Ran 66/60 today,Very responsive and noticeably faster up/backshift.It flat Rocked on a climb however on WOT across lake it over reved so will run the other angle 66/62 next.Also will need to add some Pin weight and had to click down to [#1} I have the Half /clickers.Very happy with performance and extreamly quick reacting.Rpm,s were solid even when getting air on steep hill at 40 mph. no drop at all.This is on a SHR 860.
