We control the winding angle. The CNC (computerized numerical control) machine runs an engineered layup pattern that includes a predetermined wind angle. That is to say, the angle at which the carbon filaments wrap and overwrap the turning product. The angles of winding have great importance for the final product; for example, we could create two very different products, with differing properties, by changing only the wind angle. Because a carbon bicycle fork experiences a variety of forces, we want to optimize the balance of stiffness and torsional strength, and each type of fork has a different optimal balance. Our extensive R&D gives us the key information that our engineers use to develop a particular layup.
We control the carbon fiber type. We wind each fork from constituent carbon fibers (as opposed to ‘pre-preg,’ or off the shelf, fabrics), giving us a good deal of latitude to experiment and to employ the specific amalgamation of materials that best serves a particular fork’s needs.
Wound Up controls the type of resin that impregnates the carbon filaments. Again, as with fibers, we can experiment with particular resin matrices and compounds, and optimize each for the demands that a given fork will encounter.
