It has been designed for use with wire bead or folding tires. To achieve best possible results we have redesigned the entire rim. FIRST DELIVERY DUE MID MARCH Lightweight Standard C wheels come with all technical innovations of our current Generation III wheels. The new all-carbon spokes and the direct bonding of spokes, rim and hub is taken over from our ?Standard? and ?Obermayer? wheels. New is the rim: It has to be light and stiff like on all our wheels; additionally, the sidewall must meet extreme physical demands. Tire pressure and brake calipers both put large lateral forces on the sidewall. Add to that the heat created by braking from high velocities, and you have quite a task for the engineering department. Carbon fibers excel at withstanding longitudinal forces, and the poor heat transfer capability of carbon fiber materials let temperatures rise quickly, possibly leading to problems both at the rim and for the pad compound. We employ a special temperature resistant resin enveloping our high-tensile fibers to easily meet these demands. No rim tape is needed, further reducing overall weight.
