OK.. So the new GT is everything I was hoping it would be. And that is cool. However I'm having an issue with handle bar height and then seat height.
At first with the neck at the factory rise, the seat was great but my finger tips were going numb. So we raised the bars a bit (1\4 inch). Now my fingers no longer go numb, but nothing I do makes the seat feel right. It's either canted too far forward or back and its either too high or low.
Can messing with bar height really be driving all this weirdness?
I always set my seat height 1st, that is the most important thing.
I set my seat level using a small level at the middle of the saddle and set the fore-aft position so the ball of my foot is just behind the pedal axle for more pedaling torque.
My saddle is about 4 inches higher than my handlebars which gives me a better aerodynamic position and more control (I am pretty flexible and have a strong core).
You should never use the handlebars to support your upper body, this will make your hands go numb quickly.
I also place my hands on the bars so the outer heel portion of my palm is on the bar, never in the middle of the palm which can affect your ulnar nerve.
Keep your feet heavy on the pedals and keep your hands light on the bar.
It can sometimes get frustrating getting your bike dialed in for your riding style.
