You spend enough time on your bike. When it comes to upgrading your wheelset, there's not much point in aiming for less than the best. The Knight 27.5 Enduro / Chris King Boost Carbon Wheelset is arguably the pinnacle in freeride/enduro wheels at this point in time, and you deserve them. Knight may be a new brand on the carbon rim scene, but that's soon to change - started by three bike industry veterans with decades of carbon composite experience between them, Knight Composites' mission to "build it better than the best" has come to fruition in wheels you can ride today.
Chris King ISO Boost Hubset 28/28 Hole – Portland, OR is home to the best beer, food trucks and fixie culture in the world. And Chris King. We like all of them. Fanatical dedication to quality and that unmistakeable buzz when you're coasting . . . mmmmm.
Knight Composites 27.5" Enduro Rim – Expanded Polystyrene (EPS) molding is the standard for creating carbon frames and forks for the best race bikes in the world. Most carbon fiber rims look smooth and seamless on the outside, but what’s inside is equally as important. Making a carbon fiber rim involves compressing layers of carbon weave and epoxy resin into a mold to get the desired shape. Traditionally, inflatable bladders are used inside the rim to force the material into the mold, but because the shape of a bladder can’t be finely controlled there can sometimes be wrinkles or inconsistent thickness in the finished rim. These irregularities can lead to delamination or premature stress fractures — every fold, every wrinkle a potential point of failure. By utilizing an EPS Molding System, Knight produces internal surfaces as smooth and wrinkle-free as the exterior. This increases strength due to the uniformity of the fibers, pushing it into exactly the desired shape with consistent thickness and no wrinkles. The result is a lighter, stiffer and more consistent final product. Knight shapes the EPS forms precisely before laminating carbon fiber around them and placing the whole system in a mold. When heated, the individual beads in the EPS forms swell. Out in the open they’d reach 40 times their original size, but constrained by the mold they exert pressure on the inside of the carbon fiber, pushing it into exactly the desired shape with consistent thickness and no wrinkles. Knight is the sole rim manufacturer implementing this cutting edge technique within the manufacturing process, and combined with the use of aerospace-grade Toray® carbon fiber is producing a lighter weight, stronger, more reliable and precisely constructed rim.
