|The easiest way, assuming your original chain is the correct length, is to simply match the length of your original chain.

|The Park website left out the best method of adjusting the chain length.
To adjust the chain to the correct length, shift to the little ring and smallest cog. Wrap the chain around the little ring, the smallest cog and through the derailleur, with the ends coming together below the right chainstay. Remove two links (one inch) at a time until the lower derailleur pulley moves a small amount when the ends of the chain are brought together (indicating that tension is being applied). Install the connector link and rotate the crank. The chain may rub against itself as it passes under the upper derailleur pulley. If it does, two more links (another inch) of chain should be removed to increase the tension and create some clearance between the upper and lower section of the chain. When this is done, the chain has been set to its maximum useable length.
Tha advantage to this method over the large cog/large chainring method is that it assures the chain will be long enough to handle any cassette within the derailleur's stated cpapacity. If you use the large cog/large chainring method with a 23T max cog and later change to a 27, the chain would be 1 inch too short.

|the length for most road bikes is 106 links. Best place to start is with your old chain, and then try the big-big or small-small combo procedures. Unless you have a very wide range cassette or unusual chain ring combinations, I'd need to know why 106 wouldn't work.|| |
