This Kona classic brings some of the finer things to light. The Fire Mountain is running the new Microshift Advent 9-speed drivetrain to keep things shifting smoothly and hydraulic disc brakes to stop on a dime. With adjustable 100mm of Suntour suspension and sturdy WTB tires aboard wider 27mm rims, the Fire Mountain helps build confidence off-road. Available for smaller riders in a 26-inch wheeled XS version and a 27.5-inch wheel for sizes S-XL.

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.

27.5-inch 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.
