Just put a 7sp z chain on my commuter, with the missing link. I'm curious why the missing link is needed? The chain looks normal to me, but the instructions say it could break if the original pins are reinserted. What benefits are there to construct a chain this way?
Also it says the missing link can only be removed with a chain tool, but I thought you could unlink these things by squeezing the rollers together with pliers? If I use a chain tool to remove it, will it be ok to reuse a few times or does one need to buy a new missing link each time?
