The only thing you will have to do is ensure that the powermeter is "zero'd" before every ride. Which is simple, place the righthand crank so that its at the 6o'clock position and press the button on the control unit until the LED light turns blue. When it's blue, release the button and the LED will begin blinking, the zero offset calibration is then complete. The reason for zero'ing the powermeter is so that it knows what a zero load is, meaning that the ride you are about to embark on is as accurate as can be.
