Oisin
O'Callaghan

Oisin O'Callaghan is one of the fastest men on two wheels, full stop. The 2025 Irish national champion is nigh untouchable on a downhill back on his best days, and he has joined Trek-Unbroken DH with the explicit goal of getting back on top of a World Cup podium after winning in Snowshoe in 2023. He also has a very good dachshund puppy named Alfie. Both love to shred in their own way, though we're partial to the one who will still leave your furniture intact.
