TECHNOLOGY

TRAIL 27.5" HT

Last year we introduced a number of 27.5-inch-wheel MTB XC Trail bikes, including the Explosif, Cinder Cone and Blast. With its great rollability, smart handling and increased traction, for 2015 we couldn’t help but grow the platform by leaps and bounds. While the wheel size works well in applications like Enduro and all-mountain, it also happens to fit beautifully on more recreational models. This year you’ll find the Tika, Fire Mountain and Lanai jump into the modern age, creating a diverse, fun grouping of bikes from expert straight through to entry-level.

KONA 6061 ALUMINUM BUTTED

Kona 7005 and 6061 Aluminum alloys are used extensively throughout our fleet of mountain and asphalt bicycles. A tough, durable, affordable, light alloy, both Kona 7005 and 6061 deliver fantastic, reliable performance that lasts for thousands of rides. Much of our 7005/6061 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 strength and ride characteristics depending on its intended application.

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. A more compact rear triangle also helps the bike to negotiate tight-twisting sections of trail. The Honzo, Operator and Process 111 are good examples of 2015 bikes with incredibly compact rear triangles: quick, aggressive in corners, easy to maneuver and laterally stiff.

INTERNAL HEADSET

The major benefit of an internal headset, whereby the bearing cups are actually pressed into the frame and are easily removable, 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.

DROPPER POSTS

Dropper posts are a key element in riding technical singletrack. No surprise then, for 2015 we’ve spec’d dropper posts on numerous models throughout our Enduro and MTB Trail platforms, featuring the lightweight and proven seat posts from Kind Shock. New for 2015, you’ll find internal and external routing for dropper posts throughout our Race Light XC mountain bikes.

27.5" WHEELS

The benefits of the 27.5-inch wheel are simple: they roll over obstacles and track better than 26-inch wheels, but are more maneuverable and nimble than 29-inch ones. They are, quite literally, the best of both worlds, effectively increasing overall performance and rider confidence. No surprise then, that 27.5-inch wheels have found their way throughout our Mountain Bike range. You’ll find the wheel size throughout our Enduro platform and now throughout many of our traditional mountain bikes, like the Cinder Cone, Blast and Lana’i.
