OVERVIEW DETAILED SPECS TECHNOLOGY REVIEWS GLOSSARY

Custom designed for the sensei of slopestyle, Paul Basagoitia, the Bass returns as the most dominant slopestyle bike of all time. New for 2011, we've incorporated shorter chainstays for increased trick-ability, a modified seat tube, and a zero stack tapered head tube-nose case jumps as much as you dare, the Bass can take it. The bike is more affordable for 2011, with micro drive chromed BMX inspired cranks, smaller drive train (28t x 14t), and Marzocchi DJ2 with 20mm axle. More core. More Bass.

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.

7005 Aluminum

Aluminum is currently the most widely used tubing material in the bicycle industry. Aluminum is often mixed with a number of other elements to create aluminum alloys featuring a host of different ride characteristics, while increasing mechanical properties. Much of our tubing is butted and/or formed, meaning that the wall thickness of the tubing can be increased or decreased, as well as shaped, allowing us to fine tune a particular frame's ride characteristics depending on the application. Kona uses butted 7005 aluminum extensively throughout our entire range of mountain, asphalt and road bicycles. A tough, durable, affordable, light, and dependable alloy, 7005 delivers great performance that lasts for thousands of rides. It is, by far and away, the ultimate aluminum tubing on the market today.

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.

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.

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.
