Mountain Biking UK called the Process 153, “a blast to ride,” a sentiment that echoed through the mountain bike world last season. The versatility of 27.5” wheels allows for exceptional pedal efficiency and control, while 153mm of Rocker Independent Suspension and a 160mm RockShox Pike fork keep you pinned on the descents. The linkage is laterally stiff and plush thanks to oversized pivots and bearings, while the frame geometry features a low BB, a slack 66.5-degree headtube angle, 40mm stem and the shortest chainstays possible for a nimble, responsive ride. New for 2015, the seatpost is upgraded to KS Lev Integra, while the rear derailleur is upgraded to SRAM X9 Type 2.

TECHNOLOGY

ENDURO

The Process family of do-everything mountain bikes grows into new genres for 2015. Introducing two new models, including the new Process 134 SE, developed specifically for smaller and lighter riders, and the new Process 167, a long-travel 26-inch wheel model that’s sure to get the gravity fiends among us excited, the Process platform steps up as one of the most comprehensive all-mountain/enduro platforms currently on the market. Whether you’re all about the down, or love the pedal efficiency of a good climbing bike—29-inch, 27.5-inch, 26-inch wheels, big travel or short travel, there’s a Process bike for you.

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.

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.

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.

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.

ROCKER INDEPENDENT SUSPENSION

Different riders have different needs, but Trail and Enduro riders need a lot of everything—from downhill performance to efficient climbing. With Rocker Independent Suspension we found a healthy balance between the down and the up, while also designing a suspension platform that was as compact and low-slung on the frame as possible for maximum standover, stiffness and maneuverability. A consistent leverage rate curve that perfectly matches currently available air shocks creates a stable pedaling platform, while giving the rider a predictable feel throughout the travel.

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.
