Product Info

The three founders of Knight Composites are bicycle industry veterans (if you follow cycling, you will immediately recognize their former employers) with decades of experience in composite frame and wheel manufacture. When they set out to create a better carbon wheel, it wasn't idle chatter - they had a very good idea of how to go about it. The end result involved both groundbreaking design and upping the expectations at the production end of the process, and fortunately for those passionate about their wheels it all came together. The Knight 27.5 Enduro Carbon Rim is a tangible result of this collaboration; a do-it-all off-road rim suitable for all types of downhill, enduro and freeride applications. 30% more compliant vertically than the major competition to readily absorb big hits, but stiffer laterally to hold firm under hard cornering, the Knight Enduro Carbon Rim is destined to shake up the singletrack near you very soon.

Product Details

Materials

EPS Molded Carbon FiberExpanded 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.
