Installing and using the 4iiii Precision Powermeter

Aug. 28, 2019 - Willem L. Middelkoop

Wahoo RFLKT+ showing realtime data from my bike computer app - obviously I was standing still here... all the zero's (except my heart rate)

Use a crank tool to remove the crank (Shimano TL-FC16 / FC-M960)

Make sure the battery is installed and the covering door is locked

The crank arm has it's model and length written on it, on my bike that's: FC-5800, 172.5MM
