Drag factor is a measure of fan load. The Performance Monitor self-calibrates by recalculating the drag factor on every stroke, so you get a true measure of your effort regardless of the damper setting or changing conditions. You can adjust the drag factor by moving the damper lever on the right side of the flywheel. (Learn more about damper setting and drag factor)

- Begin rowing or skiing. The PM will display the drag factor after a few seconds.
A brand new indoor rower will have a drag factor of about 90–100 at a damper setting of 1 and about 210–220 at a damper setting of 10.
