Compatibility check for other crank arms

Before you order a product from 4iiii, check whether your crank arms are supported by 4iiii. We'll show you how to check this. You will need the following items: printer, ruler, A4 paper, scissors, tape and a AAA battery.

1. Print the following image on A4 paper. The lines should go to the edge of the paper.

2.Use a ruler to make sure the size of the center is actually 10 cm and cut along the lines.
3.Place the crank arm on your bike so that it is horizontal to the rear. Many 4iiii are designed specifically for the left crank arm, so we recommend using this for compatibility check.
4.Turn the paper strip over so the pedal side is on the right side and tape off.

5. Now hold a AAA battery vertically between the crank arm and the wheel frame. If you can move the battery freely in the gray area of the strip between the crank arm and frame, the Precision Powermeter will fit your crank.
