    Help with missing link chain... i messed up...

    First time changing chain....

    I bought a KMC 9.93 chain and tried to replace my chains: http://www.amazon.com/KMC-X9-93-Bicy.../dp/B001AYJF2E

    I messed up and took out the darker part of the chain and left the whiter part to be connected, and it won't go in..
    What can i do? I tried to reattach the darker parts without success.

    Use 2 quick links and make chain correct length, or buy a new chain.
    Triples are for the weak and the old.........I guess that make's me both
    If you wait until you're ready, you will wait forever.

    You misunderstood my question.
    The chain link is suppose to go in with the darker part of the link not the silver part.
    I made a mistake of getting rid of the darker link at the end of my chain. The chain length is correct but now that i want to connect using the missing link it won't go it.
    Should i get a new chain or somehow connect the darker link i took out?

    Just take off the outer (lighter) link, connect your chain and carefully check that you have enough chain for largest chainring/ largest cog.

    You misunderstood my answer, you may need to splice in a link after remove the "silver" part.

    I'm sure the mechanic at the LBS can reattach the link you removed if you can't. If he has a replacement pin, they usually have a starter section on them that allows them to be inserted easily. Time to visit the LBS.

    Buy something like that. It's always useful to have quick links.

    Starter pins look like this: Amazon.com : Shimano HG Chain Pin (9-Speed, 6.5mm, 5-Pack) : Bike Chains : Sports & Outdoors.

    They have a narrower end so you can insert it through your link.

    One more thing you can do without resorting to the LBS: Assuming you still have the excess links (maybe between 3 and 5), take off another full link from the chain BUT BE SURE TO LEAVE THE PIN STILL ATTACHED TO THE OUTSIDE PLATE. You do this by pushing the pin almost all the way out, then flexing the plates by bending the chain sideways. That will free the link(s) you plan to remove but still leave the pin stuck into the outer plate on the other side. Then put the extra links back in and push the pin all the way back in. Now you have a chain that is one link shorter than when you started. Start over to make the chain the right length, but be careful to leave inner sections on both sides so you can use the master link. Only problem with this is you aren't supposed to reuse pins on narrow chains, but I doubt it will cause you a problem.

    The pin stuck in the chain should look like this:

    Do not reuse KMC pins that have been pushed out. As part of the manufacturing process, the heads of the KMC pins is flared or mushroomed, and the act of breaking the pin loose from the chain sideframe breaks a ring of metal off the pin, This makes the pin unsuitable for reuse.

    The correct way to fix the problem that you have created is to get some additional KMC "Missing Links" (they cost about $1 including shipping from multiple eBay Sellers with delivery taking about one week). Knock off the outer link/s (the silver ones), so your chain is restored to having inner (dark colored links on both ends).

    Is the chain too short now? If the chain chain length is acceptable, use a "Missing Link" to join the ends after you install the chain on your bike.

    If the chain is too, short, then you need to lengthen it. When you got the chain, it should have been too long, and you should have had to shorten it to the right length for for your bike. The cut-off piece that you rejoin needs to have an inside link (dark link) on both ends to use a Missing Link to rejoin it to the chain and lengthen the chain. Now you should be back at SQUARE ONE, with the chain too long and off the bike.

    I recommend using a "shop size" chain tool to break the chain (I bought a Park Tool Chain Tool 3.2), because I found that the mini chain breakers that I used to use don't have the strength to break modern chains meant for index shifting systems (modern chains have flared or mushroomed heads on the pins). I also bought the Park Tools tool designed for removing and replacing removeable links like the KMC "Missing Link". The tool is not necessary for installing the links, but it makes removing them much easier.

    Resize the chain for your bike, shortening the length by removing links. The chain should work on both Big-Big and Small-Small when you are done sizing. Make sure that you leave inner links on both ends of the chains, so you can use a Missing Link to join the end with the chain on the bike AFTER you size it.

    That's fair. I have never had trouble with reusing a pin from a narrow chain, but Road Guy's suggestion is better.
