Uneven Track Wearing

[[old] cityeast]

I have noticed after nearly a month of using my brandnew model D that the roller track wear marks on the contact surface of the slide appear more pronounced on the left side, especially in the forward part (catch area). I seem to also get the feeling like the left cheek sits a bit harder on the saddle than the right side. <br><br>My erg seems perfectly level in all directions. I have noticed that the retaining rollers (underside) has more play on the right side than the left. <br><br>Is it me or the erg? Or both? I must confess that on my roadbike I also don't feel perfectly symetrical on the saddle, but the other way (right side seems to sit harder than the left).<br><br>Oh yeah, and I consistently clean the rollers and slide after every use to ensure no foreign objects get stuck to the rollers.

Most college rowers were either "starboards" or "ports", and tend to reach farther with one arm than the other, and it establishes habits that are not beneficial to scull-type form (an even, semetrical form). As a starboard rower, my right leg, arm and core muscles were visibly larger and stronger. Maybe you are favoring one side and causing a similar effect. <br><br>Erg in front of a large mirror, straight ahead of you and see if you notice a form imbalance. I erg beside my wife's car in the garage (the clean car), and watch my side-view form periodically from time to time. A little self-coaching is a good thing.

Well, after 400,000m on the odometer, I am not 100% sure this is me.<br /><br />Here are the pics. The left side of the track is definitely wearing more. <br /><img src='http://www.australis.ch/images/track.jpg' border='0' alt='user posted image' /><br /><br />But here the thing. There is almost no play on the right side between the grey main rollers and the retention roller (little green one). However on the left side (where the wearing is occurring) there is about 2mm of play. It has been that way since new. I assumed this is acceptable tolerance. <br /><br />Here is a picture of the front rollers:<br /><img src='http://www.australis.ch/images/rollerfront.jpg' border='0' alt='user posted image' /><br /><br />Here is a picture of the back rollers:<br /><br /><img src='http://www.australis.ch/images/rollerback.jpg' border='0' alt='user posted image' /><br /><br /><br />My real problem will occur if I ever have to try an explain the problem to the local distributor. My german is not that good

You could also post a picture of your posterior and we could tell you if one cheek is bigger than the other

Well I tried to take picture of my posterior, but I couldn't find the right angle!! <br /><br /><br />But seriously, why is there more freeplay between the main/retention rollers on one side than on the other?

Hi cityeast, I wouldn't worry too much about this as everything you have said and posted seems normal (within tolerance). If you want to try to even things out between the left and right, try loosening the the two large nuts and bolts that go through the top rollers just a couple of turns. Then retighten them with some weight on the seat. JonW

Cheers. Will give it a try when I get the chance to dig out my tools, and I will let you know how it goes.
