I am looking for 30mm risers for the AS. My upper back has shooting pain after about 30 minutes and my arms are straight while riding- I can't get far enough forward on the seat without putting the boys on the tank. It feels like if I had the handlebars more toward me it would help. I saw the 20mm touratech piece which I know works without moving cables, but would a 30mm be pushing it? There are a few SW motech 30mm pieces left floating on the internet.
