What Drag Factor Really Measures
The machine calculates how quickly the flywheel slows down between strokes.
A high drag factor = the flywheel slows down more = it feels heavier, like rowing a big boat.
A low drag factor = flywheel slows down less = it feels lighter, like a fast racing shell.
Damper setting (1–10) controls how much air enters the cage.
Drag factor is the actual measured effect of that airflow.
Two machines on damper 5 can have different drag factors if one is dusty, older, or at elevation.
That’s why athletes use drag factor (a precise number), not damper level (imprecise).
90–115: Lightweight rowers, beginners, athletes with back issues
160–200+: Extremely heavy—generally not recommended
Low drag (lighter feel):
High drag (heavier feel):
1. On the Performance Monitor: More Options → Display Drag Factor
4. Adjust damper until you get the desired number
If you’re doing VO2 max work or HRV-aligned endurance rowing, your ideal drag factor is usually:
Smooth, efficient, minimizes back fatigue during long sets.
