This is a gear, speed and shift point calculator. Given a few bits of information on your drivetrain and tires it will computer shift points, max RPM. You can enter tire size by the standard profile numbers or by the tire diameter. Transmission gear selection can be from a list of some common gearboxes or enter the gear ratios (Up to 8 Speeds) manually. What's this for? Well you can use it to size your tires, rear axle ratio and determine shift points and all that. This is an EZ to use and web based shift point calculator!
The calculator outputs speed in each gear at 5mph intervals up to the maximum RPM. This is a text file for easy printing, just cut and paste into your word processor or text editor. It also computes charts for Gear Ratio Slope, RPM Gear Drop and a Shift Point Chart. Use this data to optimize your driving.
These charts are interactive, you can zoom, and click on various parts of the chart to read data at the mouse. If you are on a phone your mileage may vary.
