Last weekend, a big bicycle fair Cycle Mode was held in Osaka. In this event, an interesting flatland contest took place. Some Japanese BMX shops - such as Hommage, Reality, Guell - formed teams with two of their supported riders and battled the other teams. The final battle was Spaceark team representing west Japan vs Slopshot team representing east Japan. After a great battle Slopeshot team consisting of Moto Sasaki and Koichi Higo won against Shinichi Russia Kiba and Masashi Itani.
