This is where the rubber meets the trail. The Big Kahuna, with a 27.5-inch-plus tire and playful geometry, makes as much contact with the dirt as possible. The entire Kahuna line is already known as a worthy singletrack shredder, and by giving this bike a bigger footprint, we’ve made it more capable than ever.
