How good is a power meter?

Installing and using the 4iiii Precision Powermeter

Aug. 28, 2019 - Willem L. Middelkoop

After I created a minimal road bike, I decided to install a power meter to find out what's it like to measure the power output of my legs. What can you learn from a power meter? Is it difficult to install? Is it worth it? Read along to find out.

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)

You should be able to loosen the plastic cap with just your fingers/hand, no extreme torque is required

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

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