How to Calibrate a Protege Bicycle Computer

A properly calibrated Protege series bicyle computer helps you keep track of your ride statistics.

Protege is a line of bicycle computers from Planet Bike, including the 5.0, 7.0 and 9.0, which have five, seven, and nine functions respectively. According to Planet Bike, all Protege series bicycle computers feature current speed, riding time, trip distance, cumulative odometer, 12/24-hour clock and auto start/stop/LCD shutoff. Higher models have additional functions. The calibration procedure for the set of standard features is the same for each computer in the series.
