OVERVIEW DETAILED SPECS TECHNOLOGY REVIEWS GLOSSARY

We continue to make refinements to our cromoly steel dirt jump/street bike. A new head tube, smoother lines with curves instead of tack welded hard lines, and a press fit Spanish bottom bracket with a bigger bearing that's better for BMX cranks. Basically, no fooling around. The bike comes with a 20mm fork axle, half link chain, integrated seat clamp so the top tube is lower, Pivotal saddle and seat post that's lighter and strong. Toss on hydraulic disc brakes and a super sexy clearcoated raw steel finish.

Steel is Real

We've never given up on the original mountain bike material. You'll find the simplicity, strength, comfort, resilience, and playfulness of steel sprinkled throughout our line of road, asphalt and mountain bikes.

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.
