I have always used shimano chain in my drivetrain, but I had some questions about the chain instalation regarding the use of the special connection pin and the plates of the chain...
I know that every time you cut the chain you have to put it together with the special pin, but I was installing a new chain and put two pins trought the same hole. I mean, the first pin with it`s guide went perfect to connect the chain but the pin breaks in a weird form I can`t describe, well I said, "no problem, I have other pin here", with the new pin everything went in perfect. My only concern is, if the plates of that link of the chain get bigger (because the first pin went trough it and the second fits fine, making the special pin not a "tight" fit)??
Or you can use the same link every time you want just, being carefully not to reuse the special connection pin???
It shouldn't be a problem. If you were to part a chain (remove a pin) for some maintenance reason you would have to put the replacement pin in the plates where you parted the chain, so that makes two pins through the same hole, as you put it, no different than what you did with the new chain. If you need to part the chain again, part it at a different link.
Don't part the chain unless absolutely necessary!!
[font=Comic Sans MS]I swop my chains at 1000km,when changing back to the first chain the link was damaged from the chain breaker,i then USED A SRAM,missing link on my shimano 9 spd chain but it clicks a little on changes,so i used the extra links that came with the new chain and cut and linked using 2 shimano pins.and it runs fine so don't loose those couple of links you cut off the new chain.[/font]
Visit your local bike shop, buy a Connex link, it's only a few dollars...very cheap. Remove one pin out and fit the Connex link as per the instruction sheet, it is extremely easy. Any time you need to remove the chain for cleaning, etc, you just pop out the Connex link, it is so easy...and reinstalling is easy as well. Makes much more sense than buying 3 or 4 pins and struggling with the chain breaker each time 😄 😎
