Oisín O'Callaghan Returns to Trek | Sleeper Collective Mini-Doc

When Oisín O'Callaghan was in primary school, he wrote that he wanted to be a world champion mountain biker. Not a footballer. Not an astronaut. A world champion mountain biker. Now the Irish downhill racer is back with Trek-Unbroken DH, turning heads on the World Cup circuit and making that childhood prediction look less like a dream and more like a plan.

The new video from Sleeper Collective drops you right into the green, foggy hills of County Limerick, where O'Callaghan grew up riding the Ballyhoura trail system.
