London Bikes is working on a signature handlebar for James McGraw. Above is a photo of the prototype. It's called the King James Handlebar and below are the specs and a comment from James.
Specs: 8" tall, 25" wide, 2 degrees up, 2 degrees back sweep.
"Honestly these bars feel incredible I don't feel so much flex in nose wheelies they felt right immediately I did not even have to get use to them I truly rode as good and some tricks better as soon as I put them on." - James McGraw
