# How Do You Calculate Gear Teeth

### Gears, Velocity Ratios and Mechanical Advantage

Gear Ratio • You can think of gear ratio as a multiplier on speedand a divider on torque. • You can calculate the gear ratio by using the number of teeth of the “driving gear" (a.k.a. the inputgear) divided by the number of teeth of the “driven gear” (a.k.a. the outputgear). More Information

### Gear Ratios: Gear Reduction vs Overdrive

Gear Ratio. Gear ratio refers to the number of teeth or one gear's diameter in relation to the other gear in a set. The gearset in the top illustration indicates gear reduction. The drive gear turns twice for every one revolution of the driven gear. Its gear ratio is 2:1 and increases torque. More Information

### How to Calculate the Capacity of a Rear Derailleur - ApexBikes

You can do this by deducting the number of teeth between the largest and smallest chainring. Let us say that the largest is 44 and the smallest is 22, then we get 22. Secondly, you must calculate the maximum cassette cog difference. This can be done by deducting the number of teeth between the largest and smallest cassette cog. More Information

### Sheldon Brown's Bicycle Gear Calculator

If you're using a Schlumpf Drive plus an internal-gear rear hub you should enter the actual number of teeth of the front chainring for the first chainring, and this number of teeth times the Schlumpf ratio for the second chainring. The ratios are 0.40 for the Mountain Drive, 1.65 for the Speed Drive, and 2.50 for the High Speed Drive. More Information
