You pull the handle on your Concept2 RowErg and the chain clatters, slips, or the flywheel barely responds. This is one of the most common calls we get on Concept2 rowers in Dallas Fort Worth, and it almost always comes down to the chain, the sprocket, or the internal clutch mechanism, not the flywheel itself.
Common Symptoms
- Chain rattles or clatters during the stroke instead of moving smoothly through the housing.
- Handle pulls loose with little resistance even at a high damper setting, as if the flywheel has disconnected.
- Chain visibly sags or hangs loose when the handle is at rest in the housing.
- Grinding or clicking sound from the flywheel housing as the chain pulls through.
- Chain jumps or skips on the sprocket mid stroke, causing a sudden jerk in the handle.
- Monitor shows inconsistent or zero pace readings even though the flywheel is spinning.
Root Causes: What Is Actually Happening
- Dry or dirty chain. The chain runs through a felt pad lubricated with a specific machine oil. Once that oil dries out or the chain accumulates dust and grit from a garage or uncarpeted floor, the chain no longer moves smoothly over the sprocket, causing rattling and inconsistent engagement. This is the single most common cause and the cheapest to fix.
- Worn or damaged sprocket teeth. The small sprocket inside the flywheel housing that the chain rides on can wear down over years of use, especially without regular lubrication. Worn teeth cause the chain to skip or jump under load.
- One way clutch bearing failure. The clutch mechanism inside the flywheel allows the flywheel to spin freely on the recovery and engage on the drive. When this bearing wears out, the handle feels like it has no resistance because the flywheel is not actually connecting to the pull.
- Chain misalignment from the fan cage or housing. If the chain has come off track slightly inside the housing, it can catch or rattle against the fan cage rather than running cleanly over the sprocket.
What NOT to Do
- Do not use WD-40 or a general purpose lubricant on the chain. Concept2 specifies a particular type of oil for the chain and felt pad. The wrong lubricant attracts more dust and can gum up the mechanism faster than running it dry.
- Do not keep rowing on a skipping chain. A chain that jumps the sprocket under load accelerates wear on both the chain and the sprocket teeth, turning a simple lubrication fix into a parts replacement.
- Do not open the flywheel housing without knowing what you are looking at. The one way clutch and sprocket assembly go back together in a specific orientation, and getting it wrong can make the problem worse or introduce a new one.

Frequently Asked Questions
How often should I oil my Concept2 chain?
Concept2 recommends oiling the chain roughly every three months for light use, more often for heavy or daily use. A dry, dusty chain is the most common cause of the rattling and skipping symptoms owners report.
Can I fix a skipping chain myself?
If the cause is simply a dry or dirty chain, cleaning and re-oiling it with the correct lubricant is a straightforward owner fix. If the chain still skips after that, the sprocket or clutch bearing is likely worn and needs a technician to inspect.
Is a rattling chain a safety issue?
It is not an immediate safety hazard, but a chain that is skipping under load can snap back unexpectedly. It is worth addressing before it worsens rather than continuing to row through it.
