Kona 7005 Aluminum

Kona 7005 Aluminum is used extensively throughout our fleet of mountain, asphalt and road bicycles. A tough, durable, affordable, light alloy, Kona 7005 delivers fantastic, reliable performance that lasts for thousands of rides. It is, by far, the ultimate aluminum rám on the market today. Much of our 7005 rám is butted and/or formed, meaning the frame's wall thickness can be increased or decreased, as well as shaped, allowing us to fine-tune a particular frame's ride characteristics depending on its intended application.

Hydroformed frame

Hydroforming 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 rám in the world. The process results in a seamless, continuous, aligned piece of metal-right down to the fiber structure itself.

Hydroformed frame 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 Headset

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.

Tapered Headtube

For 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 tlumič 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. 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 zadní tlumič. If you have close pivot points and/or the tlumič positioned so that it is exposed to lateral forces, you have side load on the tlumič. Side load causes resistance, which can negatively impact suspension performance.
• tlumič Longevity: With our 4-Bar system the zadní tlumič 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 tlumič 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 tlumič'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 tlumič 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 tlumič 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 tlumič 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 Fit

Sizing 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 Warranty

Kona 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.
