    i was changing the rear derailleur on my racer and when i went to open the chain to run tru the derailleur i put the chain tool onto the chain but pushed the pin all the way out by mistake.

    is there a way or getting this back in or do i need a new chain?

    any comments greatly appreciated..

    It can be put back in with the chain tool, just is a pain in the ass to do...

    It's a pain in the ass to do. Just pop that link off and use the next one. Your chain will be a little shorter than it should be, but you should be fine. Just remember when you're replacing the the chain that you need the new to be two links longer.

    You could also get an SRAM powerlink or a shimano chain pin to replace the missing one.

    Take the chain off the bike and lay it on a bench/table.
    Put the two ends of the chain together.
    Hold the pin with a "Pointy Nose Pliars".
    "Gently" tap the pin in with a hammer about 1/3 of the way.
    now "gently" pull/twist the chain apart and refit onto the bike.
    Use a chain breaker to push the pin back in.

    I've done this on many occasions...not a problem.

    Its not best practice and is not recommended by chain manufacturers to reuse a pin once it has been pushed out. You can easily buy a new pin as Seamus says.
    It would always be on my mind that it could go any time, not worth the risk.
    For future reference - if your just changing the deraileur you can take out the two jockey wheels and leave the chain in place. Do the reverse when fitting the new deraileur.

    lads could i ask how often is it recommended to clean your chain and how do you do it im new to this game as you can tell:D

  • Registered Users Posts: 68,317 ✭✭✭✭seamus

    As often as it needs it. :D

    Depends on how much riding you do and what kind of weather you're riding in. If you're riding every day in fine conditions like we've had for most of March, you'd get away with using a light chain lube once every two weeks. You wouldn't need to clean it for about 500km.

    In wet weather you'd want to wipe it down and re-lube it every 200km, at least.

    I'd say you can reuse pins safely up to 7 speed (I have with no issues.) 9 and 10 speed, certainly not. 8 speed I am not sure, I don't have anything 8 speed.
