At the risk of being redundant, I just can't express how impressed I am with riders like this. The control it takes to balance that bike is amazing.
I'd like to think that I'm always riding with about 10-15% below my capabilities. If I get into a pinch, I can use that 15% to react and do something meaningful. Sometimes I think I'm fooling myself. Riders like this on the street have TONS in the bank. They don't target fix, and if they do, they catch themselves instantly, simply push the inside bar, and around the target they go.
I wish I could ride a little like that, but for non-show-off reasons.
