to fail. In the meantime, you may wish to buy a couple SRAM powerlinks that makes taking chains on and off a lot simpler and less expensive.

    BTW, having a chain break under you is not a pleasant experience as it happens when you are putting maximum load on the pedals climbing uphill.
