The amount of fud and ridiculously unsafe practices makes my head explode. It's simple, don't ****ing reuse a completley pushed out pin on ANY chain. It's not worth the labour or the risk period. Even if it was only partially pushed out, you'd still be risking chain failure on 7+ speed chains (let's assume you're smart enough not to do this on IG/HG shimano chains).

A sram masterlink retails for $4. Allows infinite amounts of reconnections/disconnections. You can't **** it up. Once it's engaged on the chain, it's engaged, there's no fuzzy logic invovled in whether or not the chain is competently reassembled. It's a mystery why on earth, shimano has taken this long to come up with a masterlink type connector for their chains as it is.

DO NOT REASSEMBLE THAT CHAIN wihtout a masterlink!.
