difference of model d year 2004 and 2015.

[fulham]

i had a concept2 model d 2004 model.
i have sold it to a friend .

could u please tell me what are the differences of the new 2015 model?

i can see it s black. and it has a new monitor called pm5. mine was a pm2 i think.

does it have heart rate ?

my 2004 model was very hard to sepereate the machine to 2 pieces for storage. maybe it s easier now.

is flywheel and damper %100 same with my 2004 model?


i can purchase the new one . i want to hear the news from u friends.

thank u very much

There are allot of internal and subtle differences.

Things like the chain guide rollers are different material, the footstretchers are different you probably had the PM3 monitor which was revised in 2007 to a better version of PM3 and obviously the PM5 has been released now. The PM5 is not necessarily a better monitor, it depends on what features you use, the PM4 and PM4 has everything I need including heartrate and PC connectivity to RowPro.

If you had a PM2 monitor then you had the Model C rower and not a Model D. The PM2 still had heartrate and all the critical information you needed.

The flywheel has not changed much but the damper is a better setup on the Model D and its easier to disassemble to clean now.

There were big steps from the Model A to Model B to Model C but the model D was just an evolution rather than a big step from the Model C. Essentially you can change a Model C to a D from a "Feel" point of view by going to a quiet kit and a new chain.

The newer black Concept 2 is a really nice Erg.

thanks for reply.

mine was a model d with pm3. i remember now. not c.

i think it s worth upgrading to model 2015 model d .

Depends on whether you maintained your rower or not, My Model C feels the same as the day I bought it in about 2001. Apart from it now needing a new shock/bungee cord, if you keep the slide clean and lube the chain and internal chain guide rollers the Concept 2 basically goes forever.

I'd say the biggest difference is the model D changed to having the nickle plated chain a few years ago (which is something you could do with older model Ds just by replacing the chain).

Why would you sell your rower if you plan on buying a new one? You know these things pretty much last a lifetime right? If it felt crappy rowing on it, it's because you failed to do maintenance or replace parts that are worn out (seat rollers, shock cord, chain/sprocket), and that problem can be easily fixed by doing said maintenance.

Read up on PM 5 problems before you buy.

I purchased my Model D in October, 2003. Model D's were first introduced in July, 2003 and were updated in August, 2006. C2 states that those updates included "modified monorail artwork" (which to me is meaningless), "redesigned foot stretchers" (the ones on my rower seem perfectly okay), and "updated frame lock mechanism". I admit that as far as convenience goes, the new frame lock mechanism is an improvement over mine. The one on my rower consists of a circular wheel in contact with the bottom of the monorail at the front and is quite satisfactory--as long as one is sure that the wheel is contacting the monorail as solidly as possible. Unlocking it takes a little effort, pulling on a cord connected to the wheel. That to me is the primary difference between the early and later models and since I can lock and unlock the halves on my early Model D without much difficulty, even that improvement doesn't seem to be a major one.

There was a problem with metal fatigue on Model D's produced for a few months after August 2006, but Concept 2 came up with a reinforcing kit to correct it, and that's no longer a problem.

As Carl Watts has said, the Model D was more of an evolution rather than a major change from the Model C. The Model D also evolved from its 2003 to its 2006 forms and that evolution seems to be even less apparent than the changes from the C to the D. Model D's produced from July 2003 through August 2006 continue to be excellent exercise machines. The only maintenance I've ever done on my 11 1/2 year old rower has been cleaning the monorail after each use, periodically oiling the chain and cleaning the flywheel cage, and replacing the top seat rollers twice. The newest seat rollers seem to be of higher quality than the earlier ones and have lasted considerably longer. Also, compared to the Model C I purchased in 1997, my current Model D is considerably quieter. I have heard no mention that the latest Model D's are any quieter than mine.

Aside from upgrading to a PM 4 or PM 5 monitor (my PM 3 isn't as good as they are, but it's okay for my purposes), I can't see how a rower can be any better than the one I have.

You've never changed the chain?

How many meters / year do you do on it?

You probably have the old chain which isn't nickel plated. The gym I go to has one of the model Ds with the old chain and it's rusted to hell because they never oil it.

The only things I would do if I had your machine is change the chain to the new nickel plated one, and get the heart rate monitor upgrade for the PM3.

If you keep the chain lubed you never actually need to replace it.

If you work out the power going into it its next to nothing for the size of it, even rowing at 800W is not really a strain. Its not operating in a dirty environment like the chain on a bicycle so it pretty much lasts forever if lubed.

Of course the average user doesn't do a thing and then things get ugly, especially those chain guide rollers inside the chassis.

You need to open it up to oil those?

I oil the chain itself like once a month.

[Carl Watts]

No not really there is a plastic cover underneath that can be slid out the footrest end.

It tends to catch on the two screws holding the leg on (probably intentional by design to hold it in place) but if you press up and pull it just slides out.

The two guide rollers are just plain bearings and yes they can last a very long time but mine started to squeak eventually and some oil that's supplied with the rower or just some engine oil will do the trick. I use a full synthetic oil in the car so obviously its pretty good.

I have heard stories of the guide rollers ceasing up and then the chain just cuts them in half and starts sliding round the steel shaft. The noise it would make would be something else and alert you to the problem straight away but I guess it was in a Gym with the music turned up !

I try not to get involved in the mechanical side of the rowers and am only interested in repairing the monitors, however the only Model C I did service the chain pulley was flopping all over the place and the nylon was spinning on the bearings. You definitely want to keep an eye on these on an older rower.

[f2d]

Hm, sounds like something that'll be a bit of a pain in the ass to deal with.

I'll probably do it yearly

I upgraded from a 2008 Model D to a 2015 because I wanted a PM5. Due to the amazingly high resale value of used machines it cost me around $20 more to get a new ERG than buying a PM5.
