At first glance, this may not seem applicable to anyone but a mechanic… but think again. I discovered this app to be very useful when choosing chainrings for my XX1 drivetrain. For any rider with a 1x setup and the ability to swap chainrings for different rides, it is a fun utility to calculate time and distance based on different gear ratios and cadence. This app calculates the distance you will travel and the number of pedal rotations using your gear ratios, and you can also calculate the distance and the time it takes at a particular cadence with different ratios. Aside from being something fun to tinker with, you may find how much faster you cover your favorite trails with different gears… both up and down.
