# Use a Bicycle Gear Inch Calculator to Determine Various Ratios The bicycle gear ratio is used to determine the maximum speed which it is possible to ride a bicycle at while also determining the smallest circumference that the bicycle can accommodate while also determining the ratio of the drive and the wheeling force. These two numbers, the ratio of the drive and the wheeling force, are derived by dividing the total force on the bicycle by the force required to propel the bicycle forward. There are six numbers that are used in this calculation; they are the ratio of the drive to the Wheeling force and the ratio of the Wheeling force to the total force. This information can be found on the specifications label of each individual gear in any type of bicycle and is usually located on the rear derailleur hanger.

Bicyclists often use a bicycle gear inch calculator to estimate the right size for them when purchasing a new bike or for repairing an old one. The calculation of the gear ratio is often used to determine the maximum speed that a bicycle will reach during an exercise. It is also commonly used to test the performance of bicycle gears in relation to each other. The size chart of a bicycle is used by most bike shops before a customer purchases a bike.

## An Overview There are many different ways in which a bicycle gear inch calculator can be used. The easiest way is to find the size that fits the user comfortably. The size of a bicycle gear is often specified in millimeters. This measurement is taken from the top tube of the bicycle frame to the handlebars. For the purpose of this article the top tube of the bicycle frame is assumed to be the frame directly above the saddle.

A bicycle gear inch calculator can also be used to determine the correct amount of derailleur gears to add for any given speed. The calculation is done by taking the ratio ‘gain ratio’ and dividing it by the current speed. In order to find the right gear ratio that can be used on a particular bicycle the calculator can be inputted with the following information: speed, gear teeth, crank arm length, seat tube length and the type of bicycle.

## Bicycle Gear Inch Calculator This calculator can also be used to find out how many tooth cogs your bicycle has. The calculator uses the same measurement that was used above. However it requires that the front wheel hub is changed to the appropriate diameter to match the spindle on the rear wheel. The calculator then deducts the spindle from the wheel’s diameter to get the number of tooth cogs. This is called the tooth quotient.

There is another relative measure that is used in a bicycle gearing system. It is called the ratio of toothlet to crankcase. This is a ratio that tells the width of the tooth on the crank to the length of the crank axle. This ratio is figured by adding the crank length to the inner edge of the tooth on the crank. Using the calculator, you can find out if your bicycle gearing is working properly or not.

In order to determine this ratio, you must divide the total tooth length by the crank length, or just divide the tooth count by the crank length. Use the bicycle gear calculator to find out the ratio of toothlet / crankcase. There are other calculations also that can be done using the calculator. It is also possible to find out if your bicycle has adequate gearing.

## Bottom Line

A way to find out whether your bicycle has high or low gearing is to compare different setups with the same crank lengths. You can compare different setups by changing the ratio of toothlet / crank case by changing the length between gears. The reason why this is important is because some derailleurs and sprocket sets will have more teeth on one side than on the other. Therefore, you may think that the bicycle has low gearing when in fact it may have very high gearing. To compare different setups, you can start with the smallest group and go from there. By looking at the end result, you will know what type of gearing your bike has.
