2012 BIKES : ASPHALT : COMMUTER
It's been called a "19th-century solution to a 21st-century problem." The bicycle. When we mount one, human beings become the most efficient animals on the planet, subsequently making the bicycle the most efficient machine on the planet. The calories in one apple alone can move us miles. At Kona, we live and breathe the inherent power of our "Noblest Invention." It's an agent of change, a way to confidently move forward towards a brighter tomorrow. In essence, the bicycle represents freedom: the freedom to move, to travel, to feel good, and most importantly, while having fun along the way.
Born from our desire to make the Noblest Invention as simple and efficient as possible, the Dr. Good is all about embedding your commuter bike with great functionality and long-lasting durability. The Dr. Good features a stiff and light aluminum frame, a new Kona P2 Alloy fork with disc brake, more eyelets and increased space for easy rack and fender mounting, and a Nexus 7-speed internal drivetrain. This is a simple, straightforward workhorse. Ride superbly on a Dr. Good.

Kona 7005 AluminumKona 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 tubing on the market today. Much of our 7005 tubing is butted and/or formed, meaning the tubing'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.
Sloping ToptubeKona 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 TriangleShort 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 HeadsetBy 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.
Kona Sizing and FitSizing 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 WarrantyKona 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.
