Carbon fiber wheelsets ;are made of two components; carbon fiber and epoxy resin. When molding a carbon fiber wheel, pieces of pre-preg carbon fiber are laid into molds. Pre-preg is raw carbon fiber that is impregnated with an epoxy resin. 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 makes for a much cleaner and workable manufacturing process.

Once the pre-preg carbon is laid in the mold, it is placed in an oven where it goes through a prescribed heating cycle known as a ramp cycle. ;

Carbon Vs Aluminum Bike Frame: Pros and Cons

The frame is arguably the most important component of the bicycle. Without it, you just have a pile of parts. When it comes to choosing a frame, one of the most important considerations is the material it is made of. This guide outlines the pros and cons of carbon vs aluminum bike frames. We’ll compare the weight, durability, handling, efficiency, comfort, cost, longevity, and more to help you decide which frame material is best for your next bike. This guide covers both mountain and road bikes.

Carbon Road Frame

Carbon fiber is basically plastic that is reinforced with super-strong fibers. The material was originally developed for use in the aerospace industry where parts need to be as light and strong as possible. It offers an incredibly high strength to weight ratio. It is also extremely rigid.

Carbon fiber is made by processing a polymer into strings or filaments of carbon atoms that measure 5-10 microns in diameter. Thousands of these filaments are combined to form a tow or ribbon. Tows are bonded together with an epoxy resin. The carbon and resin material is called a composite. Composites are layered into a laminate.

This material is then shaped into bike frames using molds and heat. Manufacturers use a number of different techniques. Some frames are made by bonding together individual carbon fiber tubes with a type of glued insert. Some high-end carbon bikes use modified monocoque construction. This means that the head tube, downtube, top tube, and seat tube consist of one continuous piece.

There is a lot of variation in the way that carbon road frames
