7005 Aluminium - Aluminium is one of the most widely used tubing materials in the bicycle industry. The material is mixed with other elements creating alloys with different ride characteristics and properties. Kona uses butted 7005 Aluminium extensively throughout our entire range of bicycles. A tough, durable, affordable, light and dependable alloy, 7005 delivers great riding performance for years and years.
Hydroformed Tubing - Hydroformed tubing is a forming technology that uses a liquid to form the shape of a tube and align its grain structure. Kona use hydroformed tubing on a variety of their bicycles. Quite simply, the technology delivers on sound structure and ride performance like no other tubing in the world. The process results in a seamless, continuous, aligned piece of metal-right down to the fiber structure itself.
Hydroforming proves especially advantageous at weld points where it can be flared to increase weld areas, essentially, adding strength without adding weight. The result is a strong, flawless frame with great lateral stability, durability and responsiveness.
Sloping Top Tube - As the pioneer of sloping top tubes in mountain bike frame design, Kona have stayed true to all the many positives this design technology brings to the trail. First, it allows the top tube to be longer, providing more room for correct positioning and free body movement. Second, it also allows for more standover clearance, critical on dual suspension bikes due to a higher bottom bracket. Vertically, the frame is more compliant, allowing it to absorb more shock than frames with horizontal top tubes. It also puts the rider in a more secure position for downhill sections of trail.
Internal Headset - By having the headset bearing located inside the heat tube, rather than the top and bottom, you're able to achieve a whole array of advantages when it comes to front end stiffness and overall performance. With an internal headset, the head tube is able to take the stress directly, resulting in less play, stronger, improved ride characteristics, and better bearing performance. Basically, like a good friend, an internal headset is sharing the load, every molecule in the materials taking the load more equally.
Compact Rear Triangle - Short chain stays and seat stays provide a perfect balance of stability and power transfer when out of the saddle and hammering. Shorter seat stays also have less deflection during braking and accelerate quicker than longer stays. |
