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.
One watt is the rate at which work is done when an object's velocity is held constant at one meter per second against a constant opposing force of one Newton. Our Kula Watt, which features our incredibly durable and lightning-fast proprietary carbon fiber frame set, takes the idea of work (you) and jumps up the speed factor (the bike). Featuring the race-bred geometry that's made the Kula famous for its agility, speed and efficiency, the Watt is the quickest bike we've ever made, all at a price that makes velocity a non-opposing force. Take that, Newton.

Kona Carbon RaceKona Carbon Race bicycle frames are built at one of the most advanced bicycle manufacturing facilities in the world: Hodaka. In addition to producing cold-forged bicycle and frame components, including wheels for Shimano and Easton, Hodaka employs an industry-leading carbon-fiber fabrication process. Combine Kona's race-proven geometries with one of the lightest, strongest and ride-savvy materials on the planet, then put them in a facility known for its innovation, leadership, and attention to detail, and you have some of the most beautifully riding bicycles around.
We will be producing a new Kona Carbon Race bicycle at Hodaka for 2012. Joining the Kula Watt, our lightning-quick 26-inch hardtail cross-country race bike, and the Major Jake, our top-of-the-line cyclocross race bike, is the King Kahuna hardtail 29er, the fastest big-wheeled mountain bike we've ever made.
- The Technology: Kona Carbon Race bicycles use Prepeg technology, a specially formulated resin matrix system reinforced with man-made fibers such as carbon, glass and aramid. When cured, the Prepegs used in Kona frames represent an incredibly solid structural material that is highly durable, temperature resistant, exceptionally stiff and lightweight. These resin formulations and fiber-impregnation technologies are designed in concert with Kona's stringent product design requirements, making our bikes the ultimate balance between stiffness, lightness and ride quality.
- Molding Process: At the bottom bracket, headtube and seat area, Kona Carbon Race frames use special internal silicon shells that increase the compression of carbon fibers layered in the mold. The method prevents the internal formation of wrinkles, another potential breaking point that, when avoided, increases the fatigue resistance of the bike and results in a lighter frame.
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.
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.
Lifetime WarrantyKona warrants to the original owner that their new Kona bicycle frame purchased from an authorized Kona dealer shall be free of defective materials or workmanship for the lifetime of ownership by the original owner. This warranty is limited to five years for carbon fiber frames and three years for electric pedal-assist frames.
During this warranty period, Kona shall repair or replace, at its sole option, the bicycle frame if Kona determines the frame is defective and subject to this limited warranty. The original owner shall pay all labor and shipping charges connected with the repair or replacement of the bicycle frame. Please see the Kona owner's manual, provided with your bicycle, for additional information.
