The size of the erg: One size fits all ?

Hello,

How is it possible that different people can use the same erg ?
I myself am 1.78 meter.


I mean when one buys a bicycle, there are bicycles in all different sizes and a bicycle can be adjusted.
Since I am rather average, I do not think it poses a problem for me.

I would think the limiting factor would be the length of one's legs. I am the same height as you and have more than a foot of rail left at the end of my stroke so one would have to have extraordinarily long legs to run out of rail.

The foot rests are, of course, adjustable

This has been pointed out before but has not been comprehended.

Two important adjustments to make would be capability of (1) raising or lowering the railing in back and (2) raising or lowering the fan cage in front.

As it is, the cog wheel is currently the same height above the railing for everyone, whether 6' 9" or 4" 11" it makes no difference to C2. Nevermind that the resulting physiological angles are totally different.

I'm pretty sure there is a longer rail available!

Happy rowing!!

I've seen pictures of NavHaz on his C2 and it is definitely a scaled down version! :shock: :wink:

Wasnt there someone at crash B's that had to use a different slide because his legs were so long (I think he was like 6'7" or something).

The longer rail certainly exists, but I can't recall ever seeing a spare rail, as if the longer had been substituted for a tall competitor, layign about at WIRC. It's possible the organizers just hid them well, but there aren't that many places to hide things like that.

Pretty sure that tall competitors like Pavel Shumei and Jamie Schroeder just used the standard Rail length and get very close to the end.

As far as the effect of cog height and seat height are concerned, the handle moves very freely to fall exactly inline between the shoulder and cog, so why anyone would suggest that this needs to be "addressed further by C2", is a mystery. I've worked with small children, less than 3ft tall on the Erg, as well as Athletes over 6'5" and they all were able to work easily within the normal dimensions of the Erg. Perhaps those under 2 feet tall or over 7 feet would need a bit of customization. Or they can pick a different sport. :wink:

The cogwheel is in the middle of the fan cage, not sitting on the handle. You can lift the handle up and down, but that does nothing to move the position of the cogwheel. Even if it did, a 6' 7" male can lift the handle higher than a 5' 1" female, which is exactly the point, as the angles and lines to the cogwheel above the railing are different.

I'm sure if you're a 6' tall 250 pound male, it doesn't make any difference what happens to a 5' 1 95 pound woman, as long as the machine fits you, so they may as well use the same sized machine and stroke rate that you do.

However most of us can see that all reaches, weights, heights, inseams etc, are not the same. Much of these are already accounted for and adjusted in boats. Why is that done or do they have it all wrong. Of course in a boat you couldn't row if everyone had to use the same settings. Unless everyone was the same height and same size.

As usual, you show that you know nothing of rowing boats, have you ever even been in one? Thought not. Foot Stretchers can be adjust fore and aft, but that is not required on the Erg, as there is no "work through" or handle angles to worry about. Height of work can be adjust within a narrow scope, however that has also to do with the placing in and extracting from the water of the blade, not something we are concerned with on the Erg. Oar length can be varied, with an effect similar to adjusting the Drag Factor.

What does weight have to do with the Erg being designed for a person?

Why are you following me around the forum and trying to insult with your gibberish?

John, you are quite the cheeky bitch, for someone who has never competed in an indoor rowing event in your life. Sad little man trying to make yourself feel big? Perhaps you could be a coxswain. Add that to your "Life Coach" credentials, though it's probably much more significant.

Over and out! Unless you want another round of "JohnnyBall". You've been reduced to a babbling fool over the last several years of play, the best part is that you don't even seem to know it.

The all time open champ, Matthias Siejkowski, is 6'9'' and I have never heard of him having a problem.

at crash-b's this year at BU, i volunteered in the warm-up area. There was a guy that needed a longer slide, and we switched it for him during his warmup. he used it during the race too, he was a masters i think, probably about 6'6'' or 7''. the slide was only 2 or 3 inches longer, but i guess it made the difference.

So, it does get done, just very efficiently by the voluteers.

Would you be aware of all of these instances? how many longer rails are on hand?

Thanks for providing the information.
