O-ring colours

The colours of the o-rings are important and have changed over time.

The RED and the GREEN o-rings are for Gen 1 power meters ONLY.

The BLUE and the YELLOW are for Gen 2 power meters ONLY.

They are NOT interchangeable.  Misuse of the incorrect o-ring can lead to many issues that are NOT covered by warranty!
