Matthias won the first official UCI Flatland World Cup event ever followed by Viki and Alex. Congratulations! The UCI doesn't provide a ranking on their website at the moment but as far as we understand the FISE Jeddah didn't count towards the World Cup and Hiroshima was the first official event.
Check out Matthias' final run above. The complete finals are available here.
