![]() You could not find a resin that produced a durable rim that also handled handled high heat. At that time, epoxy resins could only handle the high temperatures needed for brake heat if they produced a brittle part. Most of the myths mentioned in the opening of this article date back from when carbon rims were first being manufactured in the 90s and early 00s. When this happens, the carbon fiber object becomes soft and will fail.Įpoxy resin design and selection is critical for carbon fiber rims. However, all epoxy resins have what is called a “glass transition temperature” where the hardened epoxy turns from a glass back to a liquid. When the carbon fiber exits the mold, it is a hard finished part. If you were to graph the temperature over time, a ramp shape is created, hence the name ramp cycle. The oven with the mold starts off at a low temperature, ramps up to a set point temperature and then lowers to an exit temperature. Once the pre-preg carbon is laid in the mold, it is placed in an oven where it goes through a prescribed heating cycle know as a ramp cycle. Pre-preg makes for a much cleaner and workable manufacturing process. Prior to the invention of pre-preg, raw carbon fiber was laid in place and epoxy resin was applied over the carbon fiber, which was a messy and difficult process. Pre-preg is raw carbon fiber that is impregnated with an epoxy resin. When molding a carbon fiber wheel, pieces of pre-preg carbon fiber are laid into molds. How is a carbon fiber wheel made?Ĭarbon fiber rims are made of two components carbon fiber and epoxy resin. Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. Carbon fibers or carbon fibres are fibers about 5 to 10 micrometers in diameter and composed mostly of carbon atoms. It is made of loose fibers composed of carbon atoms that are then suspended in resin to create a solid material. Background & History of Carbon Wheels What is carbon fiber?Ĭarbon fiber originated in the aerospace industry. Because of this, they have a large effect on your cycling performance, safety, and comfort. They are constantly rotating and the only contact point you have with the ground when riding. Your bike’s wheels are probably the most important part of your bike. Not Recommended for Track Applications.Purchasing Carbon Wheelsets Why do bike wheels matter so much? Carbon+Forged Carbon Fiber Barrel Exceeds All Existing SAE and TUV Test Specifications.Revolutionary Proprietary Carbon Fiber Barrel.Lightweight Racing-Inspired Five V-Spoke 6061-T6 Forged Aluminum Center.If you appreciate the world’s most advanced wheel technology, want to stand apart from the crowd with unique styling & finish options, and have the means to afford the very finest, then our made-to-order Carbon+Forged CF201 wheel is quite literally created just for you. ![]() ![]() ![]() (Note: The Carbon+Forged carbon fiber barrel preserves the standard high-gloss natural carbon weave finish.) And like any Forgeline wheel, the CF201’s forged aluminum center is available in the full array of customizable finish options. The CF201 is available in 18, 19, 20, 21, 22, and 23-inch fitments, each uniquely engineered for modern exotic sport and luxury vehicle applications. Tested by an independent automotive industry laboratory, they have proven to be incredibly strong and robust, exceeding all existing SAE and TUV test specifications. The CF201’s super-lightweight carbon fiber barrel creates an attractive and visually distinctive rim that is 40% lighter than its aluminum equivalent, delivering a significant weight reduction to the wheel’s outer perimeter, where it has the greatest reduction in unwanted inertia and yields real-world improvements to acceleration, braking, cornering traction, ride quality, NVH (noise, vibration, & harshness), driver/passenger comfort, and fuel economy.įorgeline Carbon+Forged carbon fiber barrels are also engineered and tested to deliver industry-leading levels of fatigue strength, impact/damage resistance, and deflection stiffness. The CF201 takes advantage of it’s carbon fiber barrel with a lightweight racing-inspired five V-spoke forged aluminum center design and aggressive I-beam machining details to yield a wheel with absolutely impressive performance metrics: very low static mass, very low rotational inertia, minimal deflection, and excellent fatigue strength! The lightweight Carbon+Forged CF201 wheel combines a weight-optimized CNC-machined forged aluminum center with a revolutionary proprietary carbon fiber barrel to deliver the ultimate in technological advancement, exclusive styling, and unparalleled performance. ![]()
