Abstract

A bicycle component comprises a first structural member made of a conducting material, an electrical insulation layer provided to the first structural member, and a second structural member configured to be attached to the electrical insulation layer by adhesive.

First claim

What is claimed is:

1. A bicycle component comprising:
a first structural member made of a conducting material;
an electrical insulation layer provided to the first structural member; and
a second structural member is attached to the electrical insulation layer by adhesive, wherein
the electrical insulation layer is provided between the first structural member and the second structural member.

2. The bicycle component according to claim 1 , wherein
the electrical insulation layer includes synthetic resin.

3. The bicycle component according to claim 1 , wherein
the electrical insulation layer includes an electrodeposition coating layer.

4. The bicycle component according to claim 1 , wherein
the first structural member includes a metallic material.

5. The bicycle component according to claim 4 , wherein
the metallic material includes aluminum.

6. The bicycle component according to claim 5 , wherein
the first structural member includes an anodized oxide layer.

7. The bicycle component according to claim 1 , wherein
the second structural member includes a non-metallic material.

8. The bicycle component according to claim 7 , wherein
the non-metallic material includes carbon fiber reinforced plastic.

9. The bicycle component according to claim 1 , further comprising
an additional electrical insulation layer provided to the second structural member, wherein
the electrical insulation layer of the first structural member is attached to the additional electrical insulation layer of the second structural member by the adhesive.

10. The bicycle component according to claim 9 , wherein
the second structural member is made of a conducting material.

11. The bicycle component according to claim 1 , wherein
the bicycle component includes a bicycle rim.

12. A bicycle rim comprising:
a cover member made of a conducting material;
an electrical insulation layer provided to the cover member; and
a base member is attached to the electrical insulation layer by adhesive, wherein
the electrical insulation layer is provided between the cover member and the base member.

13. The bicycle rim according to claim 12 , wherein
the electrical insulation layer includes synthetic resin.

14. The bicycle rim according to claim 12 , wherein
the electrical insulation layer includes an electrodeposition coating layer.

15. The bicycle rim according to claim 12 , further comprising
a spoke attachment member that is a separate member from the base member and the cover member.

16. The bicycle rim according to claim 12 , wherein
the cover member includes a metallic material.

17. The bicycle rim according to claim 16 , wherein
the metallic material includes aluminum.

18. The bicycle rim according to claim 17 , wherein
the cover member includes an anodized oxide layer.

19. The bicycle rim according to claim 12 , wherein
the base member includes a non-metallic material.

20. The bicycle rim according to claim 19 , wherein
the non-metallic material includes carbon fiber reinforced plastic.

21. The bicycle rim according to claim 12 , wherein
the base member includes a truss structure defining at least one opening, and
the cover member at least partly covers the at least one opening of the base member.

22. The bicycle rim according to claim 21 , wherein
the truss structure includes at least one slanting member extending to intersect with a radial direction with respect to a rotational center axis of the bicycle rim.

23. The bicycle rim according to claim 21 , wherein
the truss structure includes at least one radially extending member radially extending along a radial direction with respect to a rotational center axis of the bicycle rim.

24. The bicycle rim according to claim 21 , wherein
the truss structure includes a plurality of slanting members extending to intersect with a radial direction with respect to a rotational center axis of the bicycle rim.

25. The bicycle rim according to claim 21 , wherein
the truss structure includes a plurality of radially extending members radially extending along a radial direction with respect to a rotational center axis of the bicycle rim.

26. The bicycle rim according to claim 21 , wherein
the truss structure defines a plurality of openings, and
the cover member at least partly covers the plurality of opening of the base member.

27. The bicycle rim according to claim 21 , wherein
the cover member entirely covers the at least one opening of the base member.

28. The bicycle rim according to claim 26 , wherein
the cover member entirely covers the plurality of openings of the base member.
