ABOUT

Oisin O’Callaghan, also known as Double O, is a 22-year-old Professional Downhill Mountain Bike Athlete from Limerick.

Oisin found his love of riding at the young age of just 3 years old. He grew up completely immersed in the sport. Riding every single day and building his own trails...

(he even dug up his back garden)!

As a young boy, Oisin dreamt of being a World Champion.

By the age of 15, he caught the eye of professional team, The YT Mob. Then, in 2020, at the age of just 17, Oisín claimed Ireland's first-ever rainbow jersey in a Mountain bike discipline.

HE BECAME A WORLD CHAMPION.

But it didn’t stop there…

In 2023, he was the first-ever Irish World Cup winner in an elite mountain bike category.

TODAY, OISIN IS THE 6TH FASTEST DOWNHILL MOUNTAIN BIKE RACER IN THE WORLD.
