Kona Kahuna 29" Mountain Bike 2020 - Hardtail MTB

The Kahuna is the bike for the person who is ready to get serious about riding singletrack but doesn’t want to spend serious cash. We’ve updated the geometry for 2020 to allow for greater tire clearance and better overall handling. The Kahuna is outfitted with a 1x SRAM SX Eagle drivetrain, RockShox suspension, powerful Shimano hydraulic disc brakes, and fast-rolling, tubeless-ready WTB 29” rims. The Kahuna is the complete package!
KONA RACE LIGHT 6061 ALUMINUM - Kona Race Light 7005 and 6061 are lighter, more performance-oriented fabrications of our 7005/6061 tubing. Designed to meet Kona’s discerning race specifications, Race Light 7005/6061 are custom butted to create thicker tubes at weld areas and important parts of the frame, providing incredible strength and torsional integrity to the feel of the ride. We remove wall thickness in other parts of the frameset to lighten up the bike, giving the perfect balance between quickness and stiffness.
INTERNAL HEADSET - Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible.
TAPERED HEAD TUBE - More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it’s needed.
TUBELESS COMPATIBLE RIMS - Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems.
Occasionally, without notice, manufacturers change product design and/or specifications.
