Rudy, your point is/was clear. As the saddle moves fore/aft, you are effectively shortening the top tube, no? If you want to run more/less aggressive positions then, you would need to swap stems out to offset the amount of change in the saddle postion. Unless you go with the method I suggested earlier, where your arms would move fore/aft over the arm pads, and the adjustable handles would still leave the handle in the right spot. Of cours,e though, that wouldn't be ideal.
Yes, as you move the saddle fore and aft, you're effectively changing the top tube length.
Yes, if you deliberately wanted to change the position where your arms will rest, the length of the bar will also need to be adjusted accordingly. But that's a huge change.
If you're thinking that by moving so much more forward without changing the stem and shortening the effective top tube, which may put you in a more upright position, thus less aerodynamic, then, yes, you're right.
But what about the height of your bars? what about your knees position? too far forward may not be a good thing. there's just so many factors to consider though.
But you know....if you know the exact position that you wanted to be in, you can measure the aerobar and get one that size. The airstryke in this scenario would really help you if you don't already know what you need as far as position is concern. I guess from a pure Time Trial perspective, a little extra weight wouldn't matter.
For me, comfort is power. But if you can accomodate such aggressive position for a long time trial, then more power to ya
Like I said, the LBS owner who fitted me, he sets up on a very aggressive position where the arm pads are more toward his wrist........whew. I don't see how he can control his bike from this position and he's a certified fitter ..lol. the dude charged me $80 for a fitting session.
If you look at Lance, he's not like that. His' back is relatively flat, elbows ALMOST 90 degrees, his back keeps a parallel position and so is his sternum, with the ground and he kicks a**
Aztec, are you just now getting into TT? and trying to find out your fitting position?
