Broken chain advice

Hi all,

The other day my new chain broke and one of the links got all bent up. Should i run the chain 2 links short or would i be better off adding a couple of links meaning i'd have 3 starter pins in the chain (are starter pins weaker than others?)

And before you all say, just buy a new chain, i'm in Vietnam where 9-speed chains just aren't available. Cheers.

Damo

Don't change the number of pins on a chain - that's not a random number (usually!) so better keep it. But the necessary links you can add from another chain. Even an old but not too worn out chain will do - it's only a link you need, no?

If you only need one link you might want to try using one of these:

I have used Quik-links for years with no problems on a variety of chains. Just find the right one for your brand and size of chain.

That costs US $4. An old chain costs nothing.


Just sayin'.....

You mention "starter pins" so I will assume you mean any pin that you put in the linkage, whihc was not already there.
First, I do not believe starter pins are any more trouble, or softer than other pins. So for saving money, add the links. Could you run one link shorter, most likely. It will just lessen your ability to run cross cogs a bit. As for "master links" like Shram puts out, they work great and would only leave you 1/2 link short.

Last summer, I took off my chain to clean it toroughly and lube it. Then I put it back on the bike, but didn't close the pin correctly. So, a few tens of kms later, the chain broke off! Back home, I just got rid of the broken link, checked the chain length and put it back on the bike. It's been a few thousand kms since then and the bike with its 'repaired' chain is still going strong!

Make sure though that the chain is long enough by trying it on the big chainwheel and rear big cog. Better check it before braking cogs or chainwheel with a too short chain...

From reading this I assume you are going to use Shimano pins which are just as costly but if that is what you have handy, go for it. Personally I detest the Shimano chain system. If the pin is not set "just right" disaster of some sort ensues.

No, I would just use a link from an old chain - any old chain as long as it's the same width and it's not _too_ worn out. Because it's only one link, it will have very little impact on the cassette and chainring, during the chain's lifetime.

The shimano pins, as far as I can tell, are just something you can use if you have pushed a pin all the way out - making it almost impossible to put back. Then you would use a shimano pin. Otherwise, just any link will do. By the way, shimano pins are about 1 EUR/piece here in Finland, and Finland being the most expenisve country in the world, I am guessing that they are about as cheap or cheaper in the US, so, still cheap compared to $4. But as I said, you can use a link from an old chain.

Maybe people overthink these things, or feel that if there is a solution that is very cheap (in this case, free), that it's not good. I don't know which one is the reason, but I have done this many times. Not because my chain broke - that never happened, luckily - but because I needed it longer by a link to accomodate a larger chainring or sprocket and didn't have enough room to maneuver in the (track or horizontal) dropout.

Said all this, I am not disputing the validity of the above advices. It's just that I experienced mine as working well, and is cheap, so I am mentioning it. Maybe someone will try it and be satisfied.

You have the right idea-just run it 2 short.The derailleur will work just fine on all but the BIG-BIG combo you never have to use anyway(or big second to biggest combo).Heck, it will shift better a bit shorter in some combos.
Just shift around any problems,and run 2 short.
Luck,
Charlie
PS-Adding two links will work of course,Do you have a decent chain tool.Remember to just barely "loosen" the tight link( use the in more inboard part of the chain tool) once you install them.The pin tips should"stick out" fairly evenly on both sides.
