KONA 6061 ALUMINUM
Kona 7005 and 6061 Aluminum alloys are used extensively throughout our fleet of mountain and asphalt bicycles. A tough, durable, light alloy, both Kona 7005 and 6061 deliver fantastic, reliable performance that lasts for thousands of rides. Much of our 7005/6061 tubing is butted and/or formed, meaning the tubing’s wall thickness can be increased or decreased, as well as shaped, so we can fine-tune a particular frame’s strength and ride characteristics depending on its intended application.
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.
27.5″ WHEELS
The benefits of the 27.5-inch wheel are simple: they roll over obstacles and track better than 26-inch wheels, but are more maneuverable and nimble than 29-inch ones.
LIFETIME WARRANTY
Register a new Kona bike within three months of purchase, and the original owner qualifies the Kona frame for a free Lifetime Warranty. Note: this does not apply to Kona Carbon models.

The original owner shall pay all labor charges connected with the repair or replacement of all parts.
LIFETIME LIMITED WARRANTY ON BICYCLE FRAME
When warranty on non-carbon Kona bikes and frames is NOT registered within three months of purchase, Kona warrants to the original owner that the frame of this new Kona bicycle purchased from an authorized Kona dealer shall be free of defective materials or workmanship for a three-year period. IF THE WARRANTY IS REGISTERED WITH KONA WITHIN THREE MONTHS AFTER THE PURCHASE OF THE BICYCLE, THE WARRANTY IS EXTENDED FOR THE LIFETIME OF THE ORIGINAL OWNER, with the exception of carbon bikes and frames. During warranty period, Kona shall repair or replace, at its sole option, the bicycle frame if Kona determines the frame is defective and subject to this limited warranty. The original owner shall pay all labor and shipping charges connected with the repair or replacement of the bicycle frame. Please see the Kona owner’s manual, provided with your bicycle, for additional information.
