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.

REYNOLDS 520 BUTTED CROMOLY

From one of the world’s top cromoly manufacturers, Reynolds Cycling Technology, Reynolds 520 tubes are mandrel-butted for accurate profiles and available in a wide range of shapes. Weight savings from butting provides competitively priced, light framesets that are noticeably compliant on the road or the trail, and are guaranteed to last a lifetime. The Reynolds 520 range uses the same chemistry as their 725 range but without the heat-treatment process.

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.

TUBELESS COMPATIBLE RIMS

An increasing amount of 2015 Kona models feature the benefits of tubeless compatible rims. Tubeless rims allow for tires with more puncture resistance, better tire grip on the trail, lower rolling resistance and weight savings over traditional tube + tire systems. For 2015, you’ll find tubeless compatible rims on most of our XC Race Light and Enduro bikes, as well as throughout our Cyclocross and Road platforms.

12X142 REAR AXLES

The XC/Trail/Enduro 12x142mm and the DH 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142mm/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. The take-away? 12x142 and 12x157 standards make a bike that rides better and is easier to work on.

DROPPER POST COMPATIBLE

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.

TAPERED HEADTUBE

Aside from improving the aesthetic, due to its cleaner lines and smooth transition between the fork crown and the headset cover, tapered headtubes also offer a more solid interface between forks with tapered steertubes and the bicycle frame itself, thanks to more weld contact area. More girth at the bottom of the headtube better distributes shock force, prolonging the bearing life of the headset itself, eliminates brake shudder, all while providing positive steering performance. 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.
