Fitting your own chain on your bike, as daunting as it may seem, is very simple – with the right tools.

First things first, take your old chain off.  If you don’t know how to do that, fear not.  I’ve got your back.  Click here.

Second, clean the drivetrain; chain rings, cassette and the jockey wheels on the rear derailleur.

Do not skimp on that step!  Why get a bunch of old crap stuck in your brand new chain?!

Next, on five or six attached sheets of paper towel, lay the old and new chain next to each other.

Now it gets a little tricky.  See, I know how much a chain stretches over time, so laying the two next to each other, I know which link I want.  My wife, being my wife, didn’t trust that so she counted the links…

Now you know my wife was right.  She took all that time!  So was I.  Right on the money.

For the next step, I took over.  Take a chain breaker and break the chain at the proper link.  The following is how the chain goes into the breaker:

Then you just crank it down till the pin falls on the ground (I use a small crescent wrench for leverage 😉).

From there, all you have to do is put the new chain on.  Bob is officially your uncle.

As a side note, because my wife made this mistake, be sure to thread the chain through the jockey wheels properly:  Don’t loop over the metal tabs, the chain goes “under” them.  Give the pedals a good spin.  If you’ve looped over a tab, you’ll know by how hard it is to turn the pedals.  Incidentally, this is what it should look like:

See that little tab, darn near exactly in the center of the photo?  Originally my wife threaded the chain over that tab.  That’s bad.  Just so you know.

    Well done Mrs Jim! Great instructions and even I might be tempted to try this.

      The only trick Sheree is getting the right chain break… The small ones take more torque than I can put on them so I have to use the wrench shown in one of the photos. 😉

      Oh, and that was her first go at it too!

    I like the fact that you just said your wife was wrong but you still seem to be alive and blogging… what’s the secret? 😉
