Complex Says: Dennis could easily be number one on this list, and we'd be completely cool with that. He can ride everything. He's arguably the gnarliest rider out there right now. The level he's taken bike riding to is at times completely death-defying. He can hang at any dirt jumping comp. He won best video part this year for the Last Chance video. And he won ramp rider of the year.
