    Bonking ... not feelin' well chain breaking question......

    broke my 8 speed Shimano chain twice today, powering up steep hills! This has never happened before. The chain was starting to get stretched, and I have a new chainring, but the chain hasn't been skipping. The chain has been taken apart many times in the past 3 years ( I'm not a high volume rider) as I experiment with SS setups. Does seperating a Shimano chain, and then reassembling it significantly weaken the chain at that link, even if it is only once?

    Depends on how you sepparate it and re-join it. Shimano uses pins that are shaped at the ends so that pushing the pin through the side plate with your chain breaker actually enlarges the hole in the side plate, this is why shimano chains require the special black pins for re-joining. If you've been re-using the pin then you've been extremely lucky so far.

    For Shimano chains I like using the "Missing Link" connectors. Personally on the SS I don't see the need to spend any more than a PC-7 costs. It's a good chain, compatible with 1/8" components and it's got those pimpin gold sideplates.

    your supposed to replace pins

    with some new ones that they sell for like eleven dollars or something.

    Use a sram pc 58 or 68 or even 48 its a lot stronger than shimano(I think everyone will agree) and you get a powerlink that you can remove without tools.
    I've been inside too long.
