2012 BIKES : MTB TRAIL/ALL MOUNTAIN : DUAL SUSPENSION
MTB TRAIL/ALL MOUNTAIN
No matter the complexity that tries to invade your day-to-day, there's a place where the rules are always the same. It's a place where effort is graced with reward, where the moment reigns supreme, and all the worry and want of the modern world is washed away in a tide of brown and green. It's called "trail," and we build some of the world's most incredible vessels for riding them. Ah, yes, the ways of the world are quite simple, especially when you're on board an expertly crafted mountain bike.
In case you didn't already know, the Tanuki has eight special traits: a hat to protect against bad weather; big eyes to make good decisions; a sake bottle to represent virtue; a big tail for steadiness and strength; gargantuan testicles for obvious reasons; cash for confidence; a big belly to symbolize decisiveness; and a friendly smile. The Tanuki Supreme puts these traits on a bike that can do it all, from XC racing to light-duty all-mountain, from backcountry epics to backyard loops. You go mystical Japanese raccoon dog. You go.

Kona Scandium 6069Known to be one of the lightest and strongest alloys in the world, and originally developed by the aerospace industry, new Kona Scandium 6069 is featured in many of our high-end bike models, from dual-suspension mountain bikes through to some of our top-ranking asphalt rides.
Scandium is a rare earth metal and potent grain refiner that, when added to aluminum alloy, elevates the strength and durability of the material by 50 per cent. Scandium aligns the grains of the alloy, making the metal less susceptible to failure. Scandium alloys are twice as strong as 6061 or 7005 aluminum, which means our Product Team uses much less material. Because of a Scandium alloy's strength, it can be butted thinly enough so the aluminum gives a more compliant feel that's similar to steel but without weight. In more specific terms, we're shaving weight off our aluminum frames by 10 to 15 per cent, without sacrificing strength and durability.
New Kona Scandium 6069, recently made available for 2012, comes with yield strengths that are about 40 per cent higher than previous scandium alloys. The result is the strongest per-weight aluminum alloy ever made. Because of its fibrous or fine-grained structure, Scandium 6069 alloy reveals a unique combination of high strength, high toughness, good corrosion resistance and excellent fatigue strength.
For 2012, you'll find Kona Scandium 6069 sprinkled throughout our bike platforms, most notably in the Abra Cadabra 100-160mm variable travel backcountry bike and the Big Kahuna 29er hardtail.

Hydroformed TubingHydroforming is a tube-shaping technology that uses high-pressure liquid to form the shape of a tube and align its grain structure. Quite simply, the technology delivers a 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.
Hydroformed tubing is especially advantageous at weld points where tubes can be flared to increase weld areas, adding strength without adding weight in the form of extra gussets. The result is a strong, flawless frame with great lateral stability, durability and responsiveness. Not to mention, it looks real sharp too.
Internal HeadsetBy 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.
Tapered HeadtubeFor 2012, you'll find a large majority of Kona bicycles featuring zero stack, 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.
The design also offers 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.
Asymmetrical ChainstaysWhen a rider puts force into a bicycle's drivetrain (cranks, chain and rear cassette), they are propelling the bike forward and also putting a significant amount of torsion on the rear chainstays. Because the drivetrain is on one side of the bicycle, the frame wants to flex laterally. It is the one element of bike design that's not in perfect balance.
Used primarily on our dual-suspension mountain bikes, asymmetrical stays help to stiffen the rear end by compensating for the offset forces of this imbalance. The drive side chainstay is straight, while the non-drive side chainstay takes advantage of no chain rings and chain, incorporating an asymmetrical stay that's better able to counter the torsional forces in the rear triangle. By putting strength where it is needed, pedaling stiffness and rider efficiency is greatly increased.
Asymmetrical stays also allow us to use a shorter and lighter non-drive side chainstay. The weight saved can be added to the drive side chainstay so that it can take heavy rotating loads generated from powerful multi-piston hydraulic brakes and large rotors.
Kona Walking Beam 4-Bar LinkageSince 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. Not only is it the preferred suspension system for F1 race cars, you'll also find versions of Kona's Walking Beam 4-Bar Linkage on everything from the Hei Hei XC race bike, to our Supreme Operator DH race bike, 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 close 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.
Kona Sizing and FitSizing and fit have always been one of the main strengths of the Kona Ride. With more stock sizes available than any other bike company, our size scale is designed to be continuous from platform to platform and is easy to understand from the perspective of the consumer because our simplified system allows easy fine-tuning that creates a perfect marriage of bike and rider.
On our Trail/All-Mountain and XC Race bikes, we feature longer toptubes coupled with shorter stems and slightly shorter headset stack heights. The steps between sizes are at half-inch to one-inch increments, with up to seven sizes that can range from 14 to 22 inches on many models. In the asphalt range, size gaps are at even 15 to 20mm steps. There are still up to six sizes, from 46cm to 61cm on most models.
When it's called for, seat posts are either offset or straight to maximize the reach and power output of the rider. More importantly, our comprehensive bike sizing allows Kona dealers and riders to determine their fit more easily from model to model and category to category.
