The first is pretty obvious, if you don't have your ass firmly on the seat, it let's through rear wheel lift in response to the front brake force. Once that begins, the geometry changes, and less force is needed to continue the roll.
The second is vertical different. The bike weighs between a fifth and tenth
I cant imagine that I had lifted off the seat at that moment. But maybe I have too much weight on my hands on the bars?
I am thinking of removing the extended stem 140 and putting back the original 120, then adjusting the seat back by that much. I am comfortable with the current setup, no knee soreness (took some dialing in to get that), I do tend to slide back on the seat. Maybe even 20mm would change the geometry a bit?
Would weighing the front wheel and rear wheel with me on the bike give me an indication of my weight distribution on the wheels?
