Thanks for the link.
"It handles far better than the old bike, much more controlled, and the large 19inch front wheel almost feels like a 17."
I am not sure what he is noticing there - it is hard to imagine the wheel is any lighter, given the wider tyre, and so it should steer just the same given similar geometry. But he's noticed something, and liked it.
A lot of it might be simply tyre construction and profile. Can make a huge difference.
