Very few materials offer as much shock absorption, durability and supple-ride characteristics as steel. We’ve never strayed from cycling’s original material and have worked tirelessly to adapt, refine and innovate Kona Cromoly framesets as rider demands continue to evolve.
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.
12 x 148mm Axle:
12x142mm, 12×148 and 12×157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. For 2017, you’ll see the 12×148 Boost standard in the mix. Boost spacing provides more tire clearance at the chainstay yoke, while the rear wheel is stiffer and more durable relative to a 12×142 thru-axle.
