Concept2 Damper Settings Explained: Why 10 Is Not Automatically Better
Understand the difference between damper position, drag factor and stroke rate before you turn the lever up.

You sit down on a Concept2, see a lever numbered from 1 to 10, and assume the top setting must deliver the best workout. It is an understandable interpretation—and an unhelpful way to choose your setup.
The better question is what the setting changes, and which numbers tell you about the work you are doing. This guide focuses specifically on the Concept2 RowErg. Do not transfer its settings directly to a magnetic or water rower with a different resistance system.
What the damper actually changes
The lever controls airflow into the flywheel housing. More airflow makes the wheel slow faster between strokes, changing how it feels to accelerate it again. A lower setting allows it to retain more speed between strokes. [1]
Think of the lever as a way to change the feel of the stroke, rather than a numbered achievement ladder. On this air-resistance system, pulling harder spins the flywheel faster and creates more resistance; the lever alone does not determine workout intensity. [1]
Three numbers that answer different questions
| Number | What it tells you | What it does not tell you |
|---|---|---|
| Damper position, 1–10 | Where the airflow lever is set | How hard you are working |
| Drag factor | The flywheel slowdown measured by the monitor | Your fitness level |
| Stroke rate, strokes per minute | How frequently you complete strokes | How much power each stroke produces |
The monitor uses drag factor in calculating work. Two machines can produce different drag factors at the same lever number, because conditions and the cleanliness of the flywheel housing affect airflow. Matching a lever position is therefore not the same as matching drag factor. [1]
Where should you start?
Concept2 recommends starting the RowErg's damper between 3 and 5, then adjusting according to the session and what works for you. This is a starting range, not a universal optimum or a progression target. [2]
On the monitor, select More Options → Display Drag Factor to view the measurement while rowing. Record it alongside the lever setting if you want a more useful reference for another session or another Concept2. [2]
For a simple setup comparison, keep the session format consistent and note the setting, drag factor, pace and perceived effort. Change the lever only while stopped or resting. The aim is to find a repeatable setup, not to prove that a higher number is more impressive.
Moving faster is not the same as producing more power
Stroke rate can rise because you rush back and forth, without a corresponding improvement in output. Concept2's guidance distinguishes cadence from how effectively you accelerate the flywheel. Look at your pace or watts alongside stroke rate, rather than treating more strokes per minute as automatic progress. [3]
Imagine two entries in a training log: one session records more strokes per minute, but no improvement in pace. That entry calls for a closer look at how the session felt and how the stroke was performed; it does not justify a confident claim of improvement from cadence alone.
Keep comparisons honest. An easy session and a hard interval session have different purposes. A setting that feels appropriate in a short effort need not be the one you prefer for a longer row.
Useful habits—and misleading shortcuts
- Useful: record the setup and repeat a familiar session when comparing changes.
- Useful: consult the manufacturer's technique guidance when the stroke feels awkward.
- Misleading: copy someone else's damper number without considering their machine or session.
- Misleading: judge progress entirely by lever position or stroke rate.
The benefit of a consistent setup is a clearer training log. Its limitation is that no single number describes technique, comfort and effort together. Use the monitor to inform your judgement, not to replace it.
Frequently asked questions
Is setting 10 wrong?
No. It changes the stroke's loading characteristics and can have a purpose. It simply does not guarantee a better workout, faster result or more appropriate setup. [2]
Can setting 4 still be demanding?
Yes. Your effort contributes to the resistance you feel on an air rower. A modest damper number is not the same as a low-effort session. [3]
Should everyone use the same drag factor?
No single value suits every person and session. Begin with the manufacturer's guidance and refine the setup around your needs, with coaching where useful. [2]
GymVerity's recommendation
Give each number a job: use the damper to choose the stroke feel, drag factor to help reproduce that setup, and performance data to understand the session. Keep a brief note of what felt controlled and repeatable. Turning the lever up is a setup change, not a training milestone.
