Length of the chain stay.
Bicycle chain length calculator app.
3 is green 2 3 blue and below 2 red.
For example some derailleur bike chain could only be 51 52 53 inches etc.
You can save your configurations.
Tests have been performed to control stones.
Centimeters inches and millimeters.
Besides it allows to calculate in different units.
Chain length calculator does nothing more and nothing less than working out what the length of your chain should be expressed in number of links.
When using newer gear wheels with 11 teeth the chain length needs to be extended by 2 links 2 55 cm.
Csl chainstay length in inches f front gear cog teeth r front gear cog teeth.
For this step it really important to not run the chain through the rear derailleur.
This video will take you step by step through sizing a bike chain including determining whe.
I have no idea how the magic number of 0 0796 was derived but the formula appears to provide a pretty good approximation to the shortest possible length of 1 2 inch pitch bicycle chain that will theoretically go around the two cogs on a fixed wheel bike.

Colors group similar values.
The result applies to gear wheels with 10 teeth.
Chains cannot be cut to 52 1 4 53 1 8 or even 52 1 2.
Now add one whole inner and outer link so that you have approximately one extra inch of slack in the chain.
