Kona Stuff Dirt Jump Bike Features:
Kona 7005 Aluminium
Kona 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 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.
