Kahuna
It’s called the Kahuna for a reason. This bike is the king of our classic hardtail lineup and it’s often the bike that makes people realize how awesome a mountain bike can be. With its confidence-inspiring progressive geometry, 29” wheels, 100mm suspension fork, and internal cable routing for an optional dropper post, the Kahuna is at home on your local singletrack or flow park. The Kahuna features nice touches such as a 12-speed drivetrain and powerful hydraulic disc brakes. It’s the bike that’s ready to get you to the next level!
“Kona further refines the Kahuna, resulting in superb ride quality, intuitive feel, and a fine-looking hardtail mountain bike.” -Bike Radar
