About O’NEAL
Since the early days of motorsport in the 1960s, O’NEAL has helped shape performance riding gear. Founded by passionate rider Jim O’NEAL, the brand was built on one goal: create better equipment for riders who demand more. That same drive led O’NEAL into the mountain bike world in the late ’80s, bringing rider-focused innovation to MTB products across Europe and the USA.
