Okay folks, I think I've got this thing figured out.
First, again, thanks to all who commented.
Lowering my handlebars all the way down has helped a lot. Much better. More arm room, etc.
I think I know, not counting the bars, where my biggest problem was. I was trying to emulate what I had seen in this picture, which is of someone on an RS.
Instead of someone riding a GT.
To my eye, there is a difference. The RS rider is leaning forward a bit more than the GT rider. I was trying to lean forward too much.
With the handlebars lowered my hands reach the bars just slightly above bar level. That is, I am not reaching up to grab the bars, but coming at them from just above the bars.
My arms are not parallel with the ground, but angle slightly upward from the bar to my elbow.
Placing the foot so the area just behind the ball of the foot is on the pegs has made a world of difference. Thanks for that advice.
About the "hunch" in my back. I'm afraid that's just part of my anatomy. Years ago I raced at our local velodrome. Track bikes, fixed gear, no brakes, etc. The position was leaning forward and as low as you could go. All the other riders backs were razor straight, but I always had a slight hunch in the upper part of my back. I could throw my chest out to Cleveland, but that anomaly of mine would still look the same. Funny, but I had forgotten all about that, since riding on a Harley it's almost a natural look.
I won't bother you kind folk with any more videos, but I think the combination of a low seat, foot position on the pegs, and lowering the handlebars was just what I needed to do to be comfortable on the GT. And, it is a great bike.
There are a few more questions about riding the GT in regards to using your knees to steer rather than countersteering, or is it better to use the foot pegs, or a combination of both, but I'll save that for another thread.
I can't thank you all enough for your patience, and willingness to help a fellow rider. This is a great community.
