Gear Ratio Calculator 2: Precision Engineering for Your Perfect Drivetrain

Gear Ratio Calculator 2 is a bicycle application that calculates gear ratios and simulates performance for road and MTB bikes with external gearboxes. It generates speed-cadence and gear ratio graphs for component selection.

Gear Ratio Calculator 2 supports 22 different chainwheel, 39 different sprocket, and 70 different tire combinations. New data for these components are added as needed.

The Gear Ratio Calculator 2 app provides five types of graphs: km/h RPM, mph RPM, m/s RPM, Gear Ratio, and Gain Ratio. These visualize speed, cadence, and distance per crank revolution.

Gear Ratio Calculator 2 allows users to turn on and off the display for each gear (outer, center, inner) to simulate and visualize the optimum gear ratio. This helps in selecting replacement parts.

Yes, users can add custom bicycle parts in Gear Ratio Calculator 2. The app provides an interface for entering new part information, including cranksets, sprockets, and tires.

The Gain Ratio graph in Gear Ratio Calculator 2 calculates and displays the distance traveled per crank revolution for each position of the selected chainwheel and sprocket.

The app's Gear Ratio graph calculates and displays gear ratios for each position. It indicates that greater distances between points signify increased load on legs when shifting, while closer points mean less load.

Gear Ratio Calculator 2 offers speed-cadence RPM graphs in three units: kilometers per hour (km/h), miles per hour (mph), and meters per second (m/s).
