Hello

When setting up the Garmin Edge 820 with Arion Digital Smart B+, in the settings I am asked for a few things that I am not sure about.

Circumference - I know I can leave this field blank as have seen in the FAQ section
Bike weight - is this needed?
Gear ratio - is this needed?

Thank you

Hi

If you connect the trainer as a fe-c trainer, circumference and ratio are not needed.
About weight, it may be needed for calories calculation I suppose, but you should ask Garmin directly

Regards

Thank you

I will leave these blank.
