2012 BIKES : MTB XC RACE : HARDTAIL
MTB XC RACE
Going fast on a bike is one of the most fun things you can do on earth. Wind in the hair, dirt in the teeth, lungs full of air, pumping legs, and a body full of endorphins comprises the essence of life on two wheels. At Kona, we've been racing bikes since our inception. Twenty-three years of stage races, 24-hour hammathons, hour-long criteriums, World Cups, National Championships and backyard sufferfests. It's in our heritage and our blood. The year 2012 represents the culmination of all that we've ever learned going hard on a cross-country mountain bike.
If you've ever ridden one, you know. If you haven't, it might be time to discover the legendary race-bred Kula geometry that's taken racers to podiums from California to Chile to the Czech Republic. Known for its agility, speed, comfort, and durability, with a component grouping selected for expert racers and a frame set made with Scandium 6069 tubing, the Kula combines a lightweight ride with strength and trail sensitivity for the perfect blend of speed and fun.

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.

Sloping ToptubeKona recognized the advantages of sloping toptube frame design right from the beginning. Designed by inaugural MTB-Hall-of-Fame legend Joe Murray back in 1988, the very first Konas were some of the first mountain bikes to feature sloping toptubes (STT). As a company we've stayed true to this philosophy, going so far as to pioneer the design in road bikes long before its benefits were understood by most of the industry. Because of the many positives STT design brings to overall bike performance and comfort, you'll find it today throughout our entire line of road, commuter and mountain bikes.
Here's why: Firstly, STT design allows the toptube to be lower, providing more room for correct positioning and free body movement and enabling more standover clearance, which is particularly useful on dual-suspension bikes that have higher bottom brackets. Riders have a more secure riding position, a real benefit when riding downhill sections.
Secondly, a big benefit of STT is a longer and more compliant toptube. As the top and downtube become more parallel, there's less triangulation, resulting in more compliancy. Not only is the frame stronger and more responsive, but it absorbs more shock than frames with horizontal toptubes.
Compact Rear TriangleShort 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. The shorter rear triangle also helps the bike to negotiate tight-twisting sections of trail. Our new Entourage short-travel downhill bike is a good example of an incredibly compact rear triangle. Our goal was to create a bike that was easy to jump and trick, and could also corner aggressively. With seatstays measuring just 415mm, we've created one of the most nimble short travel DH bikes in the industry.
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.
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.
