Kona Mahuna 29" Hardtail 2021

The Mahuna strikes that perfect balance of mountain bike and all-around fun rig. Its 29” wheels easily roll over obstacles and provide a smooth, predictable ride. We’ve upgraded the fork to a 100mm RockShox Judy Silver and beefed up the brakes to Shimano hydraulic disc brakes. A Shimano 11-speed drivetrain makes quick work of tough hills ensuring the Mahuna is as fun going up as it is going down.

“Kona made some really smart spec and design choices…that come together to create a responsive, eager ride...“
