Kona Walking Beam 4-Bar Linkage System

Since Kona first introduced the platform in 1996, we've been refining and honing the most functional, durable and performance-oriented dual suspension platforms ever invented. That's why you see versions of our 4-Bar linkage on everything from the Hei Hei XC Race bike to our DH Stab Supreme.

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, like in more complicated multi-pivot designs, 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, thus minimizing tolerance stacking. Ultimately, it equates a stiffer rear end, as well a significant decrease in bearing and bushing wear.

Another benefit of our 4-Bar system is minimized side load on the rear shock. If you've got close pivot points and/or the shock positioned so that it is exposed to lateral forces, you've got side load on the shock. Side load causes resistance, which negatively impacts suspension performance. Side load also causes premature seal failures.

With our 4-Bar system the rear shock is protected from side-to-side forces. As a result, we have a super low rate of shock problems, as well as a very responsive feel to the rear suspension.

Tunability: 4-Bar allows for a rainbow of different suspension characteristics, after all, this is the suspension platform used for F1 racecars. For 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 Operators, an inherently linear coil shock can be set-up to be more progressive for big hits.

Plush Factor: Void of gimmicks, with pivots, bearings and the shock itself well supported, Kona's Walking Beam 4-Bar Linkage System delivers that beautiful, super plush 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 smoothing the brake bumps at your local bike park, our 4-Bar suspension designs deliver bomber plushness, ride in, ride out.

Kona Race Light Scandium

Known to be one of the lightest and strongest alloys in the world, with superior ride characteristics, Kona Race Light Scandium is featured in many of our high-end bike models - from dual suspension mountain bikes through to some of our top ranking asphalt bikes.

Scandium is a potent grain refiner that when added to aluminum alloys, elevates the strength and durability of the material by 50%. It accomplishes this by aligning the grains of the alloy, making the metal less susceptible to failure.

Kona Race Light Scandium alloy is twice as strong as 6061 or 7005 aluminum, allowing our engineers to use much less material. Because of the material's strength, it can be butted thin enough to give the aluminum a more compliant ride similar to steel but without weight. In more specific terms, we're shaving weight from our aluminum frames by 10-to-15%, without sacrificing strength and durability.

For 2011 you'll find Kona Race Light Scandium sprinkled throughout our entire line of bikes. Most notably, our Abra Cadabra 100-160mm variable travel backcountry bike uses a Scandium frame, a testament to our commitment and faith in one of the world's most rigorous materials.

More durable than carbon

Sloping Top Tube

Kona recognized the advantages of sloping top tube frame design right from the original models we made in 1988, designed by inaugural MTB Hall of Fame legend Joe Murray. As a company, we've stayed true to this philosophy, going so far as to pioneer the design in road bikes before the benefits were understood. Today, you'll find sloping top tubes in most high-end road race bicycles. We've since stayed true to all the many positives this design brings to overall bike performance and comfort.

First, this design allows the top tube to be lower, providing more room for correct positioning and free body movement, enabling more standover clearance, which is particularly useful on dual suspension bikes that have higher bottom brackets. Riders have a more secure riding position, which is especially beneficial when riding downhill sections.

Also, the top tube is longer and more compliant. As the top and down tube become more parallel, there's less triangulation, resulting in more compliancy. So not only is the frame stronger and more responsive, but it absorbs more shock than frames with horizontal top tubes.

Compact Rear Triangle

Short chain stays and seat stays provide a perfect balance of stability and power transfer when out of the saddle and pedaling hard. Shorter seat stays also have less deflection during braking and accelerate quicker than longer stays. The shorter rear triangle also helps the bike to negotiate tight twisting sections of trail.

Hydroformed Tubing

For 2011, you'll find formed tubing on a great number of our bicycles. Hydroforming uses water specifically, but we also use Superplastic formed tubing, shaped using air, or cold formed tubing. This not only allows a tube to be tuned for compliancy on specific planes but it also improves grain alignment and increases all mechanical properties.

Hydroforming is a tube shaping technology that uses super 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.

Hydroforming proves especially advantageous at weld points where it 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 (what's sometimes called zero stack), rather than the top and bottom, we are able to achieve a wide array of advantages when it comes to front end stiffness and overall riding performance. With an internal headset, the head tube is able to take the stress directly, resulting in less play and less wear, with strong ride characteristics, and better bearing performance.

An internal headset also reduces stack height, enabling the height of the stem and bars to be more adjustable, the bike has more setup options, resulting in the best fit possible.

Tapered Head Tube

For 2011, a wide variety of Kona bicycles feature tapered head tubes, meaning the top of the head tube is 1-1/8-inches at the top, while the bottom is 1.5-inches. From our cyclocross bikes to our cross-country mountain bikes, right through to longer travel dual suspension models, like our Cadabras and CoilAirs, a tapered head tube provides more support at the intersection of the top tube and down tube.

The design also offers a more solid interface between forks with tapered steer tubes and the bicycle frame itself. More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself. The design also allows for a stronger steering position and improved balance, giving the rider more control in rough terrain.

Asymmetrical Chain Stays

When a rider puts force into the bicycles drivetrain (cranks, chain and rear cassette), not only are they propelling the bike forward, they're also putting a significant amount of torsion on the rear chain stays. 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 stay is straight, while the non-drive takes advantage of no chain rings and chain, better able to deal with the torque, effectively countering the torsional forces in the rear triangle. By putting strength where it is needed, pedaling stiffness and rider efficiency is greatly increased.

Kona Sizing and Fit

Sizing and fit have always been one of the main strengths of the Kona range, with more stock sizes available than any other bike company. With our range of bicycles expanding significantly over the last couple of years, we felt it was time to overhaul our size scale.

We started with the overwhelming request for longer top tubes on our XC mountain bikes. The average increase is ½-inch (15-20mm), which we coupled with shorter stems and slightly shorter headset stack heights. The steps between sizes were evened out to ½-inch or 1-inch increments, and there are still up to 7 sizes: from 14-inch to 22-inch on many models.

In the asphalt range, top tube lengths were marginally lengthened, with the size gaps revised to even 15 to 20mm steps. There are still up to 6 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, the overall sizing on mountain bikes and road bikes allow Kona dealers and riders to determine their fit more easily from model to model and category to category.

The net result is better fit on the entire range, with a simplified system that allows easy fine-tuning and a perfect marriage of bike and rider throughout our entire 2011 range.
