KONA CARBON RACE
To create our growing fleet of Kona Carbon Race bikes, Kona has partnered with some of the most reputable carbon manufacturers in the world. Our design team works intimately with our production facilities to ensure desired ride characteristics, durability demands and weight stipulations are met to the highest standards possible. Kona Carbon Race bikes are featherlight, super fast, and tough as all hell.
STEP 1: APPLICATION
At Kona we are very selective when choosing carbon fiber for specific bicycle frames. Each riding discipline requires a different balance of weight, strength, frame damping, stiffness, compliancy and durability. With over 25 years experience making bikes for every known cycling discipline, the first step in the design phase is ensuring how carbon fiber can be optimized for its intended use.
STEP 2: DESIGNING AND ENGINEERING THE KONA RIDE
For the good guys and girls in the Kona Product Development and Sales Teams, it's imperative that key elements of the Kona Ride manifest in our carbon bikes. Efficiency, agility, comfort, and overall strength are all key considerations when we begin to work on the design of a carbon frame. Of course, we aim to leverage all the inherent properties of the material, but it's crucial that it still feels, rides and lasts like a Kona.
STEP 3: MATERIALS & FABRICATION
THE WEAVE: Kona Carbon Race bikes use TORAY fibers, what we have determined to be the most technologically advanced in the industry—this is the same carbon weave used throughout most Formula 1 racing cars. Our carbon weave also features NANO TECH, a process that injects carbon nano cups into the weave matrix, bringing more strength, stiffness and impact resistance to the finished product. The results are frames with industry leading weight, stiffness and durability. Our entire structure is always built with unidirectional prepreg carbon fiber underneath a frame finish that is either UD or 3K.
Kona Carbon Race frames are always built with a MONOCOQUE main triangle. While a tube-to-tube process similar to welding is cheaper to build, we choose only to use the monocoque process as it alone allows for continuous fibers where the tubes join, creating a much stronger and lighter structure.
Our production process also eliminates as much bonded-in aluminum inserts as possible. While we bond in thread inserts for durability, you won't find us taking short cuts with aluminum inserts for bottom brackets, headtubes, front derailleur mounts, or seat tubes. When we do put alloy into the frame we take very specific steps on their surface treatment and have special jigs for each step to ensure proper alignment.
Another thing you won't find inside our frames is foam. Laying up the carbon around foam mandrels is another trick that makes bikes cheaper and easier to build, but leaves the rider dragging around a bunch of heavy foam. Kona Carbon Race frames are only molded with internal air bags, which are removed after the molding process. This means our carbon frames are made from only the best ingredients: carbon fiber and epoxy.
STEP 4: TESTING
During the prototyping process, our frames are tested for weeks at a time on veritable bike torture machines that push our designs through tens of thousands of cycles. What we learn from this directly translates into making strong frames, while eliminating unnecessary material. Kona Team athletes—experts when it comes to pushing the limits of our bicycles in real world scenarios—are the next in line when it comes to testing our prototype Kona Carbon Race bikes. Even after the tests rigs and pro rider testing, our product team continues to abuse the same prototypes day-in and day-out to make sure we are building the best Kona Carbon Race frames we possibly can.
By having the headset bearing located inside the headtube (called zero stack), rather than the top and bottom, we are able to achieve a number of advantages when it comes to front-end stiffness, durability and overall riding performance. The major benefit of an internal headset 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.
For 2013, you'll find a large majority of Kona bicycles featuring zero stack and tapered headtubes. From cyclocross to cross-country, 29ers right through to longer-travel dual-suspension models, like our Entourage and Operator, a tapered headtube provides more support at the intersection of the toptube and downtube, greatly improving stability and overall performance.
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. More girth at the bottom of the headtube better distributes shock force, prolonging the bearing life of the headset itself. 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.
KONA WALKING BEAM 4-BAR LINKAGE
Since Kona first introduced the Walking Beam 4-Bar Linkage platform in 1996, we've been refining and honing the most functional, durable and performance-oriented dual-suspension platform ever invented. You'll find versions of Kona's Walking Beam 4-Bar Linkage on everything from the Hei Hei XC race bike, to our Supreme Operator, the Entourage, and on one of the best-performing, entry-level dual-suspension bikes ever made, the Tanuki.
FUNCTION AND DURABILITY: Anytime you have a pivot in anything, there is side-to-side movement, or tolerance. It's what allows the pivot to move freely. When you have pivots that are close together, the side-to-side movement in those pivots becomes amplified, what's called tolerance stacking. Kona's 4-Bar system keeps pivots as far away from each other as possible, minimizing the negative effects of tolerance stacking. Ultimately, it equates to a stiffer rear end, as well as a significant decrease in bearing and bushing wear.PURE SHOCK MOVEMENT: Another benefit of our 4-Bar system is minimized side load on the rear shock. If you have proximate pivot points and/or the shock positioned so that it is exposed to lateral forces, you have side load on the shock. Side load causes resistance, which can negatively impact suspension performance.
SHOCK LONGEVITY: With our 4-Bar system, the rear shock is protected from side-to-side forces. Side load is one of the main causes of premature seal failures. As a result, we have a very low rate of shock problems, as well as an exceptionally responsive feel to the rear suspension.
INCREDIBLE TUNE-ABILITY: By using 4-Bar, our designers are able to incorporate a huge range of suspension characteristics into our dual-suspension mountain bikes. Simply by changing the shock's positioning and configuration, we're able to make either an efficient climber or a wicked descender. For example, on our XC bikes, we can take an inherently progressive air shock and make the suspension more linear, allowing the rider to benefit from all of the bike's travel. For downhill bikes, like our Operator and Entourage, an inherently linear coil shock can be set up to be more progressive for big hits. When it comes to range of application, 4-Bar is the ultimate rear-suspension platform.
PLUSH FACTOR: With pivots, bearings and the shock itself well supported and protected from linear side load, Kona's Walking Beam 4-Bar Linkage system delivers that extraordinarily plush, smooth feel we all crave as mountain bikers. Whether it's taking the edge of a technical XC race course, the burl out of a backcountry all-day epic, or leveling out the brake bumps at your local bike park, Kona's Walking Beam 4-Bar Linkage delivers that sweet feel. Ride in, ride out.
12x142 REAR AXLES
A 12x142mm rear axle provides 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 142mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. The definition of all-mountain: DH stiffness with the speed and ease of XC.
TUBELESS COMPATIBLE RIMS
A number of 2013 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 2013, you'll find tubeless compatible rims on most of our XC race and trail bikes, as well as our carbon fiber Major Jake, Red Zone and Zone Two.
