Engineered as the ultimate drop-bar off-road adventure bike, it features an exceptional Chromoly (CrMo) frameset that's strong, agile and amazingly comfortable for off-road riding and long days in the saddle.
This versatile adventure bike is equipped with a SRAM 1x11-Speed groupset, which features a wide-ranging 11-42T cassette for climbing with ease while Rival hydraulic disc brakes control your momentum on the descents in all-weather conditions. Also, it rolls upon Formula hubs, WTB Tubeless Ready rims and Maxxis Recon Race tyres, giving it a fast, stable and high-grip performance on any terrain.
Very few materials offer as much shock absorption, durability and supple-ride characteristics as steel. Kona has never strayed from cycling’s original material and has worked tirelessly to adapt, refine and innovate Kona Chromoly 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.
12mm Thru Axles:
12x142mm, 12x148 and 12x157 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 12x148 Boost standard in the mix. Boost spacing provides more tyre clearance at the chainstay yoke, while the rear wheel is stiffer and more durable relative to a 12x142 thru-axle.
Tubeless Compatible Rims:
Tubeless rims allow for tyres with more puncture resistance; the ability to run lower tyre pressure, which provides better tyre grip on the trail; lower rolling resistance; and weight savings over traditional tube and tyre systems.

Quite often it’s the simplest innovations that enable the greatest improvements.<br><br> With offices in Vancouver, BC, Bellingham, Washington, and Geneva, Switzerland, and a staff that lives and breathes riding bikes, today Kona is perhaps best known for its blend of modern technology and creative thought. One of the most notable innovations of 2014, one that garnered them an incredible amount of attention, was the simple idea of rider fit, best viewed in the geometry and design of their incredibly successful line of Process enduro bikes.<br><br> A lot of the company’s most noteworthy technology comes in the form of its undying attention to detail. From steel to carbon fiber to titanium, refined aluminum alloys through to Scandium 69, Kona features perfected bicycle models ranging from Kids’ cyclocross bikes to World Cup downhill race machines, stylish inner city commuters to flat-out, perfectly priced road bikes. Still owned by its original founders, Kona is one of cycling’s great success stories.
