Rockstar Games is hosting this year's Harlem Skyscraper Cycling Classic on June 20. Of course that means that there will be an eclectic sampling of pop stars tooling around Marcus Garvey Park come Father's Day. Among those riding the .75 mile track for the $15,000 prize will be Olympic Champion Walter Perez of Argentina, four-time World Champion Franco Marvulli, German track racing stars Leif Lampater and Christian Grasmann. The event will also include performances by hip-hop icons Biz Markie and Mister Cee. Hey Houser, we want pics of your fancy bike!
