29er

In many parts of the world, the big-wheel paradigm shift has already happened. For those where it hasn't, we aim to help usher it through. Make no mistake, the 29er revolution is upon us: great traction, incredible climbing and the ability to roll over obstacles are just a few of its attributes.

Our US-based product development team is all about the big wheel. They crush buddies on Tall Boy Tuesdays then destroy the competition on Saturdays, leaving their mark on everything from technical descents to raging singletrack. Kona has embraced 29er bike design for the last seven years with a new long-travel dual-suspension Satori, a carbon fiber King Kahuna and an aggressive all-mountain Cromoly Honzo in the lineup for 2012, and our big-wheel offerings have never been so, well, big.

kahuna

OVERVIEW

"Priest, sorcerer, magician, wizard, minister, expert in any profession." That's how the Hawaiians define "Kahuna." Our Kahuna is the same-master of all. Made of high-grade 7005 Aluminum Butted tubing, the Kahuna comes with a lifetime warranty on the frame and a blend of smooth functioning components. This fantastic 29-inch-wheel hardtail mountain bike is designed specifically for those looking to add a dash of speed to their wilderness wanderings.

TECHNOLOGY

Kona Race Light 7005 Aluminum

Kona Race Light 7005 is a lighter, more performance-oriented fabrication of our 7005 Aluminum tubing. Designed to meet Kona's discerning race specifications, Race Light 7005 uses custom butting to create thicker tubes at weld areas and at important parts of the frame, providing incredible strength and torsional integrity to the ride. We remove wall thickness in other parts of the frame set to lighten up the bike, providing the perfect balance between quickness and stiffness. The emphasis here is on performance, lightness and speed built the Kona way: a Kona Race Light 7005 bike will get you to the podium for years to come.

Sloping Toptube

Kona 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 Triangle

Short 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 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 shock 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 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.
