Abstract

Forming features in the surface of a bicycle component involves depositing a substance onto a substrate in a geometric pattern to form a transfer medium. Forming features may also involve positioning the transfer medium relative to an unformed bicycle component, and forming a negative of the geometric pattern in the bicycle component through the application of heat and/or pressure to the transfer medium and the unformed bicycle component. The transfer medium may be configured for use in the molding of carbon fiber reinforced plastic (“CFRP”) bicycle components and may include a substrate formed of a flexible material, and a geometric pattern formed of a hard material, the hard material different than the flexible material.

First claim

What is claimed is:

1. A transfer medium for use in molding of carbon fiber reinforced plastic (“CFRP”) bicycle components, the transfer medium comprising:
a substrate formed of a flexible material, the substrate having a first side and a second side;
a geometric pattern formed of a hard material located on the first side of the substrate, the hard material different than the flexible material; and
a release surface located on the second side of the substrate.

2. The transfer medium of claim 1 , further comprising:
the release surface formed of a release material having a low surface energy causing poor adhesion to the CFRP materials of the bicycle component.

3. The transfer medium of claim 2 , wherein the release material is different than the hard material.

4. The transfer medium of claim 2 , wherein the release material is in contact with the flexible material of the substrate and separated from the geometric pattern.

5. The transfer medium of claim 1 , wherein the geometric pattern is composed of dots or pixels.

6. The transfer medium of claim 5 , wherein the geometric pattern includes negative space.

7. The transfer medium of claim 5 , wherein the geometric pattern includes characters or numerals.

8. The transfer medium of claim 5 , wherein the geometric pattern has varying depths.

9. The transfer medium of claim 5 , wherein the geometric pattern is a raster image.

10. The transfer medium of claim 1 , wherein the geometric pattern is formed through jet deposition techniques.

11. The transfer medium of claim 1 , wherein the geometric pattern is pressed into the substrate to cause a deformation of the substrate.
