Yup, almost impossible to set up Sphincters to fit with in the rules. Though the "The area of the point of support of the hands on the handlebars is defined by the diagram below:" makes it a little ambiguous (you could maybe argue the point of support falls within the box, even if the entire bar doesn't). Doubt you'd ever get picked up on it unless you race anything big.
