    Replacement Chain - Length

    Hi everyone -

    As time goes on I am making sure to do all my maintenance myself. I have what may seem like a rather stupid question.

    I bought an Ultegra 9 Speed chain, and am going to replace my current chain.

    How do I know if it is the right length? (I am on a Specialized Allez Comp 58cm)

    My brain tells me there must be different lengths, since my wife rides a 47cm Trek, they could not possibly need to be the same length!

    Thanks in advance.

    Matt

    Your question isn't stupid, but here's my stupid question... why not just make it the same number of links as the old chain (since the old chain will be stretched)? I don't actually count links, just lay 'em down side by side and match links.

    I do that, and it works fine. The old chain will be just slightly longer than the old, but just slightly.

    You're right on the money. That's the procedure to use. Don't measure the old chain, but instead you count the number of links. Using your chain tool you then "cut" the new chain to the correct number of links.

    Of course this is assuming that the chain was the correct length to begin with. I use the big chainring to the big sprocket method described on parktools.com
