Given my current thoughts on bike positioning and handling, it's absolutely mind-boggling that you can go through a corner at all set up like that. Your saddle is basically directly over the BB, your rear foot is entirely behind your butt, and your biceps are angled negatively (0* representing perpendicular to the ground).

Don't take this the wrong way. I've seen your videos and have seen for myself that you have no trouble taking a corner.

Your bike is setup very much like a cat 1-2 tt bike. (Pros must abide by the saddle/BB rule).
