Chain Length Calculator

The Time Length Calculator is designed to help you easily calculate either the time length or the final distance based on your inputs. For the Basic Calculator, simply enter the total time (in seconds) and the total speed (in meters per second) to get the time length.

For the Advanced Calculator, input the initial velocity (in meters per second), acceleration (in meters per second squared), and time (in seconds) to determine the final distance. Choose the calculator according you needs, fill your values in the required fields, and get accurate results instantly.

Length Of Chain Calculator

























What Is Chain Length

For cyclist the chain length is very important for smooth operation of bike diver train. It is about the total length of the chain required to connect the front chain ring to the rear cog. So, It is very important to ensure the proper chain length for efficient power transfer, smooth shifting and to prevent chain slipping.

It can be challenging for you to calculate the chain length of you bike manually due to various factors like chain stay length, the number of teeth on the chain ring, and the cog.

Chain Length Calculator Formula

For accurate calculation of the chain length, This calculator works in two different modes basic and advance. Following I have breakdown the formula’s for each mode. The basic formula considers the chain stay length and the number of teeth on the front and rear gears. The advanced formula includes an additional adjustment factor for chain slack.

1. Basic Chain Length Formula:

Chain Length=2×Chain Stay+(Front Teeth4+Rear Teeth4+1)

2. Advanced Chain Length Formula:

Adjusted Chain Length=2×Chain Stay+Total Teeth4+Adjustment

How to calculate chain length?

Following are the steps to calculate the chain length using the basic and advanced formulas:

1. Basic Calculation:

  1. Measure the chain stay length in inches.
  2. Count the number of teeth on the front chainring.
  3. Count the number of teeth on the rear cog.
  4. Apply the values to the formula:
    Chain Length=2×Chain Stay+(Front Teeth4+Rear Teeth4+1)

     

2. Advanced Calculation:

  1. Measure the chain stay length in inches.
  2. Sum the total number of teeth from the front chainring and rear cog.
  3. Determine the chain slack adjustment in inches.
  4. Apply the values to the formula:
    Adjusted Chain Length=2×Chain Stay+Total Teeth4+Adjustment

     

Calculation Example

1. Basic Calculation Example:

Calculate the chain length if the chain stay length is 15 inches, the front chainring has 40 teeth, and the rear cog has 20 teeth.

Solution:

Using the basic formula:

Chain Length=2×15+(404+204+1)
Chain Length=30+(10+5+1)
Chain Length=30+16
Chain Length=46inches
