Ronnie Renner

FMX

One of the great personalities of freestyle, Renner matches his stellar riding skills with break-dancing routines and hilarious interviews. Over the last few years he's backed away from freestyle progression and no longer competes in Freestyle comps, instead focusing on demos and crazy World Record attempts (he jumped nearly 65 ft out of a quaterpipe, breaking his own record, in 2009). But there's one comp he embraces: XG Step Up. He's a favorite to take another gold this year to match his first-place medals from '07 and '09.
