A couple of concerns I have with this regarding their method of attaching their handle to the C2 chain swivel. They are using a steel (probably stainless steel) fastener that interfaces with the stainless steel swivel body. With any movement between these two parts there will be resulting wear. But ...

I'd guess that the axle and/or flywheel have shifted outward towards the cage, which is not unusual and often also results in slow handle return. There may be a retaining clip missing somewhere- it's going to take some investigating. Can the flywheel be slid side-to-side at all? If you remove the fl...

Two key bits of information: does the monitor work and how much are they asking? Have you had a chance to try it out? If the flywheel isn't hitting the inside of the cage then the dent is probably not an issue. The occasional slipping could be the clutch or a skipping chain, both of which could be f...

Personal preference has a lot to do with it. It's important to have a plan and try it out as much as possible before the event. If you plan to eat and drink during the marathon, then you need to practice doing so on the fly to minimize down time. Have a couple seating options like a towel or bubble ...

The noise is gone. Thank you again!

Great and you're welcome. I think the culprit was a tolerance stack up in the thickness of the laminations and the space available between the cover and base housing pieces. Easier than changing bearings!

Will this be true for both "jet engine spooling down" sound on spindown AND for rattle sound during the drive ? We have one erg doing the first, and one doing the second. Will definitely try this. TY. It's worth a try. Sometimes the Generator Cover screws get stripped, resulting in the generator ra...

Might be better with a small dab of silicone under the tach pickup. Its not going to stick to the plastic that well if you ever need to pull it out but it will definitely take out the movement and the resonance. The tape is just to act as a shim, not an adhesive. The generator needs to be held tigh...

Funny thing- Mine has had that noise for a few years now and your post inspired me to look into it. It's never been a concern for me because I'd heard it before and it's most often got to do with the generator unit vibrating inside the generator housing. So first thing to try is tightening the two P...

Info on blade path and development

the donut piece was originally welded to the flat plate. If you know someone with a welder or if there is a machine shop near you they should be able to re-weld it. Note that the orientation and position is critical! You'll need to clean the paint off to get a good weld. It's possible that it could ...

You should send an inquiry directly to Concept2. They have staff who are experienced with adaptive rowing.

To answer the original question, yes, we did extensive testing of the chain and lubrication options in the mid- 1980s when we went from the Model A, which has a 1/2" pitch bicycle chain, to the Model B with the 1/4" pitch chain that is still being used on the current rowers. Accelerated wear tests w...

Socks only on the RowErg!

Try tightening the two screws that hold the generator cover on. If these have loosened up then the generator assembly can move and vibrate as it interacts with the flywheel magnet.
