Re: PM5 cadence spikes in recorded workouts

Pausing during a workout, especially if the pause is more than 5 seconds, will almost always result in an abnormally high or low stroke rate value. When you say it occurs "immediately after the end of an interval" what type of interval workout are you doing? Does the anomaly ever occur when you are ...

Did you pull the LCD off the board and clean both sides of the zebra strips, the board and the lcd contact areas? C2JonW

Re: Model A sprocket clutch not engaging

The ratchet and pawl clutch in the gear cluster has some very light duty springs to push the pawls into the engaged position. The lubricant in the mechanism has a tendency to thicken over time, to the point of overcoming the springs and sticking the pawls in the disengaged position. So you need to f...

Re: Setting drag factor

Presumably manual recalibration will take account of dust or any other air blockage and can restore accuracy. No not any other air blockage. Some dust buildup shouldn't be an issue, but an excessive block such as a towel over the flywheel will likely put things out of normal operating range. C2JonW

Re: Concept 2 Model D old vs. new difference in rowing

A few facts from the production side of this- Moment of inertia is corrected to within +/- 4 grams at the rim of the metal disc. Balancing tolerance is +/-.2 grams static and +/- 1 gram dynamic, also measured at the rim. The number of weights and/or holes is only an indication of how out of balance ...

Re: Type of oil for the rower chain

Jon, I am unfamiliar with the term "20 weight". Is this a locally used term in your country? I'm referring to SAE20 oil. The Society of Automotive Engineers came up with this method for describing the viscosity of engine oils- pretty sure it's an internationally recognized system, and for ambient o...

Re: Type of oil for the rower chain

It's not that I want to ignore him, but I live in a (third world) country without a Concept 2 agent and without easy access to stuff that's commonly available elsewhere. The shop that sold me the Concept 2 came in a few months ago to oil the chain and left a huge mess so I prefer to do it myself. I...

Re: Type of oil for the rower chain

People tend to overthink the oil for chains. Job #1 is keep it clean, job #2 is a light smear of almost any clean motor oil. I use Marvel Mystery Oil myself :-) MMO is meant to be primarily a fuel additive and may be better than nothing- according to Wiki it's mostly mineral oil, though there's als...

Re: Type of oil for the rower chain

I would think that any bicycle chain oil would be fine. the rower is not subjected to the elements nor the gear change abuse that a bicycle chain typically has to endure. Just don't use WD-40. That is not a lubricant. Yes, you would think- but many bike chain lubes are not suitable for the rower- t...

Re: Type of oil for the rower chain

There are many chain "lubricants" available and we have only tested a few. Many of them are primarily a solvent for cleaning, and once the solvent is gone there is very little lubricant left behind to do the real work, which results in premature wear and elongation of the chain, which leads to early...

Re: blips on power curve not down to stroke

What model rowing machine and PM? Firmware version of the PM? A screen shot of the blip would be helpful.
