Crank arm power meter review

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.

With or without a power meter: don't forget to enjoy your ride!

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

Quick start guide installing and using the power meter

Data from the power meter, compared with speed, cadence and heart rate data

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

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