MAJOR JAKE

KONA CARBON COMPACT REAR TRIANGLE INTERNAL HEADSET TAPERED HEADTUBE TUBELESS COMPATIBLE RIMS 700C WHEELS
Featuring the same full Kona Carbon CX Race monocoque disc-brake frame used in the Super Jake, the Major is spec’d purposefully towards the elite-level cyclocross racer looking to get into a carbon bike without breaking the bank. With superb ride characteristics designed to maintain stiffness during out-of-the-saddle efforts while still taking the edge off the rough stuff. With hidden fender eyelets and two bottle mounts for those winter-spring wet training rides, the Major Jake is the ultimate cyclocross workhorse.

TECHNOLOGY

CYCLOCROSS

Here at Kona, we love cyclocross. It doesn’t matter whether you’re a leg-shaving skin suiter or a wool-ensconced commuter, we make a ‘cross bike to fit your demands. From the top down we incorporate race-inspired geometry with neatly tucked-away amenities like fender mounts, rack, and water bottle mounts. In short, our CX bikes are designed with ulterior motives in mind. The course tape is just a reference and we’re not afraid to encourage you to color outside the lines. Go out and give ‘er! Just be back in time for dinner and wash your hands.

KONA CARBON

To create our growing fleet of Kona Carbon bikes our design team works intimately with our manufacturers to ensure the desired ride characteristics, durability demands and weight stipulations are met to the highest standards possible. Kona Carbon bikes are feather-light, super-fast, extremely durable and wildly fun.

WHEN DO WE CHOOSE CARBON?

The first step in the design phase is ensuring how carbon fiber can be optimized for its intended use. An increasingly refined and tested material, carbon fiber is the ideal choice when it comes to creating light, tough, playful bikes. While we’re selective when choosing carbon fiber for a given application, for certain models it provides that perfect balance of weight, strength, frame damping, stiffness, compliancy and durability.

DESIGNING THE KONA RIDE

It’s imperative that key elements of the Kona Ride come to life in our carbon bikes. Like with all of our designs, it is efficiency, agility, comfort, and overall strength that are key considerations. We work to leverage all the inherent properties of the material, which are markedly different than steel or aluminum. For our designers it’s crucial that our carbon bikes still feel, ride and last like a Kona.

SMART FABRICATION

THE WEAVE: Kona Carbon bikes use TORAY fibers, the most technologically advanced in the industry. Toray is the same weave used in Formula 1 cars. Our entire structure is built with unidirectional prepreg carbon fiber underneath a UD frame finish. The result is frames with industry-leading weight, stiffness and durability.

THE FRAME: Kona Carbon frames are built with a monocoque main triangle that allows continuous fibers at tube junctures, resulting in a stronger, lighter overall structure. Our production process also eliminates as much bonded-in aluminum inserts as possible. Kona Carbon frames are only molded with internal air bags, which are removed after the molding process.

TORTUROUS TESTING

During the prototyping process, our frames are tested on veritable bike torture machines that push our designs through tens of thousands of test hours. What we learn from this directly translates into making stronger frames, while eliminating unnecessary material. Kona Team athletes are next on the beat down list, but even after they’ve had a rigorous go, our product team steps on to abuse the same prototypes, day-in and day-out, usually through a cold and wet Washington winter.

COMPACT REAR TRIANGLE

Short chainstays and seatstays provide a perfect balance of stability and power transfer when out of the saddle and pedaling hard. Shorter seatstays also have less deflection during braking and accelerate faster than longer stays. A more compact rear triangle also helps the bike to negotiate tight-twisting sections of trail. The Honzo, Operator and Process 111 are good examples of 2015 bikes with incredibly compact rear triangles: quick, aggressive in corners, easy to maneuver and laterally stiff.

INTERNAL HEADSET

The major benefit of an internal headset, whereby the bearing cups are actually pressed into the frame and are easily removable, is the extra layer of protection it provides the bearings against the elements. Additionally, the bearings are commonly available angular contact bearings, which are easily and inexpensively replaced. 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 HEADTUBE

Aside from improving the aesthetic, due to its cleaner lines and smooth transition between the fork crown and the headset cover, tapered headtubes also offer a more solid interface between forks with tapered steertubes and the bicycle frame itself, thanks to more weld contact area. More girth at the bottom of the headtube better distributes shock force, prolonging the bearing life of the headset itself, eliminates brake shudder, all while providing positive 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 headtube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it’s needed.

TUBELESS COMPATIBLE RIMS

An increasing amount of 2015 Kona models feature the benefits of tubeless compatible rims. Tubeless rims allow for tires with more puncture resistance, better tire grip on the trail, lower rolling resistance and weight savings over traditional tube + tire systems. For 2015, you’ll find tubeless compatible rims on most of our XC Race Light and Enduro bikes, as well as throughout our Cyclocross and Road platforms.
