Found while searching the vast internet:
Speed = (RPM x rear tire circumference x front sprocket) / (primary gear ratio x selected gear ratio x rear sprocket x 1056) Is this correct? Where does the "1056" number come from (IMG:style_emoticons/default/confused24.gif) This is different from the automotive one I have: Speed = (RPM x rear tire circumference) / (R&P x selected gear x 336) |
