Concept2 Forum

Welcome to the forum, Fred.

If you don't get much feedback here (there aren't many Dynamic users out there) then I'd definitely give C2 a call - they've always been super-helpful when I've called them with questions.

Good Luck

I'll second what has already been said - for me the straps are 100% superfluous, and I never use them. (also, if you find that you HAVE to use them for anything less than a super, super hard effort that means that you probably have an issue with your technique). In your case I would strongly recomme...

For a short time after submitting a post it can be edited, but after a while (don't know exactly how long) that option goes away and it's cast in stone.

The only bearing moving at that part of the stroke is the flywheel bearing.

Which might explain why it doesn't do it on the drive - the flywheel bearing is locked up at the clutch and not moving relative to the axle.

Bottom line - I'm putting my money on the flywheel bearing as the guilty party.

Any tips to switch to 2 breathing cycles on one stroke?

This is what works for me:

First, the easy part: one full inhale and exhale during the recovery.

Second: a relatively quick inhale just before or at the catch, and exhale on the drive.

You might have lost a balance weight, but I would think that would result in a 1 / rev response at all rpms. Right now it sounds like the flywheel is going through a resonance as the rpms decrease. You might not see it on the way up because you go through that speed range too quickly or because of t...

Welcome to the forum.

Is the issue purely a noise, or is it both noise and vibration?

As you've probably already figured out, the seat rollers are easy enough to replace, so no big deal there.

since at races you cannot display the drag factor

I'm not a racer, so I have no first hand experience, but I've never heard that before.

Any suggestions are very much appreciated, TIA. 1) Did you check the C2 web site? (see link below) They have lots of helpful information. https://www.concept2.com/support/indoor-rowers/model-c/troubleshooting 2) If all else fails, give them a call (or send an email) - they've always been super-help...

The chain would be the simplest to examine, but as far as dramatic changes in how it behaves, noise level might be the best. Also, damper lever position vs drag factor could possibly tell you if they cleaned it. Finally, some places will return the old parts they removed. If all is well I would not ...

Does anyone know how they are supposed to be attached/have any suggestions on how best to re-attach them?

Welcome to the forum!

If all else fails, give C2 a call - they're super helpful, and try their best to support their very old products as well as they do the newer ones.

Good Luck

I'm one year younger than you, but have learned the hard way to increase my pace in small increments over extended periods of time. There really is no rush at all...

Best of luck with your recovery.

Paul, you may want to repost this in "Health and Fitness" sub-forum - it will surely get more attention there than here in the "Oars" sub-forum. Good luck with your hip. Hi. 5months since r.hip resurfacing op. Allowed 10mins v light rowing now ie 16spm @ 2.40/500. Has anyone else had same op? Also c...

Congratulations - it sounds like you were both lucky to match the mass of the original and did a good job.

I wish I knew more about them (Purpose Trusts) and unfortunately, reading the description on Wikipedia didn't help much. Nevertheless, it does sound like it's good news. C2 has always struck me as a good company in more ways than one, and when I bought my Model C from them ages ago, and when I buy s...
